Extreme Hyperthermia After LSD Ingestion
JAMA September 13, 1971 Steven A. Friedman 37 citations
A patient developed life-threatening hyperthermia (106.4 °F or 41.3 °C axillary) after taking LSD, the first recorded instance of such severity in humans. The hyperthermia was rapidly reversed with alcoholic-ice soaks. Hallucinations ended about 18 hours later, and the patient recovered without obvious mental or physical injury. The episode may have been dose-related.
