Tobacco use is the leading cause of preventable death in United States, causing more than 440,000 deaths annually and resulting in $193 billion in health-related economic losses each year-$96 billion in direct medical costs and $97 billion in lost productivity. Since the first U.S. Surgeon General's report on smoking in 1964, more than 29 Surgeon General's reports, drawing on data from thousands of studies, have documented the overwhelming and conclusive biologic, epidemiologic, behavioral, and pharmacologic evidence that tobacco use is deadly. This evidence base links tobacco use to the development of multiple types of cancer and other life-threatening conditions, including cardiovascular and respiratory diseases. Smoking accounts for at least 30 percent of all cancer deaths, and 80 percent of lung cancer deaths. Despite the widespread agreement on the dangers of tobacco use and considerable success in reducing tobacco use prevalence from over 40 percent at the time of the 1964 Surgeon General's report to less than 20 percent today, recent progress in reducing tobacco use has slowed. An estimated 18.9 percent of U.S. adults smoke cigarettes, nearly one in four high school seniors smoke, and 13 percent of high school males use smokeless tobacco products. In recognition that progress in combating cancer will not be fully achieved without addressing the tobacco problem, the National Cancer Policy Forum of the Institute of Medicine (IOM) convened a public workshop, Reducing Tobacco-Related Cancer Incidence and Mortality, June 11-12, 2012 in Washington, DC. In opening remarks to the workshop participants, planning committee chair Roy Herbst, professor of medicine and of pharmacology and chief of medical oncology at Yale Cancer Center and Smilow Cancer Hospital, described the goals of the workshop, which were to examine the current obstacles to tobacco control and to discuss potential policy, outreach, and treatment strategies that could overcome these obstacles and reduce tobacco-related cancer incidence and mortality. Experts explored a number of topics, including: the changing demographics of tobacco users and the changing patterns of tobacco product use; the influence of tobacco use on cancer incidence and cancer treatment outcomes; tobacco dependence and cessation programs; federal and state level laws and regulations to curtail tobacco use; tobacco control education, messaging, and advocacy; financial and legal challenges to tobacco control efforts; and research and infrastructure needs to support tobacco control strategies, reduce tobacco related cancer incidence, and improve cancer patient outcomes. Reducing Tobacco-Related Cancer Incidence and Mortality summarizes the workshop.

The health and economic costs of tobacco use in military and veteran populations are high. In 2007, the Department of Veterans Affairs (VA) and the Department of Defense (DoD) requested that the Institute of Medicine (IOM) make recommendations on how to reduce tobacco initiation and encourage cessation in both military and veteran populations. In its 2009 report, Combating Tobacco in Military and Veteran Populations, the authoring committee concludes that to prevent tobacco initiation and encourage cessation, both DoD and VA should implement comprehensive tobacco-control programs.

Tobacco use by adolescents and young adults poses serious concerns. Nearly all adults who have ever smoked daily first tried a cigarette before 26 years of age. Current cigarette use among adults is highest among persons aged 21 to 25 years. The parts of the brain most responsible for cognitive and psychosocial maturity continue to develop and change through young adulthood, and adolescent brains are uniquely vulnerable to the effects of nicotine. At the request of the U.S. Food and Drug Administration, Public Health Implications of Raising the Minimum Age of Legal Access to Tobacco Products considers the likely public health impact of raising the minimum age for purchasing tobacco products. The report reviews the existing literature on tobacco use patterns, developmental biology and psychology, health effects of tobacco use, and the current landscape regarding youth access laws, including minimum age laws and their enforcement. Based on this literature, the report makes conclusions about the likely effect of raising the minimum age to 19, 21, and 25 years on tobacco use initiation. The report also quantifies the accompanying public health outcomes based on findings from two tobacco use simulation models. According to the report, raising the minimum age of legal access to tobacco products, particularly to ages 21 and 25, will lead to substantial reductions in tobacco use, improve the health of Americans across the lifespan, and save lives. Public Health Implications of Raising the Minimum Age of Legal Access to Tobacco Products will be a valuable reference for federal policy makers and state and local health departments and legislators.

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Data suggest that exposure to secondhand smoke can result in heart disease in nonsmoking adults. Recently, progress has been made in reducing involuntary exposure to secondhand smoke through legislation banning smoking in workplaces, restaurants, and other public places. The effect of legislation to ban smoking and its effects on the cardiovascular health of nonsmoking adults, however, remains a question. Secondhand Smoke Exposure and Cardiovascular Effects reviews available scientific literature to assess the relationship between secondhand smoke exposure and acute coronary events. The authors, experts in secondhand smoke exposure and toxicology, clinical cardiology, epidemiology, and statistics, find that there is about a 25 to 30 percent increase in the risk of coronary heart disease from exposure to secondhand smoke. Their findings agree with the 2006 Surgeon General's Report conclusion that there are increased risks of coronary heart disease morbidity and mortality among men and women exposed to secondhand smoke. However, the authors note that the evidence for determining the magnitude of the relationship between chronic secondhand smoke exposure and coronary heart disease is not very strong. Public health professionals will rely upon Secondhand Smoke Exposure and Cardiovascular Effects for its survey of critical epidemiological studies on the effects of smoking bans and evidence of links between secondhand smoke exposure and cardiovascular events, as well as its findings and recommendations.
