The goal of policy interventions on smoking is to reduce as rapidly as possible the incidence of death and disease related to smoking. Toward that end, policy measures employ a four-part strategy: (1) discourage individuals from starting to use tobacco, (2) encourage users to quit and provide support for their efforts, (3) reduce the adverse health consequences of tobacco by substantially reducing the toxins to which users are exposed through their use of tobacco products, and (4) expand clean-air nonsmoking policies to protect nonsmokers and to support prevention and cessation efforts.

No single action can accomplish these goals, but the coordination of a number of actions has proved effective in reducing tobacco use in a number of countries. These actions, encouraged by WHO, include:

• Reducing access to tobacco products by prohibiting sales to minors, raising prices, and making them more difficult to purchase.
• Promoting educational campaigns that provide detailed health information and ensuring that tobacco products include appropriate health warnings and information on how to get help in quitting.
• Restricting smoking in public areas and the workplace in order to protect nonsmokers. This action also has the effect of making it difficult to smoke and increases the pressure on smokers to quit.
• Regulating product manufacture to minimize the health risks to which tobacco users are exposed.

These goals and strategies may seem simple, but they are complex in practice because of opposition by the tobacco industry, merchants, and benefactors of tobacco sales. Furthermore, users of tobacco tend to find many reasons to keep using it and to oppose efforts to restrict it. Controlling access to tobacco products involves balancing efforts to prevent young people and nonusers from becoming tobacco users while continuing to make the products available to users. Efforts to inform consumers more thoroughly about the risks of use and the benefits of nonuse raise practical questions of how this information can be communicated most effectively to the consumer and what role, if any, the manufacturers should have in communicating such information.

Regulation

Regulation of the design and ingredients of tobacco products is perhaps the greatest challenge for tobacco-control advocates. In the United States the Food and Drug Administration in 1996 attempted to regulate tobacco and its marketing—without banning it—in such a way that would reduce smokers’ risks of developing a nicotine addiction and increase their likelihood of quitting. Key elements of the regulation were increased restrictions on appeal-enhancing marketing and reduced access by young people to tobacco products. Although this regulatory effort was overturned by the U.S. Supreme Court in 2000, the court recognized that some form of substantial regulation was not prohibited by the Constitution. The FDA was given the authority to regulate tobacco products in 2009.

The need to protect nonsmokers from the health risks of environmental tobacco smoke has led to stricter regulation of smoking in public places, such as airports and hotels, and even to citywide and countrywide bans on smoking in enclosed workplaces, including offices, restaurants, and taverns. Although the primary purpose of smoking restrictions is to prevent nonsmokers from being exposed to environmental tobacco smoke, a major public health benefit is that such restrictions put pressure on smokers to quit and, in general, act as a deterrent to smoking.

Taxation

Price has likely been the single most effective policy intervention by those seeking to reduce tobacco-caused death and disease. Detailed studies have shown that in many countries price increases cause many smokers to quit and others to reduce their smoking. The smoking practices of young people have been shown to be particularly sensitive to price. For example, between 1982 and 1992 Canada raised the real price of tobacco products by 150 percent. This price increase coincided with a reduction in total cigarette consumption of roughly 40 percent and a reduction in teenage smoking of 60 percent. In some countries, including Australia and France, increases in cigarette prices have been found to be a potent force for preventing young people from taking up tobacco and for supporting smoking-cessation efforts among adults.

Litigation against the tobacco industry

Litigation and the threat of litigation played a major role in shaping the environment for tobacco products at the end of the 20th century. While litigation seeks to accomplish the same ends as legislation, it is often a more viable strategy in regions where legislators are reluctant to act against the interests of the tobacco industry and its frequent allies, such as convenience stores and the alcohol-selling portions of the hospitality industry, which rely heavily on tobacco sales for their total revenue.

Litigation covers a wide range of issues, including product liability, consumer protection, antitrust activity, racketeering, health care reimbursement, and tax evasion. These lawsuits have been brought forward by individuals, classes of individuals (class actions), governments, and others. The ability of plaintiffs to sue tobacco companies for health care reimbursement is based on various legal theories of recovery, including negligence, gross negligence, strict liability, fraud, misrepresentation, design defect, failure to adequately warn, and conspiracy. In a landmark 1998 case, the major cigarette companies in the United States entered into an agreement with the attorneys general of a number of states as a result of lawsuits aimed at recouping health care expenditures for treating sick smokers. This agreement required the disclosure of millions of corporate documents, the discontinuation of various forms of youth-focused advertising, and the annual payment in perpetuity of roughly $10 billion per year. Although the actual payment may vary and even decrease as cigarette consumption decreases, such a substantial amount has put pressure on tobacco companies to support legislative efforts they formerly opposed, since further litigation could bankrupt them.
