Book Description
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

The Health Effects of Cannabis and Cannabinoids

Book Description
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.

Languages : en
Pages : 257

Book Description
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.

Pages : 238

Book Description
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.

Pages : 216

Book Description
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.

The Teenage Brain

The Teenage Brain PDF Author: Frances E. Jensen
Publisher: Harper Collins
ISBN: 0062067869
Category : Psychology
Languages : en
Pages : 270

Book Description
A New York Times Bestseller Renowned neurologist Dr. Frances E. Jensen offers a revolutionary look at the brains of teenagers, dispelling myths and offering practical advice for teens, parents and teachers. Dr. Frances E. Jensen is chair of the department of neurology in the Perelman School of Medicine at the University of Pennsylvania. As a mother, teacher, researcher, clinician, and frequent lecturer to parents and teens, she is in a unique position to explain to readers the workings of the teen brain. In The Teenage Brain, Dr. Jensen brings to readers the astonishing findings that previously remained buried in academic journals. The root myth scientists believed for years was that the adolescent brain was essentially an adult one, only with fewer miles on it. Over the last decade, however, the scientific community has learned that the teen years encompass vitally important stages of brain development. Samples of some of the most recent findings include: Teens are better learners than adults because their brain cells more readily "build" memories. But this heightened adaptability can be hijacked by addiction, and the adolescent brain can become addicted more strongly and for a longer duration than the adult brain. Studies show that girls' brains are a full two years more mature than boys' brains in the mid-teens, possibly explaining differences seen in the classroom and in social behavior. Adolescents may not be as resilient to the effects of drugs as we thought. Recent experimental and human studies show that the occasional use of marijuana, for instance, can cause lingering memory problems even days after smoking, and that long-term use of pot impacts later adulthood IQ. Multi-tasking causes divided attention and has been shown to reduce learning ability in the teenage brain. Multi-tasking also has some addictive qualities, which may result in habitual short attention in teenagers. Emotionally stressful situations may impact the adolescent more than it would affect the adult: stress can have permanent effects on mental health and can to lead to higher risk of developing neuropsychiatric disorders such as depression. Dr. Jensen gathers what we’ve discovered about adolescent brain function, wiring, and capacity and explains the science in the contexts of everyday learning and multitasking, stress and memory, sleep, addiction, and decision-making. In this groundbreaking yet accessible book, these findings also yield practical suggestions that will help adults and teenagers negotiate the mysterious world of adolescent development.

Cannabis

Cannabis PDF Author: Marco Colizzi
Publisher: MDPI
ISBN: 3039439952
Category : Science
Languages : en
Pages : 204

Book Description
Over the years, there has been increasing interest into the public health impact of cannabis use, especially by young adults. This follows the evidence of a growing prevalence of regular cannabis use worldwide, with approximately 200 million users. Recreational cannabis use, especially a frequent use of products with high levels of its main psychoactive ingredient delta-9-tetrahydrocannabinol (Δ 9-THC), can cause dependence and have transient and long-lasting detrimental mental health effects, also negatively impacting cognitive processing and brain function and metabolism. In regular users, the development of tolerance to some of the effects of cannabis, especially the pleasurable ones, may lead to progressively heavier use in order to obtain the same effects in terms of their intensity, with higher health risks. However, the Cannabis Sativa plant contains different chemicals with different potential effects. In this regard, cannabidiol has gained interest because of its potential therapeutic properties, in line with evidence that CBD and Δ9-THC may exhibit opposite effects at the cannabinoid receptor type 1 (CB1), Δ9-THC being a partial agonist and CBD an antagonist/inverse agonist. Different cannabinoids may modulate human brain function and behavior in different ways, with different risk–benefit profiles.

Publisher: Academic Press
ISBN: 0128051833
Category : Medical
Languages : en
Pages : 364

Book Description
The Complex Connection 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
