Marijuana And Madness Psychiatry And Neurobiology

The second edition of this critically acclaimed and award-winning text provides a comprehensive overview of the psychiatry and neuroscience of Cannabis sativa (marijuana). It outlines the very latest developments in our understanding of the human cannabinoid system, and links this knowledge to clinical and epidemiological facts about the impact of cannabis on mental health. Clinically focused chapters review not only the direct psychomimetic properties of cannabis, but also the impact consumption has on the courses of evolving or established mental illnesses such as schizophrenia. Effects of cannabis on mood are reviewed, as are its effects on cognition. This new edition has been extensively updated and expanded with ten new chapters to incorporate major new research findings. This book will be of interest to all members of the mental health team, as well as to neuroscientists, epidemiologists, public health specialists and those involved in drug and alcohol research.

This comprehensive and up-to-date overview of the psychiatry and neuroscience of Cannabis sativa (marijuana) places particular emphasis on psychotic disorders. It outlines the latest research enhancing our knowledge of the human cannabinoid system, and links it to clinical and epidemiological facts about the impact of cannabis on mental health. Controversial issues are critically explored, including whether a discrete "cannabis psychosis" exists. - Publisher.

The Complex Connections between Cannabis and Schizophrenia provides an in-depth overview of the current state of research into the role that cannabis plays in schizophrenia, covering both the pathophysiological and the pharmacological implications. It addresses the epidemiology of cannabis use and the risks associated with its use, the biological aspects of the drug, its effects on the brain and the pharmacological possibilities of using cannabidiol to treat schizophrenia. It is the only book on the market devoted exclusively to examining the links between this very commonly used (and misused) drug and a specific set of devastating psychiatric illnesses, providing a comprehensive guide to our current understandings of this relationship. Marijuana is the most commonly used illicit drug globally, and is becoming increasingly decriminalized and even legalized worldwide. Among the numerous mental-health concerns related to the drug, there is mounting evidence of an intricate link between cannabis use and schizophrenia and related psychotic disorders. At the same time, there is promising evidence to suggest that cannabidiol, one of the many compounds found in cannabis that activates the brain’s cannabinoid receptors, could prove to be an effective antipsychotic to treat schizophrenia. Synthesizes existing knowledge about the confusing, but crucial, relationship between cannabis use and schizophrenia symptoms Provides a comprehensive overview of the neurobiological mechanisms of cannabis use and its effects on the brain, including an exploration of the endocannabinoid system Examines the promising evidence suggesting cannabidiol as an effective antipsychotic treatment for schizophrenia Aids readers studying the neurobiological underpinning of cannabis addiction and psychosis in determining directions for their own future research

Cannabis Use, Neurobiology, Psychology, and Treatment offers readers a comprehensive reference on neurological changes, both transient and long-term, and other factors surrounding the use of these compounds and extracts. With coverage of both natural and synthetic cannabinoids, this broad coverage allows readers to learn about both adverse and non-adverse effects, including reactivity to pain, changes in behavior, and neuroactivity. This volume provides a platform for research on the effects of these compounds in brain function and neurological dysfunction. Extracts from the Cannabis sativa plant contain scores of psychoactive compounds in addition to the principal agent tetrahydrocannabinol, many of which are neuroactive. Summarizes cannabis and cannabinoid research in relation to neurological function Contains chapter abstracts, key facts, a dictionary and a summary Covers the neuroactivity of multiple Cannabis compounds beyond tetrahydrocannabinol Includes conditions like depression, anxiety, Parkinson’s, psychosis, and epilepsy Discusses brain structure and brain development, including functional connectivity

This book provides a comprehensive overview of the psychiatry and neuroscience of Cannabis sativa (marijuana), with particular emphasis on psychotic disorders. It outlines developments in our understanding of the human cannabinoid system, and links this knowledge to clinical and epidemiological facts about the impact of cannabis on mental health. Clinically focused chapters review not only the direct psychomimetic properties of cannabis, but also the impact consumption has on the courses of evolving or established mental illness such as schizophrenia. A number of controversial issues are critically explored, including whether a discrete 'cannabis psychosis' exists, and whether cannabis can actually cause schizophrenia. Effects of cannabis on mood, notably depression, are reviewed, as are its effects on cognition. This book will be of interest to all members of the mental health team, as well as to neuroscientists and those involved in drug and alcohol research.
