Answer:
The scope of the burden of disease and death that cigarette smoking imposes on the public's health is extensive. Cigarette smoking is the major focus of this chapter because it is the central public health problem, but the topics of secondhand smoke exposure, smoking of other combustible tobacco products, smokeless tobacco, and electronic nicotine delivery systems (ENDS) are also considered. The magnitude of the public health threat posed by cigarette smoking stems from two factors: (1) the prevalence of cigarette smoking is so high, and (2) smoking causes so many deleterious health effects. A policy change that reduces the prevalence of cigarette smoking will result in a commensurate reduction in the population burden of disease and death caused by cigarette smoking. The associations between cigarette smoking and the adverse health effects caused by smoking are dose-dependent (HHS, 2014). Thus, a public health benefit would be realized if a policy change led to reduced exposure to cigarette smoke via means other than reducing the prevalence of smoking. For example, additional reduction in the population burden of smoking-caused disease and death will be generated if the policy also results in delayed initiation of cigarette smoking. The population health benefit from delayed initiation, although potentially large, will be less than the benefit from a commensurate reduction in smoking prevalence because delayed initiation is associated with reduced exposure to cigarette smoking rather than with the complete prevention of the exposure. A decrease in the prevalence of cigarette smoking will have additional downstream benefits by reducing the potential for nonsmokers to be exposed to secondhand tobacco smoke.
