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: The Unbiased Truth 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. Whether you’re a parent concerned about your child’s use, someone with an illness considering medical marijuana as a treatment option, a user who has questions about its effect on your health, or if you’re just trying to make up your mind about legalization, this book will give you the most current and unbiased information you need to make informed decisions about marijuana.
