Neuroscience Of Nicotine

Neuroscience of Nicotine: Mechanisms and Treatment presents the fundamental information necessary for a thorough understanding of the neurobiological underpinnings of nicotine addiction and its effects on the brain. Offering thorough coverage of all aspects of nicotine research, treatment, policy and prevention, and containing contributions from internationally recognized experts, the book provides students, early-career researchers, and investigators at all levels with a fundamental introduction to all aspects of nicotine misuse. With an estimated one billion individuals worldwide classified as tobacco users—and tobacco use often being synonymous with nicotine addiction—nicotine is one of the world’s most common addictive substances, and a frequent comorbidity of misuse of other common addictive substances. Nicotine alters a variety of neurological processes, from molecular biology, to cognition, and quitting is exceedingly difficult because of the number of withdrawal symptoms that accompany the process. Integrates cutting-edge research on the pharmacological, cellular and molecular aspects of nicotine use, along with its effects on neurobiological function Discusses nicotine use as a component of dual-use and poly addictions and outlines numerous screening and treatment strategies for misuse Covers both the physical and psychological effects of nicotine use and withdrawal to provide a fully-formed view of nicotine dependency and its effects

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).

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

Tobacco use kills more people than any other addiction and we know that addiction starts in childhood and youth. We all agree that youths should not smoke, but how can this be accomplished? What prevention messages will they find compelling? What effect does tobacco advertisingâ€"more than $10 million worth every dayâ€"have on youths? Can we responsibly and effectively restrict their access to tobacco products? These questions and more are addressed in Growing Up Tobacco Free, prepared by the Institute of Medicine to help everyone understand the troubling issues surrounding youths and tobacco use. Growing Up Tobacco Free provides a readable explanation of nicotine's effects and the process of addiction, and documents the search for an effective approach to preventing the use of cigarettes, chewing and spitting tobacco, and snuff by children and youths. It covers the results of recent initiatives to limit young people's access to tobacco and discusses approaches to controls or bans on tobacco sales, price sensitivity among adolescents, and arguments for and against taxation as a prevention strategy for tobacco use. The controversial area of tobacco advertising is thoroughly examined. With clear guidelines for public action, everyone can benefit by reading and acting on the messages in this comprehensive and compelling book.

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.

Neurobiology of Addiction is conceived as a current survey and synthesis of the most important findings in our understanding of the neurobiological mechanisms of addiction over the past 50 years. The book includes a scholarly introduction, thorough descriptions of animal models of addiction, and separate chapters on the neurobiological mechanisms of addiction for psychostimulants, opioids, alcohol, nicotine and cannabinoids. Key information is provided about the history, sources, and pharmacokinetics and psychopathology of addiction of each drug class, as well as the behavioral and neurobiological mechanism of action for each drug class at the molecular, cellular and neurocircuitry level of analysis. A chapter on neuroimaging and drug addiction provides a synthesis of exciting new data from neuroimaging in human addicts — a unique perspective unavailable from animal studies. The final chapters explore theories of addiction at the neurobiological and neuroadaptational level both from a historical and integrative perspective. The book incorporates diverse finding with an emphasis on integration and synthesis rather than discrepancies or differences in the literature. · Presents a unique perspective on addiction that emphasizes molecular, cellular and neurocircuitry changes in the transition to addiction · Synthesizes diverse findings on the neurobiology of addiction to provide a heuristic framework for future work · Features extensive documentation through numerous original figures and tables that that will be useful for understanding and teaching
