"Marijuana. It's been called a gateway drug, an introduction to the world of harder illegal drugs. Yet many people consider it to be a safe drug--at least safer than heroin, LSD, or cocaine. However, while marijuana might not be directly responsible for causing any deaths, the consequences of its use can be detrimental to the lives of its users. This book describes the history of marijuana use, the dangers of its use, and the legal consequences. You'll also learn about the controversies surrounding the drug--including the issues of decriminalization and the use of medical marijuana. Treatment options for marijuana dependency are also discussed"--The publisher.
