In Psychedelics, Peter Stafford offers a framework for understanding the enormous amount of information available on psychoactive substances. In addition to the photographs, illustrations, charts, and tables, he writes about the origins, varieties, physical and mental effects, societal benefits, complications, and drawbacks of psychedelics, particularly LSD, the most potent and representative of this class of drugs. Stafford also summarizes the promising studies that were halted in the 1960s, along with developments since that time, and offers a fascinating exploration of these drugs.
