Marijuana is the most commonly used psychotropic drug in the United States, after alcohol. With the legalization and decriminalization of cannabis, momentum continues to build and propelled by the reduction of stigma associated to its consumption, there is growing concern regarding the long-term impact on brain function and behavior. Cannabis and the Developing Brain aims to provide comprehensive research on the effects of cannabis during neurodevelopment stages (i.e., perinatal and adolescent ages). This book introduces readers to vivo neural circuits, molecular and cellular mechanisms affected by cannabis exposure during three different temporal windows of brain vulnerability. Second, it offers a unique insight to shared neurobiological features of cannabinoid exposure during different developmental periods. Lastly, Cannabis and the Developing Brain determines the adverse impact of developmental cannabinoid exposure on specific cognition, emotion and behaviors. Reviews exposure effects on different areas and circuits of the brain Identifies effects of exposure at prenatal, perinatal, infant, and adolescent ages Includes cannabis interaction with known genetic and environmental risk factors Contains neurodevelopment and neuropsychiatric disorders associated with cannabis exposure

Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.

The trend toward liberalizing medical and recreational marijuana use is increasing the obligation on clinicians to provide useful information to the public. This book summarizes the science all healthcare professionals need to know in order to provide objective and relevant information to a variety of patients, from recreational and medicinal users to those who use regularly, and to adolescents and worried parents. The author brings two and a half decades of studying cannabinoid research, and over forty years' experience in psychiatric and addiction medicine practice, to shed light on the interaction between marijuana and the brain. Topics range from how marijuana produces pleasurable sensations, relaxation and novelty (the 'high'), to emerging medical uses, effects of regular use, addiction, and policy. Principles of motivational interviewing are outlined to help clinicians engage patients in meaningful, non-judgmental conversations about their experiences with marijuana. An invaluable guide for physicians, nurses, psychologists, therapists, and counsellors.

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.

Some people suffer from chronic, debilitating disorders for which no conventional treatment brings relief. Can marijuana ease their symptoms? Would it be breaking the law to turn to marijuana as a medication? There are few sources of objective, scientifically sound advice for people in this situation. Most books about marijuana and medicine attempt to promote the views of advocates or opponents. To fill the gap between these extremes, authors Alison Mack and Janet Joy have extracted critical findings from a recent Institute of Medicine study on this important issue, interpreting them for a general audience. Marijuana As Medicine? provides patientsâ€"as well as the people who care for themâ€"with a foundation for making decisions about their own health care. This empowering volume examines several key points, including: Whether marijuana can relieve a variety of symptoms, including pain, muscle spasticity, nausea, and appetite loss. The dangers of smoking marijuana, as well as the effects of its active chemical components on the immune system and on psychological health. The potential use of marijuana-based medications on symptoms of AIDS, cancer, multiple sclerosis, and several other specific disorders, in comparison with existing treatments. Marijuana As Medicine? introduces readers to the active compounds in marijuana. These include the principal ingredient in Marinol, a legal medication. The authors also discuss the prospects for developing other drugs derived from marijuana's active ingredients. In addition to providing an up-to-date review of the science behind the medical marijuana debate, Mack and Joy also answer common questions about the legal status of marijuana, explaining the conflict between state and federal law regarding its medical use. Intended primarily as an aid to patients and caregivers, this book objectively presents critical information so that it can be used to make responsible health care decisions. Marijuana As Medicine? will also be a valuable resource for policymakers, health care providers, patient counselors, medical faculty and studentsâ€"in short, anyone who wants to learn more about this important issue.

The medical use of marijuana is surrounded by a cloud of social, political, and religious controversy, which obscures the facts that should be considered in the debate. This book summarizes what we know about marijuana from evidence-based medicineâ€"the harm it may do and the relief it may bring to patients. The book helps the reader understand not only what science has to say about medical marijuana but also the logic behind the scientific conclusions. Marijuana and Medicine addresses the science base and the therapeutic effects of marijuana use for medical conditions such as glaucoma and multiple sclerosis. It covers marijuana's mechanism of action, acute and chronic effects on health and behavior, potential adverse effects, efficacy of different delivery systems, analysis of the data about marijuana as a gateway drug, and the prospects for developing cannabinoid drugs. The book evaluates how well marijuana meets accepted standards for medicine and considers the conclusions of other blue-ribbon panels. Full of useful facts, this volume will be important to anyone interested in informed debate about the medical use of marijuana: advocates and opponents as well as policymakers, regulators, and health care providers.

In this instant New York Times bestseller, now available in paperback, renowned neurologist Dr. Frances E. Jensen offers a revolutionary look at the brains of teenagers, dispelling myths and “offer[ing] support and a way for parents to understand and relate to their own soon-to-be-adult offspring” (Publishers Weekly). Drawing on her research knowledge and clinical experience, this internationally respected neurologist—and mother of two boys—offers a revolutionary look at the adolescent brain, providing remarkable insights that translate into practical advice for both parents and teenagers. Driven by the assumption that brain growth was almost complete by the time a child began kindergarten, scientists believed for many years that the adolescent brain was essentially an adult one—only with fewer miles on it. Over the past decade, however, neurology and neuropsychology research has shown that the teen years encompass vitally important physiological and neurological stages of brain development. Motivated by her experience of parenting two teenage boys, Dr. Jensen gathers what we’ve discovered about adolescent brain functioning, wiring and capacity and, in this groundbreaking, accessible book, explains how these eye-opening findings not only dispel commonly held myths about the teenage years, but also yield practical suggestions that will help adults and teenagers negotiate the mysterious and magical world of adolescence. With insights drawn from her years as a parent, clinician and researcher, Dr. Jensen explores adolescent brains at work in learning and multitasking, stress and memory, sleep, addiction and decision-making. The Teenage Brain explains why teenagers are not as resilient to the effects of drugs as we previously thought; reveals how multitasking impacts learning ability and concentration; and examines the consequences of emotionally stressful situations on mental health during and beyond adolescence. Rigorous yet accessible, warm yet direct, The Teenage Brain sheds light on the brains—and behaviors—of adolescents and young adults, and analyzes this knowledge to share specific ways in which parents, educators and even the legal system can help them navigate their way more smoothly into adulthood in our ever challenging world.
