Understanding Marijuana

Marijuana is the world's most popular illicit drug, with hundreds of millions of regular users worldwide. One in three Americans has smoked pot at least once. The Drug Enforcement Agency estimates that Americans smoke five million pounds of marijuana each year. And yet marijuana remains largely misunderstood by both its advocates and its detractors. To some, marijuana is an insidious "stepping-stone" drug, enticing the inexperienced and paving the way to the inevitable abuse of harder drugs. To others, medical marijuana is an organic means of easing the discomfort or stimulating the appetite of the gravely ill. Others still view marijuana, like alcohol, as a largely harmless indulgence, dangerous only when used immoderately. All sides of the debate have appropriated the scientific evidence on marijuana to satisfy their claims. What then are we to make of these conflicting portrayals of a drug with historical origins dating back to 8,000 B.C.? Understanding Marijuana examines the biological, psychological, and societal impact of this controversial substance. What are the effects, for mind and body, of long-term use? Are smokers of marijuana more likely than non-users to abuse cocaine and heroine? What effect has the increasing potency of marijuana in recent years had on users and on use? Does our current legal policy toward marijuana make sense? Earleywine separates science from opinion to show how marijuana defies easy dichotomies. Tracing the medical and political debates surrounding marijuana in a balanced, objective fashion, this book will be the definitive primer on our most controversial and widely used illicit substance.

The leading clinical expert on marijuana sifts through the myths about the drug to deliver an unbiased, comprehensive guide backed by scientific facts to give you the information you need to make informed decisions about marijuana. Marijuana--or weed, pot, grass, MJ, Mary Jane, reefer, cannabis, or hemp among dozens of other names--has a long, colorful history dating back more than 2,000 years as the one of the most sought-after mood-altering substances in the world. Societal opinion about the drug has dramatically swayed over the years, from viewing it as a grave danger to society in the 1930s film Reefer Madness, to a harmless recreational high in the ’60s, to an addictive substance and gateway to such “hard” drugs as heroin today. The myths and misinformation about marijuana have only multiplied over the years as the controversy over legalization and medical marijuana grows.A nationally recognized clinical expert and leading researcher on marijuana, Kevin P. Hill provides a comprehensive guide to understanding the drug in Marijuana: Cutting through the Myths about the World’s Most Popular Weed. Through research-based historical, scientific, and medical information, Hill will help you sort through what you hear on the streets and in the media and cut straight to the facts.

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.

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.

Handbook of Cannabis and Related Pathologies: Biology, Pharmacology, Diagnosis, and Treatment is the first book to take an interdisciplinary approach to the understanding of cannabis use and misuse. Recent worldwide trends toward decriminalizing marijuana for medical use have increased legal use of the drug and recreational use remains high, making cannabis one of the most commonly used drugs.

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.
