A survey of psychiatrists, psychiatric residents, internists, general practitioners, and psychologists in Los Angeles County counted over 2,000 patients with adverse LSD reactions seen during an 18-month period, which the authors consider a conservative estimate. Despite many clinicians' belief that such reactions were declining, the data show a substantial increase in reported cases from the first six-month period to the third.
