Ten years ago the original edition of From Chocolate to Morphine was recognized immediately as the definitive guide to legal and illegal drugs. Now best-selling author Dr. Andrew Weil and coauthor Winifred Rosen have revised their popular book, providing essential information about the new drugs of the 1990s.

Drugs remain pervasive, and parents and children alike need complete, unbiased information about how drugs affect the mind and the body. Neither condoning nor condemning drug use, the authors cover a wide range of available substances, from coffee to marijuana, from antihistamines to psychedelics, from steroids to the new "smart drugs." Besides describing the likely effects of each drug, the authors discuss precautions and alternatives, thus allowing readers to make informed and intelligent choices.

Extensively illustrated, supplemented by helpful comments from drug users and nonusers, From Chocolate to Morphine is a unique resource. This clear-headed, authoritative book is now more valuable than ever.
