Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Ronald Keith
Siegel (b. 1943) is an American psychiatrist, research professor in the
Department of Psychiatry and Biobehavioral Sciences at the University of
California, Los Angeles (as recently as 2005), and the author of several
noted studies and books on psychopharmacology, hallucination, and
paranoia. Siegel has studied, lectured, and conducted research at
Brandeis University, Harvard Medical School, Dalhousie University, and
the Albert Einstein College of Medicine, and has been a consultant to
several government commissions on drug use. His research has focused on
the effects of drugs on human behavior, and has included numerous
clinical studies in which human volunteers (sometimes referred to by
Siegel as "psychonauts") have taken drugs such as ketamine, LSD,
marijuana, mescaline, psilocybin, and THC.
