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.




Endocannabinoid Regulation of Monoamines in Psychiatric and Neurological Disorders


Book Description

The past decade has seen tremendous growth in the study of cannabinoid receptor signaling in brain. The impact and consequences of cannabinoid modulation of monoaminergic (dopamine, norepinephrine, and serotonin) circuits is becoming more clear. Scientists have shown significant interaction between these two systems in a variety of psychiatric and neurological disorders such as affective disorders, multiple sclerosis, and pain or pain disorders. The overarching goal of Endocannabinoid Regulation of Monoamines in Psychiatric and Neurological Disorders is to provide current information on advances in the field of endocannabinoid signaling and potential therapeutic applications with a particular emphasis on monoaminergic circuits. ​




The Complex Connection between Cannabis and Schizophrenia


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




Marijuana As Medicine?


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. 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.




Cannabis


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.




Marijuana and Madness


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. 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.




Therapeutic Uses of Cannabis


Book Description

At the last Annual Representative Meeting of the British Medical Association a motion was passed that `certain additional cannabinoids should be legalized for wider medicinal use.'' This report supports this landmark statement by reviewing the scientific evidence for the therapeutic use of cannabinoids and sets the agenda for change. It will be welcomed by those who believe that cannabinoids can be used in medical treatment. The report discusses in a clear and readable form the use and adverse effects of the drug for nausea, multiple sclerosis, pain, epilepsy, glaucoma, and asthma.




Cannabinoids and the Brain


Book Description

"Parker describes the discovery of tetrahydocannbinol (THC), the main psychoactive component of cannabis, and the further discovery of cannabinoid receptors in the brain. She explains that the brain produces chemicals similar to THC, which act on the same receptors as THC, and shows that the endocannabinoid system is involved in all aspects of brain functioning. Parker reports that cannabis contains not only the psychoactive compound THC, but also other compounds of potential therapeutic benefit, and that one of them, cannabidiol (CBD), shows promise for the treatment of pain, anxiety, and epilepsy. Parker reviews the evidence on cannabinoids and anxiety, depression, mood, sleep, schizophrenia, learning and memory, addiction, sex, appetite and obesity, chemotherapy-induced nausea, epilepsy, and such neurodegenerative disorders as multiple sclerosis and Alzheimer's Disease. Each chapter also links the scientific evidence to historical and anecdotal reports of the medicinal use of cannabis."--Provided by publisher.
