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.

This booklet for schools, medical personnel, and parents contains highlights from the 2012 Surgeon General's report on tobacco use among youth and teens (ages 12 through 17) and young adults (ages 18 through 25). The report details the causes and the consequences of tobacco use among youth and young adults by focusing on the social, environmental, advertising, and marketing influences that encourage youth and young adults to initiate and sustain tobacco use. This is the first time tobacco data on young adults as a discrete population have been explored in detail. The report also highlights successful strategies to prevent young people from using tobacco.

Tobacco use has declined because of measures such as high taxes on tobacco products and bans on advertising, but worldwide there are still more than one billion people who regularly use tobacco, including many who purchase products illicitly. By contrast to many other commodities, taxes comprise a substantial portion of the retail price of cigarettes in the United States and most other nations. Large tax differentials between jurisdictions increase incentives for participation in existing illicit tobacco markets. In the United States, the illicit tobacco market consists mostly of bootlegging from low-tax states to high-tax states and is less affected by large-scale smuggling or illegal production as in other countries. In the future, nonprice regulation of cigarettes - such as product design, formulation, and packaging - could in principle, contribute to the development of new types of illicit tobacco markets. Understanding the U.S. Illicit Tobacco Market reviews the nature of illicit tobacco markets, evidence for policy effects, and variations among different countries with a focus on implications for the United States. This report estimates the portion of the total U.S. tobacco market represented by illicit sales has grown in recent years and is now between 8.5 percent and 21 percent. This represents between 1.24 to 2.91 billion packs of cigarettes annually and between $2.95 billion and $6.92 billion in lost gross state and local tax revenues. Understanding the U.S. Illicit Tobacco Market describes the complex system associated with illicit tobacco use by exploring some of the key features of that market - the cigarette supply chain, illicit procurement schemes, the major actors in the illicit trade, and the characteristics of users of illicit tobacco. This report draws on domestic and international experiences with the illicit tobacco trade to identify a range of possible policy and enforcement interventions by the U.S. federal government and/or states and localities.

The story of tobacco’s rise and fall may seem simple enough—a tale of science triumphing over corporate greed—but the truth is more complicated. After the Great Depression, government officials and tobacco farmers worked hand in hand to ensure that regulation was used to promote tobacco rather than protect consumers. As evidence of the connection between cigarettes and cancer grew, scientists struggled to secure federal regulation in the name of public health. What turned the tide, Sarah Milov reveals, was a new kind of politics: a movement for nonsmokers’ rights. Activists took to the courts, the streets, city councils, and boardrooms to argue for smoke-free workplaces and allied with scientists to lobby elected officials. The Cigarette puts politics back at the heart of tobacco’s rise and fall, dramatizing the battles over corporate influence, individual choice, government regulation, and science. “A nuanced and ultimately devastating indictment of government complicity with the worst excesses of American capitalism.” —New Republic “An impressive work of scholarship evincing years of spadework...A well-told story.” —Wall Street Journal “If you want to know what the smoke-filled rooms of midcentury America were really like, this is the book to read.” —Los Angeles Review of Books

Tobacco use among youth and young adults in any form, including e-cigarettes, is not safe. In recent years, e-cigarette use by youth and young adults has increased at an alarming rate. E-cigarettes are now the most commonly used tobacco product among youth in the United States. This timely report highlights the rapidly changing patterns of e-cigarette use among youth and young adults, assesses what we know about the health effects of using these products, and describes strategies that tobacco companies use to recruit our nation's youth and young adults to try and continue using e-cigarettes. The report also outlines interventions that can be adopted to minimize the harm these products cause to our nation's youth.E-cigarettes are tobacco products that deliver nicotine. Nicotine is a highly addictive substance, and many of today's youth who are using e-cigarettes could become tomorrow's cigarette smokers. Nicotine exposure can also harm brain development in ways that may affect the health and mental health of our kids.E-cigarette use among youth and young adults is associated with the use of other tobacco products, including conventional cigarettes. Because most tobacco use is established during adolescence, actions to prevent our nation's young people from the potential of a lifetime of nicotine addiction are critical.E-cigarette companies appear to be using many of the advertising tactics the tobacco industry used to persuade a new generation of young people to use their products. Companies are promoting their products through television and radio advertisements that use celebrities, sexual content, and claims of independence to glamorize these addictive products and make them appealing to young people.
