After alcohol and nicotine, marijuana is the most commonly used "recreational" drug in Western countries. There has already been a growing debate about the medical applications of marijuana and other cannabis-based preparations and increasing pressure to legalize such use; voters in several States in the US in the 1996 and 1998 elections approved prosals to implement such measures. In The Science of Marijuana the author explains the remarkable advances that have been made in scientific research on cannabis with the discovery of specific receptors and the existence of naturally occurring cannabis-like substances in the brain. The book also gives an objective and up to date assessment of the scientific basis for the medical use of cannabis and what risks this may entail. The recreational use of the drug and how it affects users is described along with some predictions about how attitudes to cannabis use may change in the future. Leslie Iversen is a scientist who has worked both in academia and in the pharmaceutical industry and has specialized in the study of drug actions on the brain. The book is written with a minimum of scientific jargon or technical language for readers who want to know more about the science that underlies the current cannabis debate.
