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.

Negative Affective States and Cognitive Impairments in Nicotine Dependence is the only book of its kind that addresses nicotine use and abuse in the context of negative reinforcement mechanisms. Written and edited by leading investigators in addiction, affective, genetic, and cognitive research, it provides researchers and advanced students with an overview of the clinical bases of these effects, allowing them to fully understand the various underlying dysfunctions that drive nicotine use in different individuals. In addition, this book examines animal models that researchers have utilized to investigate the biological bases of these dysfunctions. The combination of clinical and preclinical approaches to understanding nicotine dependence makes this book an invaluable resource for researchers and practitioners seeking to develop targeted treatments aimed at ameliorating symptoms of nicotine dependence, as well as identifying premorbid differences in affective or cognitive function. - Provides a unique perspective on nicotine dependence that emphasizes negative reinforcement rather than positive reinforcement - Examines psychiatric comorbidities and alleviation of withdrawal states as motivation for continued tobacco use - Includes both clinical and preclinical perspectives - Includes genetic and multi-neurotransmitter perspectives on nicotine use and withdrawal - Emphasizes heterogeneity of underlying reasons for smoking, the need for multiple animal models to understand this heterogeneity, and the expectation of heterogeneous responses to potential treatments, underscoring the need for personalized therapeutics

The primary purpose of this book and its companion volume The Behavioral Genetics of Nicotine and Tobacco is to explore the ways in which recent studies on nicotine and its role in tobacco addiction have opened our eyes to the psychopharmacological properties of this unique and fascinating drug. While The Behavioral Genetics of Nicotine and Tobacco considers the molecular and genetic factors which influence behavioral responses to nicotine and how these may impact on the role of nicotine in tobacco dependence, the present book focuses on the complex neural and psychological mechanisms that mediate nicotine dependence in experimental animal models and their relationship to tobacco addiction in humans. These volumes will provide readers a contemporary overview of current research on nicotine psychopharmacology and its role in tobacco dependence from leaders in this field of researchand will hopefully prove valuable to those who are developing their own research programmes in this important topic.

A comprehensive, up-to-date resource providing information about genetic influences on disorders of behavior.

The fact that tobacco ingestion can affect how people feel and think has been known for millennia, placing the plant among those used spiritually, honori?cally, and habitually (Corti 1931; Wilbert 1987). However, the conclusion that nicotine - counted for many of these psychopharmacological effects did not emerge until the nineteenth century (Langley 1905). This was elegantly described by Lewin in 1931 as follows: “The decisive factor in the effects of tobacco, desired or undesired, is nicotine. . . ”(Lewin 1998). The use of nicotine as a pharmacological probe to und- stand physiological functioning at the dawn of the twentieth century was a landmark in the birth of modern neuropharmacology (Limbird 2004; Halliwell 2007), and led the pioneering researcher John Langley to conclude that there must exist some “- ceptive substance” to explain the diverse actions of various substances, including nicotine, when applied to muscle tissue (Langley 1905). Research on tobacco and nicotine progressed throughout the twentieth century, but much of this was from a general pharmacological and toxicological rather than a psychopharmacological perspective (Larson et al. 1961). There was some attention to the effects related to addiction, such as euphoria (Johnston 1941), tolerance (Lewin 1931), and withdrawal (Finnegan et al. 1945), but outside of research supported by the tobacco industry, addiction and psychopharmacology were not major foci for research (Slade et al. 1995; Hurt and Robertson 1998; Henning?eld et al. 2006; Henning?eld and Hartel 1999; Larson et al. 1961).

Despite persistent warnings from the medical profession about the health risks involved in cigarette smoking, millions of people continue to smoke cigarettes. With contributions from renowned experts, this ground-breaking work defines and explains nicotine addiction as a primary problem or disease, instead of as a habit or risk factor for other diseases. A comprehensive, clinical text on tobacco dependence, this book provides clinicians with essential information on how to diagnose and treat nicotine addicted patients. It also offers the medical, epidemiological and behavioral science backgrounds necessary for understanding the process and dynamics of tobacco dependence. Following the traditional format of medical texts, the book first covers etiology, pathogenesis and complications, then diagnosis and treatment, and finally public health and prevention. Part One presents an overview of the biological, psychological and social factors that contribute to nicotine dependence including such topics as a description of nicotine delivery systems, psychopharmacology, economics, natural history and epidemiology, mortality, morbidity, and environmental tobacco smoke exposure. The second part offers practical guidelines and tools for treating nicotine dependence and describes a stepped-care treatment model with brief interventions that can be easily integrated into routine medical practice. This section also covers the role of psychopharmacologic and formal treatment programs, the treatment of smokeless tobacco addiction, and treating nicotine dependence in pregnant women and in people with medical illnesses, other chemical dependencies, or psychiatric disorders. The last section focuses on worksite and community intervention programs and summarizes the research on smoking patterns and history in women, Blacks, Hispanics, youth, and older adults, and shows how intervention and prevention programs could be made more effective in these groups. Written by the nation's leading tobacco control researchers and clinicians, this important work contains new and critical information not previously available.

The report "Offering help to quit tobacco use" tracks the status of the tobacco epidemic and interventions to combat it. The report finds that more countries have implemented tobacco control policies, ranging from graphic pack warnings and advertising bans to no smoking areas. About 5 billion people - 65% of the world's population - are covered by at least one comprehensive tobacco control measure, which has more than quadrupled since 2007 when only 1 billion people and 15% of the world's population were covered.
