Book Review: Marihuana, Deceptive Weed

This book goes into lots of great detail and it discusses a 5000-year history of cannabis, citing a lot of studies and includes lots of data and charts.  BUT, it doesn't mention "Reefer Madness" and the anti-marijuana propaganda of the United States 1930's and 40's.  In my opinion, most of the research that the book cites in the 60's and 70's need to be taken with a grain of salt.  People who were participating in these studies had been essentially told that marijuana will make you lose your mind and go crazy.  So I believe a lot of them 'acted out' the way they believed it would affect them.
