Abstract

The authors surveyed a sample of psychiatrists, psychiatric residents, internists, general practitioners, and psychologists in Los Angeles County to determine the number of patients with adverse LSD reactions seen by these professionals during an 18-month period. Over 2,000 adverse reactions were reported on, and the authors regard this as a conservative estimate. Although many clinicians feel that the number of adverse LSD reactions is decreasing, the data reported here indicate a substantial increase from the first six-month period to the third.
