This book is a timely antidote to all of the B.S. that is propagated by those like the last revewer.
Drug addiction "counselors" are the absolute worst, most biased source of information about marijuana you can find. These people deal with drug addicts and other mentally disturbed individuals on a day in - day out basis and have usually lost all contact with reality in regards to the "drug use" of the vast majority of the population in the real world. There is absolutely no harm in smoking a joint now and then (the actual pattern of use by just about everyone who smokes pot in the real world.) Personally, I find the experience quite valuable in finding new ways to appreciate music, art, food, and sex. "Psychologically addictive?" Not NEARLY as much as television. "Physical withdrawal syndrome?" Nope. (The REAL get-your-kids-hooked drug pushers are the [legal and government-subsidized] tobacco companies.) "The 'astronomical' human toll of traffic and industrial accidents?" NOTHING when compared to alcohol. "The economic costs of marijuana's (so-called) amotivational syndrome?" Believe me, television is WAY, WAY, WAY more "amotivating".
Marijuana is the only illicit drug that is used across all social, economic, ethnic, age, occupational, and regional boundaries. It was originally made illegal for racist and political reasons and it is ridiculous that it remains illegal. Get this book, read it, then loan it out to everyone you know.
