The ‘Encyclopedia of Psychoactive Drugs’ series does a reasonable job of attempting to be non-judgemental about the recreational use of psychoactive substances. This volume, ‘Marijuana: Its Effects on Mind and Body’ takes an in-depth look at the use, abuse, pharmacology, and social impact of marijuana use. It leans considerably more towards a prohibitionist attitude than legalization, but presents a comprehensive and un-offensive look at Marijuana which would be a good addition to many family library or educational program. Recommended for those seeking a non-permissive yet accurate text on marijuana.
