More than half of these are now children and teenagers. By 2030, tobacco is expected to be the single biggest cause of death worldwide, accounting for about 10 million deaths per year. Increased activity to reduce this burden is a priority for both the World Health Organization (WHO) and the World Bank as part of their missions to improve health and reduce poverty. By enabling efforts to identify and implement ef- fective tobacco control policies, particularly in children, both organizations would be fulfilling their missions and helping to reduce the suffering and costs of the smoking epidemic. Tobacco is different from many other health challenges. Cigarettes are demanded by consumers and form part of the social custom of many societies. Cigarettes are extensively traded and profitable commodities, whose produc- tion and consumption have an impact on the social and economic resources of developed and developing countries alike. The economic aspects of tobacco use are therefore critical to the debate on its control. However, until recently these aspects have received little global attention. This report aims to help fill that gap. It covers key issues that most societ- ies and policymakers face when they think about tobacco or its control. The report is an important part of the partnership between the WHO and the World Bank. The WHO, the principal international agency on health issues, has taken the lead in responding to the epidemic with its Tobacco Free Initiative. The World Bank aims to work in partnership with the lead agency, offering its particular analytic resources in economics. Since 1991, the World Bank has had a formal policy on tobacco, in recognition of the harm that it does to health. The policy prohibits the Bank from lending on tobacco and encourages control efforts. Ix X CURBING THE EPIDEMIC The report is also timely. In light of the rising death toll from tobacco, many governments, nongovernmental organizations, and agencies within the United Nations (UN) system, such as UNICEF and the Food and Agricultural Organization, and the International Monetary Fund are examining their own policies on tobacco control. This report draws on many productive collabora- tions that have arisen from such reviews at national and international levels. This report is intended mainly to address the concerns raised by policymakers about the impact of tobacco control policies on economies. The benefits of tobacco control for health, especially for the world's children, are clear. There are, however, costs to tobacco control, and policymakers need to weigh these carefully. In cases where tobacco control policies impose costs on the poorest in society, governments clearly have a responsibility to help reduce these costs through, for example, transition schemes for poor tobacco farmers. Tobacco is among the greatest causes of preventable and premature deaths in human history. Yet comparatively simple and cost-effective policies that can reduce its devastating impact are already available. For governments intent on improving health within the framework of sound economic policies, action to control tobacco represents an unusually attractive choice.

Preface THIS report has its origins in the converging efforts of several part- ners to address a shared problem: the relative neglect of economic contribu- tions to the debate on tobacco control. In 1997, at the 10th World Conference on Tobacco in Beijing, China, the World Bank organized a consultation ses- sion on the economics of tobacco control. The meeting was part of an ongoing review of the Bank's own policies. There was clear recognition at this meeting that insufficient global attention was being paid to the economics of the smok- ing epidemic. The meeting's participants also agreed that the discipline of eco- nomics was not being applied to tobacco control in many countries, and that even where economic approaches were being used, their methodology was of variable quality. At the same time that the World Bank began reviewing its policies, econo- mists at the University of Cape Town, South Africa, had begun a project on the economics of tobacco control for Southern Africa. These initiatives were brought together, in partnership with economists at the University of Lausanne, Switzerland, and others, to form a wider review. The work culminated in a conference in Cape Town in February 1998. The proceedings of that confer- ence are published separately.' The collaboration led to a broader analysis of the economics of tobacco control, involving economists and others from a wide range of countries and institutions. Some of the studies resulting from this analysis will be published shortly.2 This report summarizes the findings of those studies that are relevant to policymakers. xi XII CURBING THE EPIDEMIC Notes 1.

By 2030, per- haps a little sooner, the proportion will be one in six, or 10 million deaths per year-more than any other single cause. Whereas until recently this epidemic of chronic disease and premature death mainly affected the rich countries, it is now rapidly shifting to the developing world. By 2020, seven of every 10 people killed by smoking will be in low- and middle-income nations. Why this report? Few people now dispute that smoking is damaging human health on a global scale. However, many governments have avoided taking action to control smok- ing-such as higher taxes, comprehensive bans on advertising and promotion, or restrictions on smoking in public places-because of concerns that their interventions might have harmful economic consequences. For example, some policymakers fear that reduced sales of cigarettes would mean the permanent loss of thousands of jobs; that higher tobacco taxes would result in lower gov- ernment revenues; and that higher prices would encourage massive levels of cigarette smuggling. This report examines the economic questions that policymakers must ad- dress when contemplating tobacco control. It asks whether smokers know the risks and bear the costs of their consumption choices, and explores the options for governments if they decide that intervention is justified. The report as- sesses the expected consequences of tobacco control for health, for econo- 1 2 CURBING THE EPIDEMIC mies. and for individuals. It demonstrates that the economic fears that have deterred policymakers from taking action are largely unfounded. Policies that reduce the demand for tobacco, such as a decision to increase tobacco taxes, would not cause long-term job losses in the vast majority of countries. Nor would higher tobacco taxes reduce tax revenues; rather, revenues would climb in the medium term. Such policies could, in sum, bring unprecedented health benefits without harming economies. Current trends About 1.1 billion people smoke worldwide. By 2025, the number is expected to rise to more than 1.6 billion. In the high-income countries, smoking has been in overall decline for decades, although it continues to rise in some groups. In low- and middle-income countries, by contrast, cigarette consumption has been increasing. Freer trade in cigarettes has contributed to rising consump- tion in these countries in recent years. Most smokers start young. In the high-income countries, about eight out of 10 begin in their teens. While most smokers in low- and middle-income countries start in the early twenties, the peak age of uptake in these countries is fallirg. In most countries today, the poor are more likely to smoke than the rich. The health consequences The health consequences of smoking are twofold. First, the smoker rapidly becomes addicted to nicotine. The addictive properties of nicotine are well documented but are often underestimated by the consumer. In the United States, studies among final-year high school students suggest that fewer than two out of five smokers who believe that they will quit within five years actually do quit. About seven out of 10 adult smokers in high-income countries say they regret starting, and would like to stop. Over decades and as knowledge has increased, the high-income countries have accumulated a substantial number of former smokers who have successfully quit. However, individual attempts to quit have low success rates: of those who try without the assistance of ces- sation programs, about 98 percent will have started again within a year. In low- and middle-income countries, quitting is rare. Smoking causes fatal and disabling disease, and, compared with other risky behaviors, the risk of premature death is extremely high. Half of all long-term smokers will eventually be killed by tobacco, and of these, half will die during productive middle age, losing 20 to 25 years of life. The diseases associated with smoking are well documented and include cancers of the lung and other organs, ischemic heart disease and other circulatory diseases, and respiratory SUMMARY 3 diseases such as emphysema. In regions where tuberculosis is prevalent, smok- ers also face a greater risk than nonsmokers of dying from this disease. Since the poor are more likely to smoke than the rich, their risk of smok- ing-related and premature death is also greater. In high- and middle-income countries, men in the lowest socioeconomic groups are up to twice as likely to die in middle age as men in the highest socioeconomic groups, and smoking accounts for at least half their excess risk. Smoking also affects the health of nonsmokers. Babies born to smoking mothers have lower birth weights, face greater risks of respiratory disease, and are more likely to die of sudden infant death syndrome than babies born to nonsmokers. Adult nonsmokers face small but increased risks of fatal and dis- abling disease from exposure to others' smoke. Do smokers know their risks and bear their costs? Modem economic theory holds that consumers are usually the best judges of how to spend their money on goods and services. This principle of consumer sovereignty is based on certain assumptions: first, that the consumer makes rational and informed choices after weighing the costs and benefits of pur- chases, and, second, that the consumer incurs all costs of the choice. When all consumers exercise their sovereignty in this way-knowing their risks and bearing their costs-then society's resources are, in theory, allocated as effi- ciently as possible. This report examines consumers' incentives to smoke, asks whether their choice to do so is like other consumption choices, and whether it results in an efficient allocation of society's resources, before discussing the implications for governments. Smokers clearly perceive benefits from smoking, such as pleasure and the avoidance of withdrawal, and weigh these against the private costs of their choice. Defined this way, the perceived benefits outweigh the perceived costs, otherwise smokers would not pay to smoke. However, it appears that the choice to smoke may differ from the choice to buy other consumer goods in three specific ways. First, there is evidence that many smokers are not fully aware of the high risks of disease and premature death that their choice entails. In low- and middle- income countries, many smokers may simply not know about these risks. In China in 1996, for example, 61 percent of smokers questioned thought that tobacco did them "little or no harm." In high-income countries, smokers know they face increased risks, but they judge the size of these risks to be lower and less well established than do nonsmokers, and they also minimize the personal relevance of these risks. Second, smoking is usually started in adolescence or early adulthood. Even when they have been given information, young people do not always have the 4 CURBING THE EPIDEMIC capacity to use it to make sound decisions. Young people may be less aware than adults of the risk to their health that smoking poses. Most new recruits and would-be smokers also underestimate the risk of becoming addicted to nicotine. As a result, they seriously underestimate the future costs of smok- ing-that is, the costs of being unable in later life to reverse a youthful deci- sion to smoke. Societies generally recognize that adolescent decision-making capacity is limited, and restrict young people's freedom to make certain choices, for example, by denying them the right to vote or to marry until a certain age. Likewise, societies may consider it valid to restrict young people's freedom to choose to become addicted to smoking, a behavior that carries a much greater risk of eventual death than most other risky activities in which young people engage. Third, smoking imposes costs on nonsmokers. With some of their costs bome by others, smokers may have an incentive to smoke more than they would if they were bearing all the costs themselves. The costs to nonsmokers clearly include health damage as well as nuisance and irritation from exposure to environmental tobacco smoke. In addition, smokers may impose financial costs on others. Such costs are more difficult to identify and quantify, and are variable in place and time, so it is not yet possible to determine how they might affect individuals' incentives to smoke more or less. However, we briefly dis- cuss two such costs, healthcare and pensions. In high-income countries, smoking-related healthcare accounts for be- tween 6 and 15 percent of all annual healthcare costs. These figures will not necessarily apply to low- and middle-income countries, whose epidemics of smoking-related diseases are at earlier stages and may have other qualitative differences. Annual costs are of great importance to governments but, for indi- vidual consumers, the key question is the extent to which the costs will be borne by themselves or by others. In any given year, smokers' healthcare costs will on average exceed non- smokers'. If healthcare is paid for to some extent by general public taxation, nonsmokers will thus bear a part of the smoking population's costs. However, some analysts have argued that, because smokers tend to die earlier than non- smokers, their lifetime healthcare costs may be no greater, and possibly even smaller, than nonsmokers'. This issue is controversial, but recent reviews in high-income countries suggest that smokers' lifetime costs are, after all, some- what higher than nonsmokers', despite their shorter lives. However, whether higher or lower, the extent to which smokers impose their costs on others will depend on many factors, such as the existing level of cigarette taxes, and how much healthcare is provided by the public sector. In low- and middle-income countries, meanwhile, there have been no reliable studies of these issues. The question of pensions is equally complex. Some analysts in high-in- come countries have argued that smokers "pay their way" by contributing to SUMMARY 5 public pension schemes and then dying earlier, on average, than nonsmokers. However, this question is irrelevant to the low- and middle-income countries where most smokers live, because public pension coverage in these countries is low. In sum, smokers certainly impose some physical costs, including health damage, nuisance, and irritation, on nonsmokers. They may also impose fi- nancial costs, but the scope of these is still unclear. Appropriate responses It appears unlikely, then, that most smokers either know their full risks or bear the full costs of their choice. Governments may consider that intervention is therefore justified, primarily to deter children and adolescents from smoking and to protect nonsmokers, but also to give adults all the information they need to make an informed choice. Governments' interventions should ideally remedy each identified prob- lem specifically. Thus, for example, children's imperfect judgments about the health effects of smoking would most specifically be addressed by improving their education and that of their parents, or by restricting their access to ciga- rettes. But adolescents respond poorly to health education, perfect parents are rare, and existing forms of restriction on cigarette sales to the young do not work, even in the high-income countries. In reality, the most effective way to deter children from taking up smoking is to increase taxes on tobacco. High prices prevent some children and adolescents from starting and encourage those who already smoke to reduce their consumption. Taxation is a blunt instrument, however, and if taxes on cigarettes are raised, adult smokers will tend to smoke less and pay more for the cigarettes that they do purchase. In fulfilling the goal of protecting children and adoles- cents, taxation would thus also be imposing costs on adult smokers. These costs might, however, be considered acceptable, depending upon how much societies value curbing consumption in children. In any case, one long-term effect of reducing adult consumption may be to further discourage children and adolescents from smoking. The problem of nicotine addiction would also need to be addressed. For established smokers who want to quit, the cost of withdrawal from nicotine is considerable. Governments might consider interventions to help reduce those costs as part of the overall tobacco control package. Measures to reduce the demand for tobacco We turn now to a discussion of measures for tobacco control, evaluating each in turn. 6 CURBING THE EPIDEMIC Raising taxes Evidence from countries of all income levels shows that price increases on cigarettes are highly effective in reducing demand. Higher taxes induce some smokers to quit and prevent other individuals from starting. They also reduce the number of ex-smokers who return to cigarettes and reduce consumption among continuing smokers. On average, a price rise of 10 percent on a pack of cigarettes would be expected to reduce demand for cigarettes by about 4 percent in high-income countries and by about 8 percent in low- and middle- income countries, where lower incomes tend to make people more responsive to price changes. Children and adolescents are more responsive to price rises than older adults, so this intervention would have a significant impact on them. Models for this report show that tax increases that would raise the real price of cigarettes by 10 percent worldwide would cause 40 million smokers alive in 1995 to quit, and prevent a minimum of 10 million tobacco-related deaths. The price rise would also deter others from taking up smoking in the first place. The assumptions on which the model is based are deliberately con- servative, and these figures should therefore be regarded as minimum esti- mates. As many policymakers are aware, the question of what the right level of tax should be is a complex one. The size of the tax depends in subtle ways on empirical facts that may not yet be available, such as the scale of the costs to nonsmokers and income levels. It also depends on varying societal values, such as the extent to which children should be protected, and on what a society hopes to achieve through the tax, such as a specific gain in revenue or a spe- cific reduction in disease burden. The report concludes that, for the time be- ing, policymakers who seek to reduce smoking should use as a yardstick the tax levels adopted as part of the comprehensive tobacco control policies of countries where cigarette consumption has fallen. In such countries, the tax component of the price of a pack of cigarettes is between two-thirds and four- fifths of the retail cost. Currently, in the high-income countries, taxes average about two-thirds or more of the retail price of a pack of cigarettes. In lower- income countries taxes amount to not more than half the retail price of a pack of cigarettes. Nonprice measures to reduce demand Beyond raising the price, governments have also employed a range of other effective measures. These include comprehensive bans on advertising and pro- motion of tobacco; information measures such as mass media counter-adver- tising, prominent-health waming labels, the publication and dissemination of SUMMARY 7 research findings on the health consequences of smoking as well as restric- tions on smoking in work and public places. This report provides evidence that each of these measures can reduce the demand for cigarettes. For example, "information shocks," such as the publi- cation of research studies with significant new information on the health ef- fects of smoking, reduce demand. Their effect appears to be greatest when a population has relatively little general awareness of the health risks. Compre- hensive bans on advertising and promotion can reduce demand by around 7 percent, according to econometric studies in high-income countries. Smoking restrictions clearly benefit nonsmokers, and there is also some evidence that restrictions can reduce the prevalence of smoking. Models developed for this report suggest that, employed as a package, such nonprice measures used globally could persuade some 23 million smok- ers alive in 1995 to quit and avert the tobacco-attributable deaths of 5 million of them. As with the estimates for tax increases, these are conservative esti- mates. Nicotine replacement and other cessation therapies A third intervention would be to help those who wish to quit by making it easier for them to obtain nicotine replacement therapy (NRT) and other cessa- tion interventions. NRT markedly increases the effectiveness of cessation ef- forts and also reduces individuals' withdrawal costs. Yet in many countries, NRT is difficult to obtain. Models for this study suggest that if NRT were made more widely available, it could help to reduce demand substantially. The combined effect of all these demand-reducing measures is not known, since smokers in most countries with tobacco control policies are exposed to a mixture of them and none can be studied strictly in isolation. However, there is evidence that the implementation of one intervention supports the success of others, underscoring the importance of implementing tobacco controls as a package. Together, in sum, these measures could avert many millions of deaths. Measures to reduce the supply of tobacco While interventions to reduce demand for tobacco are likely to succeed, mea- sures to reduce its supply are less promising. This is because, if one supplier is shut down, an alternative supplier gains an incentive to enter the market. The extreme measure of prohibiting tobacco is unwarranted on economic grounds as well as unrealistic and likely to fail. Crop substitution is often pro- posed as a means to reduce the tobacco supply, but there is scarcely any evi- dence that it reduces consumption, since the incentives to farmers to grow tobacco are currently much greater than for most other crops. While crop sub- 8 CURBING THE EPIDEMIC stitution is not an effective way to reduce consumption, it may be a useful strategy where needed to aid the poorest tobacco farmers in transition to other livelihoods, as part of a broader diversification program. Similarly, the evidence so far suggests that trade restrictions, such as im- port bans, will have little impact on cigarette consumption worldwide. In- stead, countries are more likely to succeed in curbing tobacco consumption by adopting measures that effectively reduce demand and applying those measures symmetrically to imported and domestically produced cigarettes. Likewise, in a framework of sound trade and agriculture policies, the subsi- dies on tobacco production that are found mainly in high-income countries make little sense. In any case, their removal would have little impact on total retail price. However, one supply-side measure is key to an effective strategy for to- bacco control: action against smuggling. Effective measures include promi- nent tax stamps and local-language warnings on cigarette packs, as well as the aggressive enforcement and consistent application of tough penalties to deter smugglers. Tight controls on smuggling improve governments' revenue yields from tobacco tax increases. The costs and consequences of tobacco control Policymakers traditionally raise several concerns about acting to control to- bacco. The first of these concerns is that tobacco controls will cause perma- nent job losses in an economy. However, falling demand for tobacco does not mean a fall in a country's total employment level. Money that smokers once spent on cigarettes would instead be spent on other goods and services, gener- ating other jobs to replace any lost from the tobacco industry. Studies for this report show that most countries would see no net job losses, and that a few would see net gains, if tobacco consumption fell. There are however a very small number of countries, mostly in Sub-Sa- haran Africa, whose economies are heavily dependent on tobacco farming. For these countries, while reductions in domestic demand would have little impact, a global fall in demand would result in job losses. Policies to aid ad- justment in such circumstances would be essential. However, it should be stressed that, even if demand were to fall significantly, it would occur slowly, over a generation or more. A second concern is that higher tax rates will reduce government rev- enues. In fact, the empirical evidence shows that raised tobacco taxes bring greater tobacco tax revenues. This is in part because the proportionate reduc- tion in demand does not match the proportionate size of the tax increase, since addicted consumers respond relatively slowly to price rises. A model devel- oped for this study concludes that modest increases in cigarette excise taxes of SUMMARY 9 10 percent worldwide would increase tobacco tax revenues by about 7 percent overall, with the effects varying by country. A third concern is that higher taxes will lead to massive increases in smug- gling, thereby keeping cigarette consumption high but reducing government revenues. Smuggling is a serious problem, but the report concludes that, even where it occurs at high rates, tax increases bring greater revenues and reduce consumption. Therefore, rather than foregoing tax increases, the appropriate response to smuggling is to crack down on criminal activity. A fourth concern is that increases in cigarette taxes will have a dispropor- tionate impact on poor consumers. Existing tobacco taxes do consume a higher share of the income of poor consumers than of rich consumers. However, policymakers' main concem should be over the distributional impact of the entire tax and expenditure system, and less on particular taxes in isolation. It is important to note that poor consumers are usually more responsive to price increases than rich consumers, so their consumption of cigarettes will fall more sharply following a tax increase, and their relative financial burden may be correspondingly reduced. Nonetheless, their loss of perceived benefits of smok- ing may be comparatively greater. Is tobacco control worth paying for? For govemments considering intervention, an important further consideration is the cost-effectiveness of tobacco control measures relative to other health interventions. Preliminary estimates were performed for this report in which the public costs of implementing tobacco control programs were weighed against the potential number of healthy years of life saved. The results are consistent with earlier studies that suggest that tobacco control is highly cost- effective as part of a basic public health package in low- and middle-income countries. Measured in terms of the cost per year of healthy life saved, tax increases would be cost-effective. Depending on various assumptions, this instrument could cost between US$5 and $17' for each year of healthy life saved in low- and middle-income countries. This compares favorably with many health in- terventions commonly financed by governments, such as child immunization. Nonprice measures are also cost-effective in many settings. Measures to liber- alize access to nicotine replacement therapy, for example, by changing the conditions for its sale, would probably also be cost-effective in most settings. However, individual countries would need to make careful assessments before deciding to provide subsidies for NRT and other cessation interventions for poor smokers. The unique potential of tobacco taxation to raise revenues cannot be ig- nored. In China, for example, conservative estimates suggest that a 10 percent 10 CURBING THE EPIDEMIC increase in cigarette tax would decrease consumption by 5 percent, increase revenue by 5 percent, and that the increase would be sufficient to finance a package of essential health services for one-third of China's poorest 100 mil- lion citizens. All agenda for action Each society makes its own decisions about policies that concern individual choices. In reality, most policies would be based on a mix of criteria, not only economic ones. Most societies would wish to reduce the unquantifiable suffer- ing and emotional losses wrought by tobacco's burden of disease and prema- ture death. For the policymaker seeking to improve public health, too, tobacco control is an attractive option. Even modest reductions in a disease burden of such large size would bring highly significant health gains. Some policymakers will consider that the strongest grounds for interven- ing are to deter children from smoking. However, a strategy aimed solely at deterring children is not practical and would bring no significant benefits to public health for several decades. Most of the tobacco-related deaths that are projected to occur in the next 50 years are among today's existing smokers. Governments concerned with health gains in the medium term may therefore consider adopting broader measures that also help adults to quit. The report has two recommendations: 1. Where governments decide to take strong action to curb the tobacco epidemic, a multi-pronged strategy should be adopted. Its aims should be to deter children from smoking, to protect nonsmokers, and to provide all smokers with information about the health effects of to- bacco. The strategy, tailored to individual country needs, would in- clude: (1) raising taxes, using as a yardstick the rates adopted by countries with comprehensive tobacco control policies where con- sumption has fallen. In these countries, tax accounts for two-thirds to four-fifths of the retail price of cigarettes; (2) publishing and dis- seminating research results on the health effects of tobacco, adding prominent warning labels to cigarettes, adopting comprehensive bans on advertising and promotion, and restricting smoking in workplaces and public places; and (3) widening access to nicotine replacement and other cessation therapies. 2. International organizations such as the UN agencies should review their existing programs and policies to ensure that tobacco control is given due prominence; they should sponsor research into the causes, consequences, and costs of smoking, and the cost-effectiveness of in- terventions at the local level; and they should address tobacco control SUMMARY 1 1 issues that cross borders, including working with the WHO's proposed Framework Convention for Tobacco Control. Key areas for action in- clude facilitating international agreements on smuggling control, dis- cussions on tax harmonization to reduce the incentives for smuggling, and bans on advertising and promotion involving the global commu- nications media. The threat posed by smoking to global health is unprecedented, but so is the potential for reducing smoking-related mortality with cost-effective poli- cies. This report shows the scale of what might be achieved: moderate action could ensure substantial health gains for the 21st century. Note 1. All dollar amounts are current U.S. dollars. CHAPTER 1 Global Trends in Tobacco Use ALTHOUGH people have used tobacco for centuries, cigarettes did not appear in mass-manufactured form until the 19th century. Since then, the practice of cigarette smoking has spread worldwide on a massive scale. Today, about one in three adults, or 1.1 billion people, smoke. Of these, about 80 percent live in low- and middle-income countries. Partly because of growth in the adult population, and partly because of increased consumption, the total number of smokers is expected to reach about 1.6 billion by 2025. In the past, tobacco was often chewed, or smoked in various kinds of pipes. While these practices persist, they are declining. Manufactured ciga- rettes Oand various types of hand-rolled cigarette such as bidis-common in southeast Asia and India-now account for up to 85 percent of all tobacco consumed worldwide. Cigarette smoking appears to pose much greater dan- gers to health than earlier forms of tobacco use. This report therefore focuses on manufactured cigarettes and bidis. Rising consumption in low-income and middle-income countries The populations of the low- and middle-income countries have been increas- ing their cigarette consumption since about 1970 (see Figure 1.1). The per capita consumption in these countries climbed steadily between 1970 and 1990, although the upward trend may have slowed a little since the early 1990s. 13 14 CURBING THE EPIDEMIC FIGURE 1.1 SMOKING IS INCREASING IN THE DEVELOPING WORLD Trends in per capita adult cigarette consumption 3000 250 o % 2000 Delod _ U ~~~~~~~~~~~~~~~Developing B 1500Wol 1000 500 1970-72 1980-82 1990-92 Year Source: World Health Organization. 1997. Tobacco or Health: a Global Status Report. Geneva, Switzerland. While the practice of smoking has become more prevalent among men in low- and middle-income countries, it has been in overall decline among men in the high-income countries during the same period. For example, more than 55 percent of men in the United States smoked at the peak of consumption in the mid-20th century. but the proportion had fallen to 28 percent by the mid- 1990s. Per capita consumption for the populations of the high-income coun- tries as a whole also has dropped. However, among certain groups in these countries, such as teenagers and young women, the proportion who smoke has grown in the 1990s. Overall, then, the smoking epidemic is spreading from its original focus, among men in high-income countries, to women in high-in- come countries and men in low-income regions. In recent years, international trade agreements have liberalized global trade in many goods and services. Cigarettes are no exception. The removal of trade barriers tends to introduce greater competition that results in lower prices, greater advertising and promotion, and other activities that stimulate demand. One study concluded that, in four Asian economies that opened their markets in response to U.S. trade pressure during the 1980s-Japan, South Korea, Tai- wan, and Thailand-consumption of cigarettes per person was almost 10 per- cent higher in 1991 than it would have been if these markets had remained closed. An econometric model developed for this report concludes that in- GLOBAL TRENDS IN TOBACCO USE 15 creased trade liberalization contributed significantly to increases in cigarette consumption, particularly in the low- and middle-income countries. Regional patterns in smoking Data on the number of smokers in each region have been compiled by the World Health Organization using more than 80 separate studies. For the pur- pose of this report, these data have been used to estimate the prevalence of smoking in each of the seven World Bank country groupings.' As Table 1.1 shows, there are wide variations between regions and, in particular, in the preva- lence of smoking among women in different regions. For example, in Eastem Europe and Central Asia (mainly the former socialist economies), 59 percent of men and 26 percent of women smoked in 1995, more than in any other region. Yet in East Asia and the Pacific, where the prevalence of male smoking is equally high, at 59 percent, just 4 percent of women were smokers. Smoking and socioeconomic status Historically, as incomes rose within populations, the number of people who smoked rose too. In the earlier decades of the smoking epidemic in high-in- come countries, smokers were more likely to be affluent than poor. But in the TABLE 1.1 REGIONAL PATTERNS OF SMOKING Estimated smoking prevalence by gender and number of smokers in population aged 15 or more, by World Bank region, 1995 Total smoker-s World Bank Smoking prevalence (%) (% of all Region Males Females Overall (inillions) smokers) East Asia and Pacific 59 4 32 401 35 Eastern Europe and Central Asia 59 26 41 148 13 Latin America and Caribbean 40 21 30 95 8 Middle East and North Africa 44 5 25 40 3 South Asia (cigarettes) 20 1 11 86 8 South Asia (bidis) 20 3 12 96 8 Sub-Saharan Africa 33 10 21 67 6 Low/Middle Income 49 9 29 933 82 High Income 39 22 30 209 18 World 47 12 29 1,142 100 Note:Numbers have been rounded.

Geneva, Switzerland. 16 CURBING THE EPIDEMIC past three to four decades, this pattern appears to have been reversed, at least among men, for whom data are widely available.' Affluent men in the high- income countries have increasingly abandoned tobacco, whereas poorer men have not done so. For example, in Norway, the percentage of men with high incomes who smoked fell from 75 percent in 1955 to 28 percent in 1990. Over the same period, the proportion of men on low incomes who smoked declined much less steeply, from 60 percent in 1955 to 48 percent in 1990. Today, in most high-income countries, there are significant differences in the prevalence of smoking between different socioeconomic groups. In the United Kingdom, for instance, only 10 percent of women and 12 percent of men in the highest socioeconomic group are smokers; in the lowest socioeconomic groups the corresponding figures are threefold greater: 35 percent and 40 percent. The same inverse relationship is found between education levels-a marker for socioeconomic status -and smoking. In general, individuals who have received little or no education are more likely to smoke than those who are more edu- cated. Until recently, it was thought that the situation in low- and middle-income countries was different. However, the most recent research concludes that here too, men of low socioeconomic status are more likely to smoke than those of high socioeconomic status. Educational level is a clear determinant of smok- ing in Chennai, India (Figure 1.2). Studies in Brazil, China, South Africa, Viet- nam, and several Central American nations confirm this pattern. While it is thus clear that the prevalence of smoking is higher among the poor and less educated worldwide, there are fewer data on the n umber of ciga- rettes smoked daily by different socioeconomic groups. In high-income coun- tries, with some exceptions, poor and less educated men smoke more cigarettes per day than richer, more educated men. While it might have been expected that poor men in low- and middle-income countries would smoke fewer ciga- rettes than affluent men, the available data indicate that, in general, smokers with low levels of education consume equal or slightly larger numbers of ciga- rettes than those with high levels of education. An important exception is In- dia, where, not surprisingly, smokers with college-level education status tend to consume more cigarettes, which are relatively more expensive, while smok- ers with low levels of education status consume larger numbers of the inexpen- sive bidis. Age and the uptake of smoking It is unlikely that individuals who avoid starting to smoke in adolescence or young adulthood will ever become smokers. Nowadays, the overwhelming majority of smokers start before age 25, often in childhood or adolescence (see Box 1.1 and Figure 1.3); in the high-income countries, eight out of 10 GLOBAL TRENDS IN TOBACCO USE 17 FIGURE 1.2 SMOKING IS MORE COMMON AMONG THE LESS EDUCATED Smoking prevalence among men in Chennai (India) by education levels 64% 58% 60% 42% vv 40% 0) o0 21% E 20% 0% Illiterate <6 years 6-12 >12 years years Length of schooling Source: Gajalakshmi, C.

In middle-income and low-income countries for which data are available, it appears that most smokers start by the early twenties, but the trend is toward younger ages. For example, in China between 1984 and 1996, there was a significant increase in the number of young men aged be- tween 15 and 19 years who took up smoking. A similar decline in the age of starting has been observed in the high-income countries. Global patterns of quitting While there is evidence that smoking begins in youth worldwide, the propor- tion of smokers who quit appears to vary sharply between high-income coun- tries and the rest of the world, at least to date. In environments of steadily 18 CURBING THE EPIDEMIC FIGURE 1.3 SMOKING STARTS EARLY IN LIFE Cumulative distribution of smoking initiation age in China, India, and the United States United States (both sexes, 100 born 1952-61) China (males, 1996) United States 80 (both sexes, CD , .h. = ~^born 1910-14) India (males, 1995) Co 60 20 E 0 1 5 20 25 Age Sources: Chinese Academy of Preventive Medicine. 1997.

In most high-income countries, about 30 per- cent of the male population are former smokers. In contrast, only 2 percent of Chinese men had quit in 1993, only 5 percent of Indian males at around the same period, and only 10 percent of Vietnamese males had quit in 1997.

Research into women's smoking patterns is much more limited. Where women have been smoking for decades, the relationship between socioeconomic status and smok- ing is similar to that seen in men, Elsewhere, more reliable information is needed before conclusions can be drawn. CHAPTER 2 The Health Consequences of Smoking THE impact of tobacco on health has been extensively documented. This report does not seek to repeat this information in detail but simply to summarize the evidence. The section is divided into two parts: first, a brief discussion of nicotine addiction; and second, a description of the disease bur- den attributable to tobacco. The addictive nature of tobacco smoking Tobacco contains nicotine, a substance that is recognized to be addictive by intemational medical organizations. Tobacco dependence is listed in the Inter- national Classification of Diseases. Nicotine fulfills the key criteria for addic- tion or dependence, including compulsive use, despite the desire and repeated attempts to quit; psychoactive effects produced by the action of the substance on the brain; and behavior motivated by the "reinforcing" effects of the psycho- active substance. Cigarettes, unlike chewed tobacco, enable nicotine to reach the brain rapidly, within a few seconds of inhaling smoke, and the smoker can regulate the dose puff by puff. Nicotine addiction can be established quickly. In young adolescents who have recently taken up smoking, saliva concentrations of cotinine, a breakdown product of nicotine, climb steeply over time toward the levels found in estab- lished smokers (Figure 2.1). The average levels of nicotine inhaled are suffi- cient to have a pharmacological effect and to play a role in reinforcing smoking. Yet many young smokers underestimate their risks of becoming addicted. Be- tween half and three-quarters of young smokers in the United States say they have tried to quit at least once and failed. Surveys in the high-income countries 21 22 CURBING THE EPIDEMIC FIGURE 2.1 NICOTINE LEVELS CLIMB RAPIDLY IN YOUNG SMOKERS Saliva concentrations of cotinine in a group of adolescent girls in the United Kingdom 250 200 - Smokers in E ~~~~~~~~~~~~~1985 06) / , ' ----- Not smokers in (,100 1985; became ,lt smokers in 50 - , 1986-1987 0 1985 1986 1987 Year Source: McNeill, A.

American Journal of Public Health 79(2): 172-75. suggest that a substantial proportion of smokers as young as 16 regret their use of cigarettes but feel unable to stop. It is of course possible to abstain permanently, as is the case with other addictive substances. However, without cessation interventions, the individual success rates are low. The most recent research concludes that, of regular smok- ers who try to quit unaided, 98 percent will have started again within a year. The disease burden Within the next year, tobacco is expected to kill approximately 4 million people worldwide. Already, it is responsible for one in 10 adult deaths; by 2030 the figure is expected to be one in six, or 10 million deaths each year-more than any other cause and more than the projected death tolls from pneumonia. diar- rheal diseases, tuberculosis, and the complications of childbirth for that year combined. If current trends persist, about 500 million people alive today will eventually be killed by tobacco, half of them in productive middle age, losing 20 to 25 years of life. THE HEALTH CONSEQUENCES OF SMOKING 23 Smoking-related deaths, once largely confined to men in the high-income countries, are now spreading to women in high-income countries and men throughout the world (Table 2.1). Whereas in 1990 two out of every three smoking-related deaths were in either the high-income countries or the former socialist states of Eastern Europe and Central Asia, by 2030, seven out of ev- ery 10 such deaths will be in low- and middle-income countries. Of the half- billion deaths expected among people alive today, about 100 million will be in Chinese men. Long delays between exposure and disease However, the toll of death and disability from smoking outside the high-in- come countries has yet to be felt. This is because the diseases caused by smok- ing can take several decades to develop. Even when smoking is very common in a population, the damage to health may not yet be visible. This point can be most clearly demonstrated by trends in lung cancer in the United States. While the most rapid growth in cigarette consumption in the United States happened between 1915 and 1950, rates of lung cancer did not begin to rise steeply until about 1945. Age-standardized rates of the disease trebled between the 1930s and 1950s, but after 1955 the rates increased much more: by the 1980s, rates were Il-fold higher than levels in 1940. In China today, where one-quarter of the world's smokers live, cigarette consumption is as high as it was in the United States in 1950, when per capita consumption levels were reaching their peak. At that stage of the U.S. epi- demic, tobacco was responsible for 12 percent of all the nation's deaths in middle age. Forty years later, when cigarette consumption in the United States was already in decline, tobacco was responsible for about one-third of the nation's middle-aged deaths. Today, in a striking echo of the U.S. experience, tobacco is estimated to be responsible for about 12 percent of male middle- aged deaths in China. Researchers expect that within a few decades, the pro- portion there will rise to about one in three, as it did in the United States.

Geneva, Swit- zerland. 24 CURBING THE EPIDEMIC contrast, smoking among young Chinese women has not increased markedly in the past two decades, and most of those women who do smoke are older. Thus, on current smoking patterns, female tobacco-attributable deaths in China may actually drop from their current level of about 2 percent of the total to less than I percent. Even in the high-income countries whose populations have been exposed to smoking for many decades, a clear picture of tobacco-related diseases has taken at least 40 years to emerge. Researchers calculate the excess risk of death in smokers through prospective studies that compare the health outcomes of smokers and nonsmokers. After 20 years of follow-up, in the early 1970s, researchers believed that smokers faced a one-in-four risk of being killed by tobacco, but now, with more data, they believe that the risk is one in two. How smoking kills In the high-income countries, long-term prospective studies such as the Ameri- can Cancer Society's Second Cancer Prevention study, which followed more than I million U.S. adults, have provided reliable evidence of how smoking kills. Smokers in the United States are 20 times more likely to die of lung cancer in middle age than nonsmokers and three times more likely to die in middle age of vascular diseases, including heart attacks, strokes, and other diseases of the arteries or veins. Because ischemic heart disease is common in high-income countries, the smoker's excess risk translates into a very large number of deaths, making heart disease the most common smoking-related cause of death in these countries. Smoking is also the leading cause of chronic bronchitis and emphysema. It is associated with cancers of various other or- gans, including the bladder, kidney, larynx, mouth, pancreas, and stomach. A person's risk of developing lung cancer is affected more strongly by the amount of time that they have been a smoker than by the number of cigarettes they have smoked daily. Put differently, a threefold increase in the duration of smoking is associated with a 100-fold risk of lung cancer, whereas a threefold increase in the number of cigarettes smoked each day is associated with only a threefold risk of lung cancer. Thus those who start to smoke in their teens and who continue face the biggest risks. For some years, cigarette manufacturers have marketed certain brands as "low tar" and "low nicotine," a modification that many smokers believe makes cigarettes safer. However, the difference in the risk of premature death for smokers of low-tar or low-nicotine brands compared with smokers of ordi- nary cigarettes is far less than the difference in risk between nonsmokers and smokers. The epidemic varies in place as well as in time THE HEALTH CONSEQUENCES OF SMOKING 25 Because most long-term studies have been confined to the high-income coun- tries, data on the health effects of tobacco elsewhere have been scant. However,recent major studies from China, and emerging studies from India, indicate that although the overall risks of persistent smoking are about as great as in high-income countries such as the United States and the United King- dom, the pattern of smoking-related diseases in these nations is substantially different. The data from China suggest that deaths from ischemic heart disease make up a much smaller proportion of the total number of deaths caused by tobacco than in the West, while respiratory diseases and cancers account for most of the deaths. Strikingly, a significant minority involve tuberculosis. Other differences may emerge in other populations; for instance, in South Asia, the pattern may be affected by a high underlying prevalence of cardiovascular disease. These results underscore the importance of monitoring the epidemic in all regions. Nevertheless, despite the different patterns of smoking-related disease in different populations, it appears that the overall proportion who are eventually killed by persistent cigarette smoking is generally about one in two in many populations. Smoking and the health disadvantage of the poor As tobacco use is associated with poverty and low socioeconomic status, so are its damaging effects on health. Analyses for this report show the impact of smoking on the survival of men in different socioeconomic groups (measured by income, social class, or educational level) in four countries where the smok- ing epidemic is mature-Canada, Poland, the United Kingdom, and the United States. In Poland in 1996 men with a university education had a 26 percent risk of death in middle age. For men with only primary-level education, the risk was 52 percent-twice as great. By analyzing the proportion of deaths due to smok- ing in each group, researchers estimate that tobacco is responsible for about two-thirds of the excess risk in the group with only primary-level education. In other words, if smoking were eliminated, the survival gap between the two groups would narrow sharply. The risk of death in middle age would fall to 28 percent in men with only primary-level education and 20 percent in those with university education (Figure 2. 2) . Similar results emerge from the other coun- tries in the study, indicating that tobacco is responsible for more than half of the difference in adult male mortality between those of highest and lowest socioeconomic status in these countries. Smoking has also contributed heavily to the widening of the survival gap over time between affluent and disadvan- taged men in these countries (Figure 2.3). The risks from others' smoke 26 CURBING THE EPIDEMIC FIGURE 2.2 EDUCATION AND THE RISK OF SMOKING- ATTRIBUTABLE DEATH Deaths in middle-aged males of different education levels, Poland 1996 60% 500/ 4 Other causes 40% g28% 3 Attributed to smoking but 30% would have died anyway at U 30% $9-y =,i, W ages 35-69 l 20% -2% * Attributed to smoking 10% 0% Higher Secondary Primary Education level Note: Numbers have been rounded.

Women who smoke during pregnancy are more likely to lose the fetus through spontaneous abortion. Babies born to smoking mothers in high-income coun- tries are significantly more likely than the babies of nonsmokers to have a low birth weight and up to 35 percent more likely to die in infancy. They also face higher risks of respiratory disease. Recent research has shown that a carcino- gen found only in tobacco smoke is present in the urine of newborn babies born to smokers. Cigarette smoking accounts for much of the health disadvantage of babies born to poorer women. Among white women in the United States, smoking alone has been found to be responsible for 63 percent of the difference in birth weight between babies born to college-educated women and babies born to those who received a high school education or less. Adults exposed chronically to others' tobacco smoke also face small but real risks of lung cancer and higher risks of cardiovascular disease, while the children of smokers suffer a range of health problems and functional limita- tions.

Poverty and Tobacco. Back- ground paper. Nonsmokerswho are exposed to smoke include the children and the spouses of smokers, mostly within their own homes. Also, a substantial number of nonsmokers work with smokers, or in smoky environments, where their expo- sure over time is significant. Quitting works The earlier a smoker starts, the greater the risk of disabling illnesses. In high- income countries with long-term data, researchers have concluded that smok- ers who start early and smoke regularly are much more likely to develop lung cancer than smokers who quit while they are still young. In the United Kingdom, male doctors who stop smoking before the age of 35 survive about as well as those who never smoked. Those who quit between the ages of 35 and 44 also gain substantial benefits, and there are benefits at older ages, too. 28 CURBING THE EPIDEMIC In sum, then, the epidemic of smoking-related disease is expanding from its original focus in men in high-income countries to affect women in high- income countries and men in low- and middle-income countries. Smoking is increasingly associated with social disadvantage, as measured by income and educational levels. Most new smokers underestimate the risk of becoming ad- dicted to nicotine; by early adulthood, many regret starting to smoke and feel unable to stop. Half of long-term smokers will eventually be killed by tobacco, and half of these will die in middle age. CHAPTER 3 Do Smokers Know Their Risks and Bear Their Costs? IN this chapter, we examine the incentives for people to smoke. We consider whether smoking is like other consumption choices, and whether it results in an efficient allocation of society's resources. We then discuss the implications for governments. Modem economic theory holds that individual consumers are the best judges of how to spend their money on goods such as rice, clothing, or movies. This principle of consumer sovereignty is based on certain assumptions: first, that each consumer makes rational and informed choices after weighing the costs and benefits of purchases, and, second, that the consumer incurs all costs of the choice. When all consumers exercise their sovereignty in this way- knowing their risks and bearing the costs of their choices-then society's re- sources are, in theory, allocated as efficiently as possible. Smokers clearly perceive benefits from smoking; otherwise they would not pay to do it. The perceived benefits include pleasure and satisfaction, enhanced self-image, stress control and, for the addicted smoker, the avoidance of nicotine withdrawal. The private costs to be weighed against those benefits include money spent on tobacco products, damage to health, and nicotine addiction. Defined this way, the perceived benefits evidently outweigh the perceived costs. However, the choice to buy tobacco products differs in three specific ways from the choice to buy other consumer goods: * First, there is evidence that many smokers are not fully aware of the high probability of disease and premature death that their choice en- tails. This is the major private cost of smoking. 29 30 CURBING THE EPIDEMIC * Second, there is evidence that children and teenagers may not have the capacity to properly assess any information that they possess about the health effects of smoking. Equally important, there is evidence that new recruits to smoking may seriously underestimate the future costs associated with addiction to nicotine. These future costs may be thought of as the costs for adult smokers of being unable to alter a youthful decision to smoke, even if desired, because of addiction. * Third, there is evidence that smokers impose costs on other indi- viduals, both directly and indirectly. Economists usually assume that individuals properly weigh the costs and benefits of their choices only when they themselves incur these costs and enjoy these ben- efits. If others bear some of the costs, it follows that smokers may smoke more than they would if they were bearing all the costs them- selves. We consider the evidence for each of these in tum. Awareness of the risks People's knowledge of the health risks of smoking appears to be partial at best, especially in low- and middle-income countries where information about these hazards is limited. In China, for example, 61 percent of adult smokers surveyed in 1996 believed that cigarettes did them "little or no harm." In the high-income countries, general awareness of the health effects of smoking has undoubtedly increased over the past four decades. How- ever, there has been much controversy about how accurately smokers in high-income countries perceive their risks of developing disease. Various studies conducted over the past two decades have produced mixed conclu- sions about the accuracy of individuals' perceptions of the risks from smok- ing. Some find that people overstate these risks, others find that the risks are underestimated, and still others find that risk perceptions are adequate. The methodologies employed in these studies, however, have been criti- cized on multiple grounds. An overview of the research literature recently concluded that smokers in high-income countries are generally aware of their increased risks of disease, but that they judge the size of these risks to be smaller and less well-established than do nonsmokers. Moreover, even where individuals have a reasonably accurate perception of the health risks faced by smokers as a group, they minimize the personal relevance of this information, believing other smokers' risks to be greater than their own. Finally, there is evidence from various countries that some smokers may have a distorted perception of the health risks of smoking compared with other health risks. For example, in Poland in 1995 researchers asked DO SMOKERS KNOW THEIR RISKS AND BEAR THE COSTS? 31 adults to rate "the most important factors influencing human health." The factor most frequently chosen was "the environment," followed by "di- etary habits" and "stress or hectic lifestyles." Smoking trailed in fburth place, and was mentioned by only 27 percent of adults questioned. In fact, smoking accounts for more than one-third of the risk of premature death in middle-aged men in Poland, far more than any other risk factor. Youth, addiction, and the capacity to make sound decisions As stated in chapter 1, most smoking starts early in life, and children and teenagers may know less about the health effects of smoking than adults. A recent survey of 15- and 16-year-olds in Moscow found that more than half either knew of no smoking-related diseases or could name only one, lung can- cer. Even in the United States, where young people might be expected to have received more information, almost half of 1 3-year-olds today think that smok- ing a pack of cigarettes a day will not cause them great harm. Given adoles- cents' inadequate knowledge, they face greater obstacles than adults in making informed choices. Equally important, young people underestimate the risk of becoming ad- dicted to nicotine, and therefore grossly underestimate their future costs from smoking. Among final-year high school students in the United States who smoke but believe they will quit within five years, fewer than two out of five actually do quit. The rest are still smoking five years later. In high-income countries, about seven out of 10 adult smokers say they regret their choice to start smok- ing. Using econometric models of the relationship between current smoking and past smoking, based on U.S. data, researchers estimate that addiction to nicotine accounts for at least 60 percent of the cigarette consumption in any one year, and possibly as much as 95 percent. Even teenagers who have been told about the risks of smoking may have a limited capacity to use the information wisely. It is difficult for most teen- agers to imagine being 25, let alone 55, and warnings about the damage that smoking will inflict on their health at some distant date are unlikely to re- duce their desire to smoke. The risk that young people will make unwise decisions is recognized by most societies and is not unique to choices about smoking. Most societies restrict young people's power to make certain deci- sions, although these vary from culture to culture. For example, most de- mocracies prevent their young people from voting before a certain age; some societies make education compulsory up to a certain age; and many prevent marriage before a certain age. The consensus across most societies is that some decisions are best left until adulthood. Likewise, societies may con- sider that the freedom of young people to choose to become addicted should be restricted. 32 CURBING THE EPIDEMIC It might be argued that young people are attracted to many risky behaviors, such as fast driving or alcohol binge-drinking, and that there is nothing special about smoking. However, there are several differences. First, for most of the world, smoking is less heavily regulated than other risky behaviors. Drivers are usually penalized for excessive speed with heavy fines and even loss of license, and there are penalties for dangerous behavior associated with heavy drinking, such as drunk driving. Second, smoking is much more dangerous than most risky activities over a lifetime. Extrapolations based on data from high-income countries suggest that, of 1,000 15-year-old males currently living in low- and middle-income countries, 125 will be killed by smoking in middle age if they continue to smoke regularly, with an additional 125 in old age. By comparison, about 10 will die in middle age due to road accidents, about 10 will die in middle age because of violence, and about 30 will die in middle age of alcohol- related causes, including some road accidents and violent deaths. Third, few other risky behaviors carry the high risk of addiction that is seen with smoking, so most are easier to abandon, and are abandoned, in maturity. Costs imposed on others Smokers impose physical costs on others as well as possible financial costs. In theory, smokers would smoke less if they took these costs into account, be- cause the socially optimal level of consumption, in which resources are effi- ciently distributed in society, is reached when all costs are borne by the consumer. If part of the costs are borne by nonsmokers, then cigarette con- sumption may be higher than socially optimal. We now briefly discuss the various types of costs imposed on others. First, smnokers impose direct health costs on nonsmokers. The health ef- fects, described in chapter 2, include low birth weight and increased risk of various diseases in the infants of smoking mothers, and disease in children and adults chronically exposed to second-hand smoke. Other direct costs include irritation and nuisance from smoke and the cost of cleaning clothes and fur- nishings. Although evidence is much more patchy, there may also be a cost from fires, environmental degradation, and deforestation from tobacco grow- ing and processing, and from the consequences of smoking. Given existing data, the financial costs that smokers impose on others are difficult to identify and quantify. This report does not attempt to provide an estimate of these costs, but instead it describes some of the main areas in which such costs can arise. We first discuss the cost of healthcare for smokers, then the issue of pensions. In high-income countries, the overall annual cost of healthcare that may be attributed to smoking has been estimated to be between 6 and 15 percent of total healthcare costs. In most low- and middle-income countries today, the DO SMOKERS KNOW THEIR RISKS AND BEAR THE COSTS? 33 annual costs of healthcare attributable to smoking are lower than this, partly because the epidemic of tobacco-related diseases is at an earlier stage, and partly because of other factors such as the kinds of tobacco-related diseases that are most prevalent and the treatments that they require. However, these countries are likely to see their annual smoking-related healthcare costs rise in the future. Projections performed for this report for China and India suggest that the annual costs of healthcare for smoking-related disease will grow to absorb a larger percentage of gross domestic product (GDP) than today. For policymakers, it is vital to know these annual healthcare costs and the fraction borne by the public sector, because they represent real resources that cannot be used for other goods and services. For individual consumers, on the other hand, the key issue is the extent to which the costs will be borne by themselves or by others. Again, if some of the costs are likely to be borne by nonsmokers, consumers have an incentive to smoke more than they would if they were expecting to bear all the costs themselves. As the following discus- sion shows, however, the assessment of these costs is complex, and therefore it is not yet possible to conclude anything about how they may influence smok- ers' consumption choices. In any given year, on average, a smoker's healthcare is likely to cost more than that of a nonsmoker of the same age and sex. However, because smokers tend to die earlier than nonsmokers, the lifetinme healthcare costs of smokers and nonsmokers in high-income countries may be fairly similar. Studies that measure the lifetime healthcare costs of smokers and nonsmokers in the high- income countries have reached conflicting conclusions. In the Netherlands and Switzerland, for example, smokers and nonsmokers have been found to have similar costs, while in the United Kingdom and the United States some studies have concluded that smokers' lifetime costs are in fact higher. Recent reviews that take account of the growing number of tobacco-attributable dis- eases and other factors conclude that, overall, smokers' lifetime costs in high- income countries are somewhat greater than those of nonsmokers, despite their earlier deaths. There are no such reliable studies on lifetime healthcare costs in low-income and middle-income countries. Clearly, for all regions of the world, smokers who bear the full costs of their medical services will not be imposing costs on others, however much greater those costs may be than nonsmokers'. But much medical care, espe- cially that associated with hospital treatment, is financed either through gov- ernment budgets or through private insurance. To the extent that contributions to either of these financing mechanisms-in the form of taxes and insurance premiums-are not differentially higher for smokers, the higher medical costs attributable to smokers will be at least partly borne by nonsmokers. For example, in high-income countries, public expenditure on health ac- counts for about 65 percent of all health expenditures, or about 6 percent of 34 CURBING THE EPIDEMIC GDP. Thus, if smokers have higher net lifetime healthcare costs, then non- smokers will subsidize the healthcare costs of smokers. The exact contribu- tion is complex and variable, depending on the type of coverage, and the source of taxation that is used to pay for public expenditures. If, for example, only the healthcare costs of those over 65 are publicly funded, then the net use of public revenues by smokers may be small, to the extent that many require smoking-related medical care and die before they reach this age. Equally, if public expenditures are financed out of consumption taxes, in- cluding cigarette taxes, then smokers may not be imposing costs on others. Once again, the situation differs in low- and middle-income countries, where the public component of total healthcare expenditure is on average lower than in high-income countries, at around 44 percent of the total, or 2 percent of GDP. However, as countries spend more on health, the share of total expendi- ture that is met by public finance tends to rise too. While it is thus a complex issue to assess the relative healthcare costs of smokers and nonsmokers, the issue of pensions has proved at least as conten- tious. Some analysts have argued that smokers in high-income countries con- tribute more than nonsmokers to public pension schemes, because many pay contributions until around retirement age and then die before they can claim a substantial proportion of their benefits.' However, a quarter of regular smok- ers are killed by tobacco in middle age, and may therefore die before they have paid their full pension contributions. At present, it is not known whether, over- all, smokers in high-income countries do contribute more or less to public pensions than nonsmokers. However, the issue is not currently relevant to many of the low-income and middle-income countries. In low-income countries only about one in 10 adults has a public pension, and in middle-income countries the proportion is between a quarter and half of the population, depending on the income level of the individual country. In sum, smokers clearly impose direct costs, such as health damage, on nonsmokers. There are probably also financial costs, for example in healthcare, although they are more difficult to identify or quantify. Appropriate responses for governments Given the three problems we identify, it appears unlikely that most smokers either know the full extent of their risks or bear all of the costs of their choice. Thus, their consumption choices may result in inefficient allocation of resources. Governments may therefore be justified in intervening to adjust the incentives to consumers so that they smoke less. Societies may consider that the strongest reason for governments to inter- vene is to deter children and adolescents from smoking, given the compound problem of their inadequate access to info, rnation about tobacco, their risk of DO SMOKERS KNOW THEIR RISKS AND BEAR THE COSTS? 35 becoming addicted, and their limited ability to make sound decisions. Govern- ments also have a justification for intervening to prevent smokers from impos- ing direct physical costs on nonsmokers. The justification for protecting others from smokers' financial costs is less strong, as the nature of those costs re- mains unclear. Finally, some societies would consider that there is a role for government in providing adults with all the information they need to make informed consumption choices. Ideally, government interventions should address each identified problem with a specific intervention. However, this is not always possible and some interventions may have broader effects. Thus, for example, children's and ado- lescents' imperfect judgments about the health effects of smoking would most specifically be addressed by improving their education about those effects, and by improving their parents' education. However, in reality, children re- spond poorly to health education and parents are imperfect agents, not always acting in their children's best interests. In reality, taxation-albeit a blunt in- strument-is the most effective and practical method of deterring children and adolescents from smoking. Evidence from a number of studies shows that chil- dren and adolescents are less likely to take up smoking, and that their smoking peers are more likely to quit, if the price of cigarettes rises. The most specific measure to protect nonsmokers would be the imposi- tion of restrictions on where individuals may smoke. While this would pro- tect nonsmokers in public places, it would not reduce the substantial exposure to others' smoke in the home. Thus taxes would be an additional method of making smokers bear the costs that they impose on nonsmokers. To address the problem of the financial costs imposed on nonsmokers, such as any excess cost of healthcare for smokers, the most direct mechanism would be to make healthcare financing systems reflect individuals' smoking behavior: thus, for example, smokers should pay higher premiums than non- smokers, or be required to open healthcare savings accounts that reflect their likely higher costs. In practice, an easier way to make smokers contribute more would be to levy a tobacco tax. In theory, if cigarette taxes are to be used to deter children and adoles- cents from smoking, then the tax on children should be higher than the tax on adults. Such differential tax treatment would, however, be virtually impossible to implement. Yet a uniform rate for children and adults, the more practical option, would impose a burden on adults. Societies may nevertheless consider that it is justifiable to impose this burden on adults in order to protect children. Moreover, if adults reduce their cigarette consumption, children may smoke less too, given evidence that children's propensity to smoke is influenced by whether their parents, and other adult role models, smoke. One way to implement a differential tax system for children and adults would be to restrict children's access to cigarettes. In theory, such restrictions 36 CURBING THE EPIDEMIC would effectively increase the price that children must pay for tobacco, with- out affecting the price paid by adults. In practice, however, there is little evi- dence that existing restrictions work in high-income countries. In low- and middle-income countries, where the capacity to administer and enforce such restrictions is likely to be less, they would be even more difficult to imple- ment. Therefore, to deter children from smoking, the second-best instrument, higher taxes, is favored. Dealing with addiction In addition to the need to correct for the inefficiencies that arise from smokers' consumption choices, there is the need to address the problem of addiction. Because of addiction, adult smokers are faced with high costs if they want to reverse decisions that were largely made in youth. Societies may choose to provide interventions that would help would-be quitters to reduce these costs. These interventions include increased access to information that will alert the smoker to the costs of continuing to smoke and the benefits of quitting, and wider access to cessation therapies that would lower the costs of quitting. Clearly, increased taxation may induce some smokers to quit, but it will also impose costs on them. These costs will be the lost perceived benefits of smok- ing and additional physical costs associated with withdrawal from their addic- tion. Policymakers could reduce the costs by widening smokers' access to cessation therapies. We discuss the question of withdrawal costs further in chapter 6. For children who have not yet become addicted to nicotine, mean- while, taxation would be an effective strategy because there would be no with- drawal costs associated with the decision not to smoke. We turn now to consider some interventions that have already been adopted by some governments to control tobacco. Each of these interventions is evalu- ated in turn. In chapter 4, we discuss measures intended to reduce the demand for tobacco, and in chapter 5 we evaluate measures intended to reduce its supply. Note 1. Even if smokers reduce the net costs imposed on others by dying young, it would be misleading to suggest that society is better off because of these premature deaths. To do so would be to accept the logic that says society is better off without its older adults. CHAPTER 4 Measures to Reduce the Demand for Tobacco COUNTRIES with successful tobacco control policies employ a mix of approaches. We now discuss each in turn, summarizing the evidence for their effectiveness. Raising cigarette taxes For centuries, tobacco has been considered an ideal consumer good for taxation: it is not a necessity, it is consumed widely, and demand for it is relatively inelastic, so it is likely to be a reliable and easily administered source of government revenue. Adam Smith, writing in Wealth of Nations in 1776, suggested that, through such a tax, the poor "might be relieved from some of the most burdensome taxes; from those which are imposed either upon the necessaries of life, or upon the materials of manufacture." A tobacco tax, Smith argued, would allow poor people to "live better, work cheaper, and to send their goods cheaper to market."' Demand for their work would increase, in turn raising the incomes of poor people and benefit- ing the entire economy. Two centuries later, almost all governments tax tobacco, sometimes heavily, by a variety of different methods. Their motives have almost always been to gen- erate revenue, but in more recent years taxes have also reflected an increasing concern with the need to minimize the health damage of smoking. 37 38 CURBING THE EPIDEMIC This section reviews the evidence on how increased taxation affects the de- mand for cigarettes and other tobacco products. It concludes that raising taxes does significantly reduce the consumption of tobacco. Importantly, the impact of higher taxes is likely to be greatest on young people, who are more responsive to price rises than older people. Equally important, the discussion concludes that higher taxes will reduce the demand for tobacco most sharply in low- and middle- income countries where smokers are more responsive to price increases than in the high-income countries. Even with this reduced demand, however, governments' revenues need not be harmed. Indeed, as we shall show in chapter 8, higher taxes may bring substantially higher revenues in the short to medium term. Here, we briefly summarize the types of tobacco tax used by most govern- ments and assess how price increases affect demand. The evidence from low- and middle-income countries is compared with that from high-income coun- tries. The implications for policy are discussed. Types of tobacco tax Tobacco taxes can take several forms. Specific tobacco taxes, added as a fixed amount to the price of cigarettes, allow the greatest flexibility and allow gov- ernments to raise the tax with less risk that the industry will respond with actions that keep low the real amount charged. Ad valoremn taxes, such as value- added taxes or sales taxes, are a percentage of the base price and are imposed by virtually all countries-often on top of the specific excise tax. Ad valorem taxes may be imposed at the point of sale or, as in many African countries, on the wholesale price. Taxes may vary according to the place of manufacture or the type of product; for example, some governments impose higher taxes on cigarettes produced abroad than on domestically produced ones, or on high-tar cigarettes compared with low-tar. An increasing number of countries now ear- mark taxes raised on tobacco for antismoking activities or other specific ac- tivities. For example, one of China's largest cities, Chongqing, and several U.S. states earmark part of the revenue from tobacco taxes for education about tobacco's effects, counter-advertising, and other control activities. Other coun- tries use earmarked tobacco taxes to support health services. The amount of tax charged varies from country to country (Figure 4.1). In the high-income countries, taxes amount to two-thirds or more of the retail price of a pack of cigarettes. In contrast, in the lower-income countries, taxes amount to not more than half the retail price of a pack of cigarettes. The effect of raising taxes on cigarette consumption A basic law of economics states that as the price of a commodity rises, the quan- tity demanded of that product will fall. In the past, researchers have argued that MEASURES TO REDUCE THE DEMAND FOR TOBACCO 39 FIGURE 41 AVERAGE CIGARETTE PRICE, TAX, AND PERCENTAGE OF TAX SHARE PER PACK, BY WORLD BANK INCOME GROUPS, 1996 3.50- Average price in US 80 Average tax in US$ Z3~ 3.00 -Tax as a percentage of price 70 , 2.50- * \~ 60 CD .2.503 10 0 a.) 0.00 0 High Upper Lower Low income middle income middle income income Countries by income Source: Authors' calculations tobacco's addictive mature would make it an exception to this rule: smokers, according to this argument, are sufficiently addicted to smoking that they will pay any price and continue to smoke the same number of cigarettes to satisfy their needs. However, a growing volume of research now shows that this argu- ment is wrong and that smokers' demand for tobacco, while inelastic, is never- theless strongly affected by its price. For example, tax increases in Canada between 1 982 and 1 992 led to a steep increase in the real price of cigarettes, and consumption fell substantially (Figure 4.2a). Similar decreases in cigarette con- sumption as the result of tax increases have been seen in the United Kingdom and a number of other countries. Conversely, lower taxes increased cigarette consumption in South Africa between 1979 and 1989 (Figure 4.2b). Research- ers have consistently found that price increases encourage some people to stop smoking, that they prevent others from starting in the first place, and that they reduce the number of ex-smokers who resume the habit.

MEASURES TO REDUCE THE DEMAND FOR TOBACCO 41 price increases make varying assumptions about whether smokers look ahead at the consequences of their actions or not. However, all models agree that, for an addictive substance such as nicotine, an individual's current consumption levels will be determined by his or her past consumption levels as well as by the current price of the good. This relationship between past consumption and current consumption has important implications for modeling the impact of price rises on demand for tobacco. If smokers are addicted, they will respond relatively slowly to price increases, but their response will be greater in the long term. The economics literature suggests that a real and permanent price increase will have approximately twice as great an impact on demand in the long run as in the short run. Diffiering responses to price increases in low-inicome and high- income countries When the price of a good rises, people on low incomes are in general more likely to cut back their consumption of that good than people on high in- comes; and, conversely, when the price falls, they are more likely to increase their consumption. The extent to which consumers' demand for a good changes in response to a price change is known as the price elasticity of demand. For example, if a price rise of 10 percent causes the quantity demanded to fall by 5 percent, the elasticity of demand is -0.5. The more price-responsive con- sumers are, the greater is the elasticity of demand. Estimates of elasticity vary from study to study. but there is reasonable evidence that in middle-income and low-income countries, elasticity of de- mand is greater than in high-income countries. In the United States, for ex- ample, researchers have found that a price rise of 10 percent for a pack of cigarettes decreases demand by about 4 percent (an elasticity of -0.4). Studies in China have concluded that a price rise of 10 percent reduces demand by more than in high-income countries; depending on the study, the elasticity estimates range between about -0.6 and -1.0. Studies in Brazil and South Af- rica have produced results in the same range. For low- and middle-income countries as a whole, then, a reasonable estimate of the average elasticity of demand would be -0.8, based on current data. There are further reasons why people in low-income countries are more likely to respond to cigarette price rises than people in high-income countries. The age structure of most low-income countries' populations is generally younger and research from the high-income countries suggests that, on the whole, young people are more price-responsive than older people. This is partly because they have lower disposable incomes, partly because some may, as yet, be less heavily addicted to nicotine, partly because of their more present-ori- ented behavior, and partly because they are more susceptible to peer influ- ences. Thus, if one young person stops smoking because he or she can no 42 CURBING THE EPIDEMIC longer afford to do it, friends are more likely to follow suit than amongst older age groups. A study by the U.S. Centers for Disease Control and Prevention found that demand elasticity among young adults aged between 18 and 24 in the United States was -0.6, higher than for smokers overall. Researchers con- clude that when prices are high, not only are existing young smokers more likely to quit, but that fewer potential young smokers will take up the habit. Based on the evidence currently available, we can therefore draw two clear conclusions. First, that tax increases are a highly effective way to reduce tobacco consumption in low- and middle-income countries, where most smokers now live; and, second, that the effect of such tax increases will be more marked in these countries than in high-income countries. The potential impact of tax increases on global denmandfor tobacco For the purposes of this report, researchers have modeled the potential impact of a range of tax increases on demand for cigarettes worldwide. The design of the model and its inputs are described in Box 4.1. The assumptions on which the model is based, concerning price elasticity, health impact, and other vari- ables, are highly conservative. Thus the results are likely to be underestimates of the potential. The model reveals that even modest price increases could have a striking impact on the prevalence of smoking and on the number of tobacco-related premature deaths among those alive in 1995. The researchers calculate that if there were a sustained real rise in the price of cigarettes of 10 percent over the average estimated price in each region, 40 million people worldwide would quit smoking, and many more who would otherwise have taken up smoking would be deterred from doing so. Given that not all quitters would avoid death. the number of premature deaths avoided is still extraordi- nary by any standards-10 million, or 3 percent of all tobacco-related deaths- from this price increase alone. Nine million of the premature deaths avoided would be in developing countries, of which 4 million would be in East Asia and the Pacific (Table 4.1). Difficulties in computing an optimal tax levelfor cigarettes There have been various attempts to decide what the "right" level of tax on cigarettes should be. To decide that level, the policymaker needs to have cer- tain empirical facts, some of which may not yet be available, such as the scale of the costs to nonsmokers. The level also depends on incomes and assump- tions on the basis of values that differ from one society to another. For ex- ample, some societies would place greater importance on the need to protect children than others.

The short-run ones, so that the results are likely to price elasticity for high-income coun- err on the low rather than the high tries was calculated to be relatively side. In economic terms the optimal tax would be one that equates the mar- ginal social cost of the last cigarette consumed with its marginal social ben- efits. However, as we saw in the previous chapter, the magnitude of those social costs and benefits is unknown, nearly impossible to measure, and the subject of considerable ongoing controversy. Few doubt that smokers impose physical costs on nonsmokers who are obliged to inhale their smoke, with the MEASURES TO REDUCE THE DEMAND FOR TOBACCO 45 biggest burden of passive smoking borne by the children and spouses of smok- ers. Yet, since some economists consider the family to be the basic decisionmaking unit in society, they regard spouses' and children's exposure to tobacco smoke as an internal cost that is taken into account in the family's decisions about smoking, rather than an external cost imposed by smokers on others. Meanwhile, the scale of other costs, such as those from publicly fi- nanced healthcare for treating smoking-related diseases, is difficult to judge, as we have seen. Studies from the United States that attempt to compute the economically optimal tax produce a wide range of estimates, from a few cents to several dollars. Another approach to setting tax levels is to select a rate that would achieve a specific reduction in cigarette consumption and hence meet a specific public health target, rather than one that will cover the social costs of smoking. Yet another objective would be to set tax levels to maximize the revenues gener- ated from these relatively efficient taxes. Rather than attempt to suggest an optimal tax level, this report proposes a more pragmatic approach: to observe the tax levels adopted by countries with comprehensive and effective tobacco control policies. In such countries, the tax component of the price of a pack of cigarettes is between two-thirds and four-fifths of the total retail cost. These levels can be used as a yardstick for proportionate increases in prices elsewhere.2 Nonprice measures to reduce demand: consumer information, bans on advertising and promotion, and smoking restrictions There is extensive evidence from the high-income countries that the provi- sion of information to adult consumers about the addictive nature of tobacco and its burden of fatal and disabling diseases can help to reduce their con- sumption of cigarettes. In this section, we review what is known about the effectiveness of a range of types of such information, including publicized research into the health consequences of smoking; warnings on cigarette packs and on advertisements; and counter-advertising. We shall also summarize what is known about the effects of the tobacco advertising and promotion activi- ties, and what happens when these activities are banned. Because the differ- ent types of information are often available to consumers concurrently, it is difficult to disaggregate their individual effects, but the growing body of re- search and experience in high-income countries suggests that each can have a significant impact. Importantly, the impact appears to vary across different social groups. In general, young people appear to be less responsive to infor- mation about the health effects of tobacco than older adults, and more edu- cated people respond more quickly to new information than those with no or 46 CURBING THE EPIDEMIC minimal education. An awareness of these differences is useful for policymakers when planning a mix of interventions that is tailored to the par- ticular needs of their own country. Publicizedfindings of research on the health effects of smoking The long-term downward trend in smoking prevalence in most high-income countries over the past three decades has coincided with a long-term upward trend in people's levels of knowledge about the harmful effects of smoking. In 1950, in the United States, only 45 percent of adults identified smoking as a cause of lung cancer. By 1990, 95 percent did so. Over approximately the same period, the proportion of the U.S. population that smoked fell from more than 40 percent to about 25 percent. On many occasions in the high-income countries, the public has been exposed to "information shocks" about the health effects of smoking, such as the publication of official reports on the subject that receive wide media cover- age. The impact of these has been studied in such diverse countries as Finland, Greece, Switzerland, Turkey, the United Kingdom, the United States, and South Africa. In general, the impact is greatest, and most sustained, at a relatively early stage in a population's epidemic of tobacco-related disease, when gen- eral awareness of the health risks of smoking are low. As knowledge increases, new information shocks become less effective. An analysis in the United States, based on times-series data between the 1930s and the late 1970s, suggests that three information shocks, including an influential report of the Surgeon General in 1964, together reduced consump- tion by as much as 30 percent over the period. In more recent decades, studies from several high-income countries have concluded that publicized informa- tion about the health effects of tobacco has been responsible for a sustained decline in consumption. For example, between 1960 and 1994 in the United States, parents decreased their consumption of cigarettes much more rapidly than single adults living without children. Researchers have concluded that parents' increasing awareness of the hazards of passive smoking for their chil- dren has deterred them from smoking. In low-income and middle-income countries to date, there has been little research to monitor the impact of information shocks. However, smoking trends in China are being monitored following the recent publication of major studies of the health effects of smoking there. Clearly, a prerequisite for publicizing data that portray the health consequences of smoking is to collect those data in the first place. Recent moves in South Africa and India to "count the tobacco dead" through the inexpensive method of noting individuals' smoking status on their death certificates should help to provide data that are needed to de- scribe the shape and size of the tobacco epidemic in each region. MEASURES TO REDUCE THE DEMAND FOR TOBACCO 47 Warninig labels Even in countries where consumers have had reasonable access to informa- tion about the health effects of smoking, the evidence suggests that there are widespread misperceptions about these effects, due, in part, to cigarette pack- aging and labeling. For example, in the past two decades, many manufactur- ers have labeled certain classes of cigarette as "low tar" and "low nicotine." Many smokers in high-income countries believe that these brands are safer than other cigarettes, although the research literature concludes that no ciga- rettes are safe. Studies suggest that many consumers are confused about the constituents of tobacco smoke, and that packaging fails to give them adequate information about the products they are buying. Since the early 1960s a growing number of governments have required cigarette manufacturers to print health warnings on their products. By 1991, 77 countries required such warnings, although very few of these countries insisted on strong warnings with rotating messages, such as the one illustrated in Figure 4.3. A study from Turkey suggests that health warnings caused consumption there to fall by about 8 percent over six years. In South Africa, when serious warning labels were introduced in 1994, there was a significant fall in con- sumption. More than half (58 percent) of smokers questioned for that study said they were motivated by the warning labels to quit or reduce their smok- ing. However, one key weakness of warning labels is that they will not reach some poorer individuals, particularly children and adolescents, in low-income countries. Among such consumers, it is common to buy cigarettes singly rather than in packs. It has sometimes been argued that, in the more informed populations where smoking has been widespread for many decades, smoking preva- lence is unlikely to fall much lower than it has already as a result of ciga- rette pack warning labels. However. evidence from Australia, Canada, and Poland suggests that such labels can still be effective, provided that they are large, prominent, and contain hard-hitting and specific factual infor- mation. In Poland in the late 1990s, new warning labels that occupy 30 percent of each of the two largest sides on the cigarette pack have been found to be strongly linked with smokers' decisions to quit or cut down their smoking. Among Polish male smokers, 3 percent said they had quit following the introduction of the labels: an additional 16 percent said they had tried quitting, and a further 14 percent said they understood the health effects of smoking better because of the warnings. Among women, the ef- fects were similar. In Australia, warning labels were strengthened in 1995. The impact appears to have been greater in inducing smokers to quit than when the older, less strongly worded labels were used. In Canada, a survey 48 CURBING THE EPIDEMIC FIGURE 4.3 A STRONG WARNING LABEL Proposed prototype of plain packaging for cigarettes in Australia HEALTH AUTHORITIES WARN ABOUT SMOKING CAUSES LUNG CANCER Tobacco smoke contains many cancer causing chemicals.

Washington, D.C. in 1996 suggested that half of smokers intending to quit or cut back their consumption were motivated by what they had read on their cigarette packs. Mass media counter-advertising There have been a number of studies to analyze the impact of negative messages about smoking on cigarette consumption. These negative mes- sages, or counter-advertising, are disseminated by governments and health- promotion agencies, and they have been consistently found to reduce overall consumption, according to studies at both national and local levels from North America, Australia, Europe, and Israel. Swiss researchers concluded from a study of adult tobacco consumption conducted between 1954 and 1981 that antismoking publicity in the mass media permanently reduced consumption by 11 percent over the period. In Finland and Turkey, anti- smoking campaigns are also judged to have contributed to declines in con- sumption. MEASURES TO REDUCE THE DEMAND FOR TOBACCO 49 School antismoking educational programs School antismoking programs are widespread, particularly in the high-income countries. However, they appear to be less effective than many other types of information dissemination. Even programs that have initially reduced the up- take of smoking appear to have only a temporary effect; they can somewhat delay the initiation of smoking but not prevent it. The apparent weakness of school-based programs may have less to do with their nature than with the audience at which they are targeted. As we have seen, adolescent responses to information about the long-term consequences of an action on their health are not the same as adult responses, partly because of more present-oriented be- havior and partly because adolescents tend to rebel against adults' advice. Cigarette advertising and promotion Policymakers who are interested in controlling tobacco need to know whether cigarette advertising and promotion affect consumption. The answer is that they almost certainly do, although the data are not straightforward. The key conclusion is that bans on advertising and promotion prove effective, but only if they are comprehensive, covering all media and all uses of brand names and logos. We discuss the evidence briefly here. There is a vigorous debate about the impact of cigarette advertising on consumers. On the one hand, public health advocates argue that such advertis- ing does increase consumption. In contrast, the tobacco industry has argued that its advertising does not recruit new smokers but merely encourages con- firmed smokers to stay with, or switch to, a particular brand. On the face of it, empirical studies of the relationship between advertising and sales have tended to conclude either that advertising has no positive effect on consumption, or that it shows only a very modest positive effect. However, these studies may be misleading, for the following reasons. First, economic theory suggests that ad- vertising will have a diminishing marginal impact on demand; that is, when advertising for a product increases, consumers will gradually respond less and less to additional advertising, and, ultimately, increased advertising will stop making any impact on them at all. Advertising in the tobacco industry is at a relatively high level, around 6 percent of sales revenues, about 50 percent higher than the average industry. Thus, any increased consumption that may result from increased advertising is likely to be very small and difficult to detect. This does not mean that, in the absence of advertising, consumption would necessar- ily be as high as it is in the presence of advertising-only that the marginal impact of an increase in advertising is negligible. Second, data that recold the impact of advertising on sales are usually highly aggregated for relatively long time periods, for all advertisers, in all media, and often over large populations. 50 CURBING THE EPIDEMIC Any subtle changes that might be apparent at a more disaggregated level of analysis are therefore obscured. In studies that use less aggregated data, re- searchers find more evidence of a positive effect of advertising on consump- tion. but such studies are expensive and time-consuming and, therefore, rare. Given the problems with these approaches, researchers have tumed instead to studying what happens when tobacco advertising and promotion are banned as an indirect means of gauging their effect on consumption. The inmpact of advertising bans When govemments ban tobacco advertising in one medium, such as televi- sion, the industry can substitute advertising in other media with little or no effect on overall marketing expenditures. Accordingly, studies that have ex- amined the effect of partial cigarette advertising bans have found little or no effect on smoking. However, where there are multiple restrictions on advertis- ing in all media and on promotional activities, there are relatively few alterna- tive outlets for the industry. Since 1972, most high-income countries have introduced stronger restrictions across more media and on various forms of sponsorship. A recent study of 22 high-income countries based on data from 1970 to 1992 concluded that comprehensive bans on cigarette advertising and promotion can reduce smoking, but more limited partial bans have little or no effect. If the most comprehensive restrictions were in place, the study con- cluded, tobacco consumption would fall by more than 6 percent in high-in- come countries. Modeling based on these estimates suggests that the European Union's ban on advertising (see Box 4.2) could reduce cigarette consumption within the European Union by nearly 7 percent. Another study of 100 coun- tries compared consumption trends over time in those with relatively complete bans on advertising and promotion and those with no such bans. In the coun- tries with nearly complete bans, the downward trend in consumption was much steeper (Figure 4.4). It is important to note that, in this study, other factors may also have contributed to the decline in consumption in some countries. Beyond the economic literature, meanwhile, there are other types of re- search, such as surveys of children's recall of advertising messages, that con- clude that advertising and promotion do indeed affect demand for cigarettes and attract new recruits. Children's attention is attracted by such advertising, and they remember its messages. There is also growing evidence that the in- dustry is directing increasing shares of its advertising and promotion activity toward markets where there is judged to be growth or potential for growth, including some youth markets and specific minority groups among whom smoking has until recently been uncommon. This noneconomic body of re- search may be of particular interest to policymakers concerned about smoking trends within specific groups in the population.

The change is due to a higher rate of decrease in consumption for the ban group than the nonban group. Source: Saffer, Henry. The Control of Tobacco Advertising and Promotion. Background paper. Restrictions on smoking in public and worlkplaces A growing number of coultries and states are now implementing restrictions on smoking in public places such as restaurants and transport facilities. In some countries, such as the United States, some workplaces are also covered by public restrictions. The most obvious benefit of these restrictions is clearly to nonsmokers, who are spared exposure to the health risks and nuisance of environmental tobacco smoke. But, as we have seen, most nonsmokers' expo- sure to others' smoke is not in public places or workplaces, but in the home. These restrictions therefore represent only a partial means of addressing the needs of nonsmokers. A second effect of smoking restrictions is that they reduce some smokers' consumption of cigarettes and induce some to quit.

MEASURES TO REDUCE THE DEMAND FOR TOBACCO 53 restrictions have reduced tobacco consumption by between 4 and 10 percent, according to various estimates. For such restrictions to work, it appears that there must be a general level of social support for them, and an awareness of the health consequences of exposure to environmental tobacco smoke. Out- side the United States, there are comparatively few data on the effectiveness of indoor smoking restrictions. The potential impact of nonprice measures on global demand for tobacco We have described the evidence for the effectiveness of a number of nonprice measures, including information for consumers, dissemination of scientific reports and research, warning labels, counter-advertising, comprehensive bans on advertising and promotion, and smoking restrictions. As part of the back- ground work for this report, the model described in Box 4.1 was used to assess the potential impact of a comprehensive package of these nonprice measures on cigarette consumption worldwide. Because until now there have been few attempts to estimate the aggregate impact of these measures, the model was constructed on conservative assumptions. It assumes, on the basis of the exist- ing measures of effectiveness for individual nonprice measures, that their com- bined impact would be to persuade between 2 and 10 percent of consumers to quit. To be conservative, the model assumes that the measures would have no impact on the numbers of cigarettes smoked daily by those who do not stop. Based on these assumptions, a package of nonprice measures could re- duce the number of smokers alive in 1995 by 23 million worldwide, even at the lower end of the estimate-that is, if packages implemented worldwide re- duced the number of consumers by only 2 percent (see Table 4.2). Using the previous assumptions about the number of quitters who would avoid death, the model suggests that 5 million lives could be saved. Nicotine replacement therapy and other cessation interventions In addition to higher taxes and nonprice measures, there is a third set of mea- sures to help reduce tobacco consumption. These are cessation treatments and programs of various types, including individual training, hospital treatment, counseling programs, and the growing range of pharmacological products de- signed to aid cessation, such as nicotine replacement therapy (NRT) products and an antidepressant drug with the generic name bupropion. NRT products, in the form of patches, gums, sprays, and inhalators deliver low doses of nico- tine without delivering the other harmful constituents of tobacco smoke. Used properly, NRT is regarded as safe and effective by major medical organiza- tions in the high-income countries. A large body of research concludes that it 54 CURBING THE EPIDEMIC TABLE 4.2: POTENTIAL NUMBER OF SMOKERS PERSUADED TO QUIT, AND LIVES SAVED, BY A PACKAGE OF NONPRICE MEASURES (Millions) For smokers alive in 1995 Change in number of smokers Change in number of deaths if package reduces if package reduces the prevalence of smoking by: the prevalence of smoking by: Region 2 percent 10 percent 2 percent 10 percent East Asia and Pacific -8 -40 -2 -10 Eastern Europe and Central Asia -3 -15 -0.7 -3 Latin America and Caribbean -2 -10 -0.5 -2 Middle East and North Africa -0.8 -4 -0.2 -I South Asia (cigarettes) -2 -9 -0.3 -2 South Asia (bidis) -2 -10 -0.4 -2 Sub-Saharan Africa -1 -7 -0.4 -2 Low/Middle Income -19 093 -4 L-22 High Income -4 -21 -1 -5 World -23 -114 -5 -27 Note: Numbers have been rounded.

Bupropion has also been shown to be effective in trials in the United States. A key advantage of NRT is that it can be self-administered. This enhances its practical potential to smokers who wish to quit in countries where there are limited resources for intensive support by health professionals. NRT is prescribed solely for treating the symptoms of nicotine withdrawal in smokers who are trying to quit. NRT products have not, to date, been linked with any cardiovascular or respiratory disease, and there is consensus that they are a much safer source of nicotine than tobacco. Nicotine does, of course, produce physiological effects, including raising blood pressure. However, com- pared with cigarettes, the doses of nicotine delivered by NRT products are smaller, and they are delivered more slowly. NRT represents a means of reduc- ing the costs of quitting in regular smokers. The availability of NRT varies from country to country. In some high- income countries, products are sold over the counter, while in others they are available only through prescription. Models based on data from the United States suggest that, if NRT were made available over the counter, significantly MEASURES TO REDUCE THE DEMAND FOR TOBACCO 55 TABLE 4.3 EFFECTIVENESS OF VARIOUS CESSATION APPROACHES Increase in percentage of smokers Intervention and comparison abstainingfor 6 months or more Brief advice to stop (3 to 10 minutes) by clinician versus no advice 2 to 3 Adding NRT to brief advice versus brief advice alone or brief advice plus placebo 6 Intensive support (for example, smokers' clinic) plus NRT versus intensive support or intensive support plus placebo 8 Source: Raw, Martin, and others. 1999. Data are from the Agency for Health Care Policy and Research. and the Cochrane Library. more people would quit and more lives would be saved than if NRT were available only through prescription. Over five years, the model predicts, al- most 3,000 lives would be saved in the United States alone. There is also evi- dence that smokers want this type of help: in the United States. sales of NRT products increased by 150 percent between 1996, when products were first sold over the counter, and 1998. Outside the high-income countries, the availability of NRT in any form is patchy; for example, NRT products are sold in Argentina, Brazil, Indonesia, Malaysia, Mexico, the Philippines, South Africa, and Thailand, but in some of these countries supplies are restricted to a few major urban areas. In some middle-income countries and many low-income countries, NRT products are not available at all. A day's supply of NRT products costs about the same as the average daily dose of tobacco, but because they are usually sold as a whole course, they require a comparatively large single payment. Compared with cigarettes, the sale of NRT products is highly regulated. Given the evidence, many policymakers might consider widening access to NRT as a valuable component of tobacco control policies. One option would be to reduce the regulation on sales of these products, for example, by increas- ing the range of outlets and the hours of sale of such products, and reducing restrictions on packaging. Another option, given the evidence that NRT would help to reduce the costs of quitting, would be to consider making NRT available at subsidized prices, or free, for limited periods to smokers on low incomes who wish to quit. This approach is already being tested in some settings. In the United Kingdom, for example, there are proposals for the poorest smokers to be made eligible for limited free supply of NRT if they decide to quit. Targeting such services to the poor is a challenge in all countries. 56 CURBING THE EPIDEMIC Clearly, any decision to widen access to NRT must be considered care- fully. Most societies would wish to avoid promoting the sale of any addictive good to children. However, the consensus of health professionals in high- income countries is that NRT, used effectively, is beneficial and should be encouraged for adult smokers who want to quit. The cost-effectiveness of nicotine replacement therapy has not been studied widely, especially in the low-income and middle-income countries where most smokers live. It is clear that more information on cost-effectiveness would be useful for policymakers at local levels, both in determining whether these devices should have a claim on limited public funds, and in giving policymakers a firmer basis on which to act. As background work to this report, the potential impact of more widely available NRT was modeled using the same methods as above. To be conser- vative, it was assumed that the effectiveness of the therapy might be lower than the available studies from high-income countries suggest. With the con- servative assumption that quit rates among users of NRTs would be double that of nonusers, but that only about 6 percent of smokers would use NRTs to quit, we estimate that the 6 million smokers alive in 1995 could be enabled to quit, and 1 million deaths could be averted. If, on the other hand, 25 percent of smokers used NRT, we find that 29 million smokers alive in 1995 would be enabled to quit, and 7 million deaths could be averted. Notes 1. Smith, Adam.

For example, if tax is to account for four-fifths of the retail price, this requires prices to be increased by four times the manufacturer's (untaxed) price per pack. Thus, for instance, if a nontax price is equal to $0.50, then the tax rate would be 0.5 x 4 = $2. Retail price would be equal to $2 (tax) + $0.50 (manufacturing price) = $2.50. The impact on retail price would, of course, vary between countries, depending on retail factors such as the wholesale price, but broadly, an increase of this order would raise the population-weighted price by between 80 and 100 percent in low- and middle- income countries. CHAPTER 5 Measures to Reduce the Supply of Tobacco WYHEREAS there is abundant evidence that the demand for tobacco can be reduced, there is much less evidence of success in reducing its supply. Here, we briefly discuss the experience of countries in attempting to restrict access to tobacco and to reduce its supply through trade restrictions or agricul- tural policies. In the second section of the chapter, we discuss one key way in which governments can reduce tobacco supplies, by controlling smuggling. The limited effectiveness of most supply-side interventions A basic observation in markets is that, if one supplier of a commodity is pre- vented from operating, another will quickly emerge to take its place as long as there is a strong incentive to do so. There are currently clear incentives to supply tobacco, as the discussion here sets out. Prohibition of tobacco Given tobacco's unprecedented capacity to damage health, a few public health advocates have called for it to be prohibited, arguing that the problem of to- bacco is not in its consumption, but its production. Advocates of tobacco pro- hibition point to the marked reduction in alcohol-related diseases when alcohol supply was restricted earlier in the 20th century. For example, when alcohol supplies were restricted in Paris, France, during World War II, alcohol con- sumption fell by 80 percent per capita. Deaths from liver disease in men were 57 58 CURBING THE EPIDEMIC halved within one year and fell by four-fifths after five years. After the war ended and alcohol became freely available, mortality from liver disease re- turned to prewar levels. However, for a number of reasons the prohibition of tobacco is unlikely to be either feasible or effective. First, even when substances are prohibited, they continue to be widely used, as is the case with many illicit drugs. Second, prohibition creates its own sets of problems: it is likely to increase criminal activity and entail costly police enforcement. Third, from an economic per- spective, optimal tobacco consumption is not zero. Fourth, the prohibition of tobacco is unlikely to be politically acceptable in most countries. In India, recent attempts to ban a chewed type of tobacco known as gutka failed, largely due to a political backlash against prohibition. Restrictions on youth access to tobacco There have been a number of attempts to impose restrictions on the sale of cigarettes to teenagers in high-income countries. In their existing form, such restrictions have not been shown to be successful. In general, youth restric- tions are difficult to enforce, especially given that young teenagers often ob- tain cigarettes from their older peers, and, sometimes, from their parents. Moreover, in low-income countries where tobacco consumption is rising, the necessary systems, infrastructure, and resources for implementing such re- strictions and enforcing them are much less widely available than in the high- income countries. Crop substitution and diversification More than 100 countries grow tobacco, of which about 80 are developing coun- tries. Four countries account for two-thirds of the total production: in 1997, China was responsible for 42 percent of all tobacco grown, with the United States, India, and Brazil producing about 24 percent between them. The top 20 countries produce more than 90 percent of the total (see Table 5.1). Over the past two decades, the share of global production by high-income countries has fallen from 30 to 15 percent, while that by countries in the Middle East and Asia has risen from 40 to 60 percent. Africa's share rose from 4 to 6 percent, and other regions have changed little. Whereas China uses most of its tobacco crop for its domestic market, other major producers export large proportions of theirs. Brazil, Turkey, Zimbabwe, Malawi, Greece, and Italy all export more than seven-tenths of their crop. Only two countries worldwide are significantly dependent on raw tobacco for their export earnings-Zimbabwe, with 23 percent of export earnings, and Malawi, with 61 percent.

Tobacco is a major earner for a few countries with heavily agrarian economies, including Malawi, Zimbabwe, India, and Turkey. Historically, tobacco is a highly attractive crop to farmers, providing a higher net income yield per unit of land than most cash crops and substan- tially more than food crops. In the best tobacco-growing areas of Zimbabwe, for example, tobacco is approximately 6.5 times more profitable than the next- best alternative crop. Farmers also find tobacco an attractive crop for more practical reasons. First, the global price of tobacco is relatively stable com- pared with other crops. The stability allows farmers to plan ahead and obtain credit for other enterprises as well as tobacco farming. Second, the tobacco industry generally supplies farmers with strong in-kind support, including materials and advice. Third, the industry often gives farmers loans. Fourth, other crops may cause farmers problems with storage, collection, and deliv- ery. Tobacco is less perishable than many crops, and the industry may assist with its delivery or collection; by contrast, late collection, late payment, and price fluctuations may blight other crops. There have been a number of experimental schemes to substitute other crops for tobacco. However, with the arguable exception of Canada, there is no hard evidence that these schemes succeed as a means of reducing tobacco consump- tion, because of the lack of motivation for farmers to participate while current tobacco prices persist and because of the readiness of other suppliers to replace them. Crop substitution will, however, occasionally have a place in broader diversification programs, if it aids the poorest tobacco farmers in their transition to other livelihoods. We discuss this issue in more detail in the next chapter. Price supports and subsidies on tobacco production While developing countries tend to tax export earnings from tobacco, high- income countries such as the United States and member states of the European Union, together with China, traditionally provide price supports and other sub- sidies to farmers who grow it. The motives for subsidizing tobacco production include keeping prices high and stable, supporting small family farms, con- trolling imports of tobacco from abroad to conserve foreign exchange, and maintaining political support. Often these subsidies go hand in hand with im- port restrictions. With these price-support policies for producers, high-income countries' governments artificially raise world prices of tobacco and tobacco products. Economists have argued that, whenever the price is raised in this way, smokers may respond by reducing their consumption. However, the evidence shows that if there is such an effect on consumption, it is very small. In most high- 62 CURBING THE EPIDEMIC income countries such as the United States, the producer price of tobacco leaf accounts for only a small part of the price of cigarettes. In addition, imports of lower-priced tobacco are rising. Thus, such price supports and subsidies will make only a negligible difference to the price of a pack. A recent analysis indicates that these programs raise prices by 1 percent in the United States. An increase of this order will have almost no impact on consumption. Accord- ingly, the removal of subsidies is unlikely to cause significant increases in cigarette consumption. It is not clear how the removal of price supports and subsidies would af- fect global production. Higher domestic prices in the United States may help to raise the global price of raw tobacco leaf, offering better returns to farmers in low-income countries. On the other hand, there would be mixed effects for farmers in low-income countries if both subsidies and trade restrictions were removed. If, for example, the price of domestically produced tobacco in the United States were to fall because of the removal of subsidies, cigarette manu- facturers there might use more of it, in turn reducing their imports of lower quality imports from low-income countries. But at the same time, with freer trade, imports of such tobacco could increase. Regardless of their minimal impact on consumption, such price supports and subsidies make little sense in a framework of sound agricultural and trade policies. Their most significant function is perhaps political, enlarging the number of people with a vested interest in tobacco production. Restrictions on international trade Free trade has been shown to increase consumers' options and make produc- tion more efficient. A number of studies have shown that it brings increased growth to low-and middle-income countries. While the arguments in favor of free trade in general, then, are robust, tobacco is clearly more harmful to health than most other traded consumer goods. The key issue for policymakers is to decide how to control tobacco without jeopardizing the otherwise beneficial consequences of free trade. As we saw in chapter 1, trade liberalization has contributed to an increase in the consumption of tobacco in low- and middle- income countries. It might appear logical that, in turn, trade restrictions would stem that increase. However, there are a number of reasons why such restric- tions would have undesirable consequences. One key reason is that restric- tions would be likely to prompt retaliatory action that could reduce economic growth and incomes. Trade liberalization, meanwhile, has resulted in an inter- national response through the General Agreement on Tariffs and Trade (GATT) that gives countries the right to adopt and enforce measures to protect public health. The condition for such measures is that they should be applied equally to domestic and imported products. Article XX of GATT explicitly states that MEASURES TO REDUCE THE SUPPLY OF TOBACCO 63 measures that are needed to protect human health shall not be prevented by the requirement for free trade. In 1990, Thailand attempted to ban cigarette imports and advertising, a move that prompted a challenge from U.S. tobacco companies. A GATT panel investigated the situation and ruled that Thailand could not ban imports of cigarettes, but that it could impose taxes, advertising bans, and price restric- tions, and that it could demand that all manufacturers whose products were available in Thailand should label their products with strong warning labels and descriptions of the ingredients. The GATT panel's ruling has even been interpreted as saying that Thailand could ban sales of all tobacco products in the country, provided the ban were applied symmetrically to domestically pro- duced and foreign-produced cigarettes. Thailand implemented strong demand- reduction measures, including comprehensive bans on advertising and promotion, and strong waming labels on cigarette packs. This landmark deci- sion, and Thailand's prompt and firm response, have set a precedent for coun- tries to intervene to reduce tobacco demand on public health grounds while maintaining the principles of free trade. Firm action on smuggling Cigarette smuggling is a serious problem. Researchers estimate that some 30 percent of internationally exported cigarettes, or about 355 billion cigarettes, are lost to smuggling. This is a far higher percentage than most consumer goods that are internationally traded. The problem is acute where there are large variations in tax between neighboring states or countries, where there is widespread corruption. and where contraband sales are tolerated. Here, we briefly describe the extent of the smuggling problem and discuss the options for its control. The benefit of controlling smuggling is not principally that it reduces supply, but that it helps the effective implementation of price increases that reduce demand. Differences in price between countries or states will clearly increase the incentives to smuggle cigarettes. However, the determinants of smuggling ap- pear to be more than price alone. A study prepared for this report assessed the extent to which other factors, such as general levels of corruption in a country, contribute to the size of the smuggling problem. Using standard indicators of corruption levels based on Transparency International's Index of Countries, the study concluded that, with notable exceptions. the level of tobacco smuggling tends to rise in line with the degree of corruption in a country (Figure 5.1). Large-scale tobacco smuggling relies on criminal organizations, compara- tively sophisticated systems for distributing smuggled cigarettes in the destina- tion country, and a lack of control on the international movement of cigarettes. Most smuggled cigarettes are well-known intemational brands.

Cambridge, Mass.: National Bureau of Economic Research, forthcoming. of money are involved: organized smugglers can buy a container of 10 million cigarettes, on which they pay no taxes, for $200,000. The fiscal value of this quantity of cigarettes in the European Union is at least $1 million, taking ac- count of excise duties, value-added tax (VAT), and import taxes. The profits to smugglers are thus so high that they can absorb long-distance travel costs. Cigarettes are usually smuggled in transit between their country of origin and their official destination. To encourage trade between countries, a so-called transit system operates that temporarily suspends custom duties, excise, and VAT payable on goods originating in country A and bound for country B while they are in transit through countries C, D, and so on. However, many cigarettes simply fail to arrive at their destination, having been bought and sold by unof- ficiat traders. Another form of smuggling is so-called "round-tripping" where there are relatively large price differentials between neighboring countries. Exported cigarettes from Canada, Brazil, and South Africa, for example, have been documented entering neighboring countries and then reappearing in their country of origin at cut-rate prices, untaxed. MEASURES TO REDUCE THE SUPPLY OF TOBACCO 65 The success of smuggling relies on the cigarettes passing through a large number of owners in a short time, making it virtually impossible to track their movements. Additionally, poor enforcement of illegal sales and difficulty in separating legal and illegal sales may reduce the risks to smugglers. For ex- ample, in Russia, and in many low-income countries, the majority of ciga- rettes are sold on the streets. Economic theory suggests that the tobacco industry itself will benefit from the existence of smuggling. Studies of the impact of smuggling show that when smuggled cigarettes account for a high percentage of the total sold, the aver- age price for all cigarettes, taxed and untaxed, will fall, increasing sales of cigarettes overall. The presence of smuggled cigarettes in a market that has hitherto been closed to imported brands will help to increase the demand for those brands, and hence increase their market share. It will also influence gov- ernments toward keeping tax rates low. There is as yet very little experience and research on the effectiveness of different antismuggling measures. However, policymakers may consider sev- eral options. First, the legality or otherwise of cigarette packs could be made more immediately visible to consumers and law enforcers by, for example, the addition of prominent tax stamps-which must be difficult to forge-on duty- paid packs, and special packaging on duty-free packs. Strong and varied warning labels in local languages also help to distinguish legal from illegal sales. Sec- ond, the penalties for smuggling could be made sufficiently severe to deter those who currently perceive the risks of prosecution to be low. Third, all par- ties in the chain between manufacturer and consumer could be licensed. This is already the case in France and Singapore. Fourth, manufacturers could be required to stamp each pack of cigarettes with a serial number to enable track- ing. With increasingly sophisticated technology, pack marking could provide information about the distributor, wholesaler, and exporter, too. Fifth, manu- facturers could be required to take responsibility for better record-keeping to ensure the final destination of their products is as officially intended. Comput- erized control systems would enable governments to track individual consign- ments and inspect their progress at any time. Such a system is already in place in Hong Kong, China. Sixth, exporters could be required to label packs with the name of the country of final destination, and print health warnings in the language of that country. Where international companies produce their ciga- rettes locally, this could also be stated on the pack, to aid detection and in- crease awareness of smuggled cigarettes. A number of countries are stepping up their antismuggling activities. For example, the United Kingdom recently announced a package worth more than $55 million to combat the smuggling of tobacco and alcohol, including the provision of new dedicated staff posts. As experience grows, the prospects for better controls in all affected countries are likely to improve. CHAPTER 6 The Costs and Consequences of Tobacco Control DESPITE the obvious threat from tobacco to global health, many governments, particularly in low- and middle-income countries, have not taken significant action to reduce its toll. In some cases, this is because the scale of the threat is underestimated, or because of a mistaken belief that little can be done to reduce consumption. However, many governments have hesitated to act because of concerns that tobacco control will have undesirable economic consequences. In this chapter, we discuss some common concerns about the consequences of tobacco control for economies and for individuals, and then assess the cost-effectiveness of interventions. Will tobacco control harm the economy? We briefly discuss some of the common concerns in turn, in the form of an- swers to some of the most frequently asked questions. If demandfor tobacco falls, will there be massive job losses? A major reason for governments' inaction over tobacco is their fear of creating unemployment. This fear is derived mainly from the arguments of the tobacco industry, which says that control measures will result in millions of job losses across the world. Yet a closer inspection of the arguments, and the data on which they are based, suggests that the negative effects of tobacco control on 67 68 CURBING THE EPIDEMIC employment have been greatly overstated. Tobacco production is a small part of most economies. For all but a very few agrarian countries heavily depen- dent on tobacco farming, there would be no net loss of jobs, and there might even be job gains if global tobacco consumption fell. This is because money once spent on tobacco would be spent on other goods and services, thereby generating more jobs. Even the handful of tobacco-dependent economies will have a market big enough to ensure their jobs for many years to come, even in the face of gradually declining demand. The tobacco industry estimates that 33 million people are engaged in tobacco farming worldwide. This total includes seasonal workers, part-time workers, and family members of farmers. It also includes farmers who grow other products in addition to tobacco. Of the total, some 15 million are in China, and another 3.5 million in India. Zimbabwe has some 100,000 to- bacco farm workers. Relatively small but still significant numbers are em- ployed in the high-income countries: the United States, for example, has 120,000 tobacco farms, and the European Union has 135,000-mostly small-farms in Greece, Italy, Spain, and France. The manufacturing side of the tobacco industry is only a small source of jobs, as it is highly mecha- nized. In most countries tobacco manufacturing jobs account for well be- low 1 percent of total manufacturing employment. There are a few important exceptions to this pattern, with Indonesia relying on tobacco manufactur- ing for 8 percent of its total manufacturing output, and Turkey, Bangladesh, Egypt, the Philippines, and Thailand relying on it for between 2.5 and 5 percent of theirs. On the whole, though, it is clear that tobacco production is a small part of most economies. Statements that tobacco controls will mean massive job losses are usu- ally based on studies funded by the tobacco industry that estimate the num- ber of jobs attributable to tobacco in each sector, the incomes associated with these jobs. tax revenues generated by tobacco sales, and the contribu- tion of tobacco to the country's trade balance wherever this is relevant. These studies also estimate the multiplier effect of money earned in to- bacco farming and manufacturing in stimulating activity elsewhere in the economy. However, the methods used for these studies have been criti- cized. First, they assess the gross contribution of tobacco to employment and the economy. Rarely, if ever, do they take account of the fact that if people stop spending money on tobacco, they usually spend it on other things instead, thus generating alternative jobs to compensate. Second, their methods overstate the impact of any intervention that reduces demand be- cause their estimates of certain variables, such as trends in smoking and trends in the mechanization of cigarette production, tend to be static. Independent studies of the impact of tobacco on individual economies reach different conclusions. Rather than consider the gross economic con- THE COSTS AND CONSEQUENCES OF TOBACCO CONTROL 69 tribution of tobacco to the economy, the independent studies estimate its net contribution, that is, the benefit to the economy of all tobacco-related activity after taking into account the compensating effect of alternative jobs that would be generated by the money not spent on tobacco. The con- clusions of these studies are that tobacco control policies would have little or no negative effect on total employment, except in a very few tobacco- producing countries. A study in the United Kingdom found that jobs would increase by more than 100,000 full-time equivalents in 1990 if former smokers spent their money on luxury items, and if any decline in tax revenues brought about by nontax measures to reduce demand were offset by taxing other goods and services. A study in the United States found that the number of jobs would rise by 20,000 between 1993 and 2000 if all domestic con- sumption was eliminated. While there would be net job losses in the to- bacco-growing region of the United States, the national total would rise because of the money freed up from tobacco purchases and injected into other areas of the economy. Of course, industry transitions can be difficult and may create social and political problems in the short term. But econo- mies go through many such transitions, and this one would not be excep- tional. The findings are not restricted to the high-income countries. Indeed, there are some low-income countries that might experience striking ben- efits. For example, according to a background study for this report, Bangladesh, whose cigarettes are almost all imported, would benefit mark- edly if all domestic consumption were eliminated. Within the formal sec- tor of its economy, there could be a net gain in jobs of as much as 18 percent if smokers spent their money on other goods and services. The impact on economies of a global fall in tobacco consumption will vary, depending on the type of economy. Countries can be grouped into three categories. The first category comprises countries that produce more raw to- bacco than they consume, that is, net exporters. Examples include Brazil, Kenya, and Zimbabwe. The second category comprises countries that con- sume about as much as they produce, that is, so-called "balanced" tobacco economies. The third category consists of countries that consume more than they produce, meaning net and full importers. The latter category includes the highest number of countries by far, encompassing countries such as Indo- nesia, Nepal, and Vietnam. For the biggest group of countries, net and full importers, much of the impact of tobacco controls is borne by consumers, and more jobs are likely to be created than are lost (Table 6. 1). However, the small number of agrar- ian countries that are heavily dependent on tobacco could experience net national job losses. Among the worst-affected producer countries would 70 CURBING THE EPIDEMIC be those that export most of their crop, such as Malawi and Zimbabwe. One model suggests that in Zimbabwe, if all domestic tobacco farming stopped tomorrow, there would be a net loss of 12 percent of jobs. It should be stressed, however, that such an extreme scenario is unlikely. At the level of households and small rural communities, such adjust- ment would mean loss of income, upheaval, and possibly relocation, and many governments would consider it important to help ease the transition process (see Box 6.1).

THE COSTS AND CONSEQUENCES OF TOBACCO CONTROL 71 BOX 6.1 HELP FOR THE POOREST FARMERS There is little prospect of a sharp and sudden reduction in tobacco production. As the previous chapter showed, it is highly unlikely that supply-side policies to restrict tobacco production would be practicable or politically acceptable for the majority of countries. If demand for tobacco falls, meanwhile, it will fall slowly, allowing for an equally slow process of adjustment for those most di- rectly affected. An accurate assessment of the way in which gradually falling demand will affect tobacco-farming communities is clearly critical for policymakers. Stud- ies in most high-income countries suggest that the economies of these coun- tries' tobacco-growing areas have become gradually diversified. In high-income countries, tobacco farmers have been making economic adjustments for de- cades, and many tobacco farm communities can draw on more diversified economies today than in the past. Interest in further diversification is common. A recent survey of tobacco farmers in the United States indicates, for example, that half of those questioned were at least aware of profitable alternative agri- cultural activities being pursued by other tobacco farmers in their own coun- ties. Younger and more educated farmers were more likely than older farmers to be interested in diversification, and more likely to view diversification as possible. Likewise, a sizable minority of farmers questioned in the survey were aware of the prospect of change but recognized that it would be slow. Although more than eight out of 10 said that they personally expected to remain in to- bacco farming, one in three said they would advise their children not to remain in the same business. Nonetheless, there are several reasons why governments would want to provide assistance to meet the transition costs for their poorest farmers. Farms are a major source of rural employment and are often viewed as socially important by many societies. In addition, farmers can represent significant political opposition to tobacco control. Appropriate action for governments would involve a number of different efforts, such as encouraging sound agri- cultural and trade policies, the provision of broad rural development programs, assistance with crop diversification, rural training, and other safety-net sys- tems. Some governments have proposed that such support could be financed out of tobacco taxes. Governments may also learn from the success of local efforts. In the United States, for instance, some rural communities that are traditionally dependent on tobacco have formed coalitions with public health constituencies to agree upon core principles for policies that will reduce to- bacco consumption and also promote sustainable rural communities. 72 CURBING THE EPIDEMIC Will higher tobacco taxes reduce government revenues? Policymakers frequently argue against raising tobacco taxes on the basis that the resulting reduction in demand will cost governments vital revenue. In fact, the reverse is true in the short to medium term, even though the situation in the very long term is less certain. Tax revenues can be expected to rise in the short to medium term because, although higher prices clearly reduce consumption, the demand for cigarettes is relatively inelastic. So cigarette consumption will fall, but by a smaller proportion than prices will rise. In the United Kingdom, for example, cigarette taxes have been raised repeatedly over the past three decades. Partly because of these increases, and partly because of the steady increase in awareness about the health consequences of smoking, consump- tion has declined sharply over the same period, with the annual number of cigarettes sold falling from 138 billion to 80 billion over three decades. Rev- enues, however, are still rising. For every tax increase of 1 percent in the United Kingdom, government revenues increase by between 0.6 and 0.9 percent (see Figure 6. 1). A model developed for this study concludes that modest increases in cigarette excise taxes of 10 percent worldwide would increase tobacco tax revenues by about 7 percent overall, with the effects varying by country. Some nonprice measures, such as advertising and promotion bans, mass information, and warning labels, would be expected to reduce revenue. Inter- ventions to liberalize nicotine replacement therapy and other cessation efforts would also reduce consumption, and thus revenue. However, any such impact on revenue would be gradual, and a comprehensive control package that in- cludes tax increases is in any case likely to lead to net revenue increases. It is of course important to recognize that, if the ultimate aim of tobacco control is to benefit human health, then ideally the policymaker might wish to see tobacco consumption fall to such low levels that, eventually, tobacco tax revenues would begin to fall, too. This ultimate loss of revenue could be con- sidered as the measure of success of tobacco control-or society's willingness to pay for the health benefits of reduced smoking. But this is a theoretical possibility rather than a probable scenario. Based on current pattems, the number of smokers is expected to grow in low-income countries over the next three decades. Equally important, governments would be free to introduce an alter- native income tax or consumption tax that would replace the revenue from tobacco taxes. Will higher tobacco taxes cause massive increases in smuggling? It has been argued that higher taxes will contribute to increased cigarette smug- gling and associated criminal activity. In this scenario cigarette consumption will remain high and tax revenues will fall. However, econometric and other THE COSTS AND CONSEQUENCES OF TOBACCO CONTROL 73 FIGURE 6.1 AS TOBACCO TAX RISES, REVENUE RISES TOO Real price and tobacco taxation revenue in the U.K., 1971-95 9000 £3.00 .@ 8500 -TAX REVENUE ,_ £ 2.80 5 75000- - £20c -o 6500 PCE 2.60 C 8000 197 19417 9018 9618 9219 a~~~~~~~~Ya £ 2.40 Sore Toned o."h oeo aainPliyi oac oto. nAein .

South Africa: Applied Fiscal Research Centre, University of Cape Town. analyses of the experience of a large number of high-income countries show that, even in the face of high rates of smuggling, tax increases bring increased revenues and reduce cigarette consumption. Therefore, while smuggling is undoubtedly a serious problem, and while steep differentials in tobacco tax rates between countries are an incentive to smugglers, the appropriate response to smuggling is not to reduce tax rates or forego tax increases. Instead, it is more appropriate to crack down on crime. A second logical conclusion is that harmonization in cigarette tax rates between neighboring countries will help to reduce the incentives to smuggle. Canada's experience illustrates these points clearly. In the early 1980s and 1990s, Canada increased its cigarette taxes sharply so that the real price rose significantly. Between 1979 and 1991 teenage smoking fell by nearly two-thirds, adult smoking declined, and cigarette tax revenues rose substan- tially. However, because of concerns about greatly increased smuggling, the government cut cigarette taxes sharply. In response, the prevalence of smok- ing climbed in teenagers, and also increased again in the population as a whole. Meanwhile federal tobacco tax revenues fell by more than twice as much as predicted. 74 CURBING THE EPIDEMIC The experience of South Africa is also illuminating. During the 1990s, South Africa increased its excise taxes on cigarettes sharply, by more than 450 percent. As a percentage of sale price, taxation rose from 38 to 50 percent. Not surprisingly, smuggling rose, too, from zero to about 6 percent of the market, the global average. Sales fell by more than 20 percent, implying a significant net fall in consumption even with increased smuggling. Meanwhile, total tax revenues more than doubled in real terms. An econometric study assessed the potential impact of various different tax scenarios on the incentive for cigarette smuggling between countries in Europe. The analysis concluded that, even with rates of smuggling several times higher than those reported in Europe, higher taxes would still result in larger overall revenues. The study concluded that smuggling induced by price rises is likely to be a more significant problem in countries whose cigarettes are already priced high. Smuggling to countries with relatively cheap ciga- rettes would be relatively unaffected by price increases. Will poor consumers bear the heaviestfinancial burden? In many societies, there is a consensus that tax systems should be equitable, in the sense that those individuals with the greatest ability to pay should be taxed most heavily. This consensus is reflected, for example, in progressive income tax systems, where the marginal rates of tax rise as incomes rise. Tobacco taxes, however, are regressive, that is, like other consumption taxes on con- sumer goods, they place a disproportionately heavy financial burden on people with low incomes. This regressivity is further increased due to the fact that smoking is more common in poor households than rich households, so that poor smokers spend a larger share of their income on cigarette tax than do rich smokers. There is concern that, as taxes are raised, poor consumers will spend more and more of their income on cigarettes, resulting in significant family hard- ship. Even with contracted demand, it is true that if poor consumers continue to consume more tobacco than the rich, they will also pay more tax. However, numerous studies show that people on lower incomes are more responsive to price changes than people on high incomes. As their consumption falls more steeply, their relative tax burden will fall compared with that of the richer consumer, even though their absolute payments will still be greater. Two stud- ies from the United Kingdom and the United States support the idea of to- bacco tax increases being progressive, even though tobacco tax in itself is regressive. Further studies in low- and middle-income countries are required to confirm this finding. Of course, all individual smokers will have to forego the perceived benefits of smoking and suffer the costs of withdrawal, and these losses will be comparatively greater for poor consumers. THE COSTS AND CONSEQUENCES OF TOBACCO CONTROL 75 Tobacco taxes, like any other single tax, need to work within the goal of ensuring that the entire system of tax and expenditure is proportional or pro- gressive. Currently, the tax systems of most countries are a mix of many differ- ent taxes, where the overall goal is to be progressive or proportional, even though there may be individual taxes or elements of the system that are regres- sive. To offset the regressivity of a tobacco tax, governments could introduce more progressive taxes or other transfer programs. Provision of well-targeted social services, such as education and health programs, would tend to offset the regressivity of tobacco taxation. While in principle public benefits should be financed out of general rev- enues, the unique ability of tobacco taxation to raise revenues cannot be ig- nored. In China, estimates suggest that a 10 percent increase in cigarette tax would decrease consumption by 5 percent and increase revenue by 5 percent, making the increase sufficient enough to finance a package of essential health services for one-third of China's poorest 100 million citizens. Will tobacco control impose costs on7 individuals? By reducing cigarette consumption, tobacco control measures will reduce the satisfaction, or benefits, of the smoker-just as curtailed consumption of any other consumer good reduces consumers' welfare. Regular smokers must ei- ther forego the pleasure of smoking, or incur the costs of quitting, or both. This is a loss of consumer surplus, and must be set against the gains of tobacco control. However, as we saw earlier, tobacco is not a typical consumer good with typical benefits because of addiction and information problems. For the ad- dicted smoker who regrets smoking and expresses a desire to quit, the benefits of smoking probably include the avoidance of withdrawal. If tobacco control measures reduce individual smokers' consumption, those smokers will face significant withdrawal costs. Given that most regular smokers express a desire to quit but few are suc- cessful on their own, it seems likely that the perceived costs of quitting are greater than the perceived costs of continuing to smoke, such as damage to health. By making the costs of continued smoking greater than the costs of withdrawal, higher taxes can induce some smokers to quit. However, these smokers would still face withdrawal costs. Provision of information about the health consequences of smoking would increase the perceived costs of con- tinuing to smoke, and alert smokers to the benefits of quitting. Widened access to nicotine replacement therapy (NRT) and other cessation interventions would help to reduce the costs of quitting. It might be argued that tobacco control measures will impose bigger costs on poor individuals than on those with higher incomes. But if this is true for 76 CURBING THE EPIDEMIC tobacco, it is certainly not unique in the field of public health. Compliance with many health interventions, such as child immunization or family plan- ning, is often more costly for poor households. For example, poor families may have to walk longer distances to clinics than rich families, and may lose income in the process. Yet health officials do not usually hesitate to argue that the health benefits of most interventions, such as immunization, are worth the cost, provided the costs do not rise so high that poorer individuals are deterred from using services. In considering the loss of consumer surplus to smokers, it is important to distinguish between regular smokers and others. For children and adolescents who are either beginners or merely potential smokers, the costs of avoiding tobacco are likely to be less severe, since addiction may not yet have taken hold and therefore withdrawal costs should be minimal. Other costs may in- clude, for example, reduced acceptance by peers, less satisfaction from rebel- ling against parents, and the curtailment of other pleasures of smoking. Restrictions on smoking in public places and private workplaces also im- pose costs on smokers by forcing them outdoors to smoke or reducing their opportunities to smoke. These interventions would appropriately shift the costs of smoking from nonsmokers to smokers. Again, for some, this increase in costs will lead them to change their smoking patterns and will impose costs. For nonsmokers, however, tobacco control policies will bring welfare gains. Clearly, welfare losses are likely to be minimized if control interventions are implemented as a package. Is tobacco control worth paying for? We now ask whether tobacco control is cost-effective relative to other health interventions. For governments considering intervention, such information may be a further important factor in deciding how to proceed. The cost-effectiveness of different health interventions can be evaluated by estimating the expected gain in years of healthy life that each will achieve in return for the requisite public costs needed to implement that intervention. According to the World Bank's 1993 World Development Report, Investing in Health, tobacco control policies are considered cost-effective and worthy of inclusion in a minimal package of healthcare. Existing studies suggest that policy-based programs cost about $20 to $80 per discounted year of healthy life saved (one disability-adjusted life year, or DALY).' For this study, estimates were made of the cost-effectiveness of each of the demand-reducing interventions discussed in chapter 4: tax rises, a package of nonprice measures including advertising and promotion bans, wider health information and public smoking restrictions, and NRT. The findings may be of particular value to low- and middle-income countries in assessing the relative THE COSTS AND CONSEQUENCES OF TOBACCO CONTROL 77 emphases on specific interventions that are likely to be appropriate for their own needs. The estimates were made within the model described in Box 4.1. The model's assumptions and inputs are described in full in a background paper to this report. Some of the interventions, such as raising taxes or banning adver- tising and promotion, have zero or minimal costs, as these are "stroke-of-the pen" interventions. To be conservative, the model assigned substantial imple- mentation and administrative costs, along with drug costs for NRT. These costs do not, however, include possible costs borne by individuals. The results (Table 6.2) suggest that tax increases are by far the most cost-effective intervention. and one that compares favorably with many health interventions. Depending on the assumptions made about the administrative costs of raising and moni- toring higher tobacco taxes, the cost of implementing a tax increase of 10 percent could be less than $5 per DALY (and would be unlikely to be more than $17 per DALY) in low- and middle income countries. This represents cost-effectiveness values comparable to many health interventions financed by governments, such as child immunization. Nonprice measures may also be highly cost-effective for low- and middle-income countries. Depending on the assumptions on which the estimates are based, a package could be delivered for as little as $68 per DALY. This level of cost-effectiveness compares rea- sonably with several established interventions in public health, such as the package for the integrated management of the sick child, which has been esti- mated to cost between $30 and $50 per DALY in low-income countries and between $50 and $100 in middle-income countries.

Effectiveness anid Cost-effectiveness of Price Increases and Other Tobacco Conitrol Policy Interventions. Background paper. 78 CURBING THE EPIDEMIC The study also assessed the likely cost-effectiveness of widening access to NRT. For these estimates, it was assumed that the cost of NRT would be met from public funds. The results suggest that governments would need to exer- cise suitable caution in conducting local cost-effectiveness analyses before considering direct public provision of these new therapies. It is important to note that liberalizing access alone is far more likely to be cost-effective, and that as effectiveness and the numbers of adults wishing to quit grows, so would the cost-effectiveness of NRT improve. More research is clearly needed to identify the effectiveness of such pack- ages, their likely cost-effectiveness in countries of different income levels, and the costs to individuals. There are only rudimentary estimates of the costs of implementing a com- prehensive tobacco control program. The evidence from the high-income coun- tries suggests that such comprehensive programs can be delivered for very small sums of money. High-income countries with very comprehensive pro- grams spend between 50t and $2.50 per capita per year on these programs. In this context, tobacco control in low-income and middle-income countries is likely to be affordable, even in countries where per capita public expenditure on health is extremely low. The World Bank's 1993 World Development Re- port, Investing in Health, estimated that to deliver an essential package of pub- lic health interventions that includes tobacco control, governments would need to spend $4 per capita in low-income countries and $7 in middle-income coun- tries. As a fraction of the total, tobacco control would be small. Note I. A disability-adjusted year (DALY) is a time-based measure that allows epidemiolo- gists to capture in a single indicator the years of life lost to premature death (where premature death is defined as one that occurs before the age to which the dying person could have expected to survive if they were a member of a standardized model popu- lation with a life expectancy at birth equal to that of the world's longest-living popula- tion, in Japan) and years lived with a disability of a given severity and duration. One DALY is one lost year of healthy life. CHAPTER 7 An Agenda for Action ONLY two causes of death are large and growing worldwide: HIV and tobacco. While most countries have begun, at least, to respond to HIV, the response to the global tobacco epidemic has so far been limited and patchy. In this chapter, we discuss some of the factors that might influence governments' decisions to act and propose an agenda for effective action. All governments recognize that, in forming their policies, they take ac- count of many factors, and not only economics. Tobacco control policies are no exception. Most societies are concerned about protecting children, although the degree to which this is true varies from culture to culture. Most societies would wish to reduce the suffering and emotional losses wrought by tobacco's burden of disease and premature death. Economic studies have not yet brought any consensus to valuing that burden. For the policymaker seeking to improve pub- lic health, tobacco control is an attractive option. Even modest reductions in a disease burden of such large size would bring highly significant health gains. The consensus between societies that health gains are desirable is reflected in the tobacco policies and actions of the World Health Organization and in other international organizations (see Boxes 7.1 and 7.2 and Appendix A). Many societies might consider that the strongest reason for acting to con- trol tobacco is to deter children and adolescents from smoking. However, as the discussion in chapter 3 made clear, interventions that would specifically target only the youngest consumers are unlikely to have the desired effect, while those interventions that are effective-principally taxation-will also affect adults. Similarly, interventions designed specifically to protect nonsmok- 79 80 CURBING THE EPIDEMIC ers would fail to protect most of them, and, once again, taxation would be the most effective option. In the context of real policymaking, many societies would consider the broader effects of these policies to be acceptable and, in prag- matic terms, even desirable. In any case, any tobacco control policy whose effect was solely to deter children from starting to smoke would have no im- pact on global smoking-related deaths for many decades, since most of the projected deaths for the first half of the next century are those of existing smokers (Figure 7.1). Therefore, governments concemed with health gains in the me- dium term would likely wish to encourage adults to quit also.

AN AGENDA FOR ACTION 81 Overcoming political barriers to change To be effective, any government that decides to implement tobacco controls must do so in a context in which the decision has broad popular support. While it might seem that smokers would be strongly opposed to tobacco control, the reality is rather different: in studies of high-income countries with successful tobacco control programs, most adult smokers have been found to support at least some controls, such as widely available information. Governments alone cannot achieve success without the involvement of civil society, the private sector, and interest groups. Programs are more likely to succeed if there is collective agreement in and ownership of them across a broad coalition of social interests with the power to implement and sustain change. There have been few attempts to quantify the combined impact of a mix of interventions. As chapter 4 showed, each individual intervention is capable of preventing millions of deaths, but whether a package of measures would save even more lives than the sum of each individual intervention together is as yet unknown. In implementing a package, each country would probably give different emphasis to different interventions, depending on the country's circumstances. For example, a country whose cigarette tax rates are currently lower than those of its neighbors is likely to see a particularly strong effect of tax increases on cigarette consumption. Similarly, a relatively well-educated and affluent population will respond less to price, and more to new informa- tion, than less educated and poorer populations. Cultural factors, such as a history of totalitarian rule, might also affect the ease with which some mea- sures, such as smoking bans in public places, are accepted. These generaliza- tions are simplistic, but policymakers may find them a useful starting point. Governments contemplating action to control tobacco face major political obstacles to change. Yet, by identifying the key stakeholders on both the supply and demand sides in each country, policymakers can assess the size of each constituency, whether it is dispersed or concentrated, and other factors that may affect the constituency's response to change. For example, policymakers might note that winners, such as nonsmokers, may be a scattered and dispersed group, while losers, such as tobacco farmers, may have a powerful political and emo- tional voice. Careful planning and political mapping would be essential to achieve a smooth transition from reliance on tobacco to independence from it, whatever the nature of the economy and the national political framework. Such mapping exercises have been conducted, for example, in Vietnam. Research priorities Demand-reducing measures such as higher taxes and bans on advertising and pro- motion have already been seen to work in high-income countries, and enough is 82 CURBING THE EPIDEMIC known already to implement these measures without delay. At the same time, how- ever, a concurrent research agenda, both in epidemiology and economics, will be needed to help governments to adjust their packages of interventions to achieve the greatest chance of success. Some key research areas are outlined below. Research into the causes, consequences, and costs of smoking at national and regional levels Research is needed at national and regional levels to "count the tobacco dead" and classify deaths by cause. A simple and low-cost measure is to place ques- tions on past smoking on death certificates, permitting comparisons of smoking excess among tobacco-attributable and other deaths. The benefits of such re- search go farther than their practical value of informing governments of the status of their tobacco epidemic or a baseline against which to monitor the impact of control efforts. They stimulate policy responses and may have a sig- nificant impact on tobacco consumption. While epidemiological research into the consequences of smoking has at least begun to spread outside the high-income countries, research into the causes of smoking, the addictive nature of tobacco use, and the behavioral factors associated with smoking uptake remains heavily biased toward North America and Western Europe. While control interventions are being implemented, par- allel research activities into these issues may help to refine the targeting of interventions, such as those designed to improve health information for the poor, for maximum effect. For economists, research into the cost-effectiveness of each intervention at the national level is also a priority. Further data on price elasticity in low- and middle-income countries would be valuable, as would estimates of the social and healthcare costs of tobacco use in these countries. Research into tobacco control has received less funding than might be ex- pected in light of the size of the disease burden of smoking. During the early 1990s, the most recent time period for which data are available, investment in research and development in tobacco control amounted to $50 per 1990 death (a total of $148-$164 million). In contrast, HIV research and development re- ceived about $3,000 per 1990 death (a total of $919-$985 million). Spending on both diseases is concentrated primarily in high-income countries. Recommendations This report makes two recommendations: 1. Where governments decide to take strong action to curb the tobacco epidemic, a multipronged strategy should be adopted. Its aims should be to deter children from smoking, to protect nonsmokers, and to pro- AN AGENDA FOR ACTION 83 vide all smokers with information about the health effects of tobacco. The strategy, tailored to individual country needs, would include: (1) raising taxes, using as a yardstick the rates adopted by countries with comprehensive tobacco control policies where consumption has fallen. In these countries, tax accounts for two-thirds to four-fifths of the re- tail price of cigarettes; (2) publishing and disseminating research re- sults on the health effects of tobacco, adding prominent warning labels to cigarettes, adopting comprehensive bans on advertising and promo- tion, and restricting smoking in workplaces and public places; and (3) widening access to nicotine replacement and other cessation therapies. 2. Inzternzational organizations such as the United Nations agencies should review their existing programs and policies to ensure that tobacco con- trol is given due prominence; they should sponsor research into the causes, consequences, and costs of smoking, and the cost-effective- ness of interventions at the local level; and they should address to- bacco control issues that cross borders, including working with the WHO's proposed Framework Convention for Tobacco Control. Key areas for action include facilitating international agreements on smug- gling control, discussions on tax harmonization to reduce the incen- tives for smuggling, and bans on advertising and promotion involving the global communications media. The threat posed by smoking to global health is unprecedented, but so is the potential for reducing smoking-related mortality with cost-effective poli- cies. This report shows the scale of what might be achieved: moderate action could ensure substantial health gains for the 21 st century.

APPENDIX A Tobacco Taxation: A View from the International Monetary Fund INCREASES in tobacco excise rates are often included as a compo- nent of Fund-supported stabilization programs for countries that need to mobi- lize additional tax revenue to reduce the fiscal deficit. While excise rates on tobacco products may be increased primarily to raise revenue, there are also health benefits from reduced tobacco consumption. In setting tobacco tax rates, governments need to take into account several factors, including the impact of smuggling, cross-border shopping, and duty- free purchases on ferries and planes. It is in the interest of governments to reduce tobacco smuggling not only to increase excise revenues but also to limit the loss of revenues from other taxes, including income and value-added taxes, as underground transactions replace legal ones. Ultimately, tobacco ex- cise tax rates must reflect the purchasing power of the local consumers, rates in neighboring countries, and, above all, the ability and willingness of the tax authority to enforce compliance. With respect to the structure of tobacco excises, countries should tax all types of tobacco-cigarettes, cigars. pipe tobacco, snuff or chewing tobacco, and hand-rolling tobacco. The best international practice is to impose excises on the destination basis under which imports are taxed and exports are freed of tax. Excises can be either specific taxes (based on quantity) or ad valorem (based on value). If a primary purpose of the excise is to discourage tobacco consumption, a strong case can be made for specific excises that would im- pose the same tax per stick. Specific taxes also are easier to administer be- 87 88 CURBING THE EPIDEMIC cause it is only necessary to determine the physical quantity of the product taxed, and not necessary to determine its value. Ad valorem taxes, however, may keep pace with inflation better than specific taxes, even specific taxes that are adjusted fairly frequently. The administration of domestic tobacco excises requires an integrated strat- egy for taxpayer registration; filing and payment; collection of overdue taxes; audit; and taxpayer services. Developing and transition countries may need to treat tobacco production facilities as extraterritorial and administer excises simi- lar to customs duties. The tax authority would control shipments into and out of the production facility. Excise stamps can assist in ensuring the payment of excises and ensur- ing that goods that have paid the tax appropriate for one jurisdiction are not shipped to another. Introduction of stamps, however, involves considerable costs for producers of excised goods. Stamps will serve little purpose in con- trol unless their utilization is monitored at the retail level.
