New perspectives in the legal psychiatry of cocaine-related crimes.

The legal criteria for the insanity defense as it applies to cocaine-related crimes remains elusive because of cocaine's unique spectrum of effects on human thought and action. This paper discusses the literature relevant to cocaine and forensic psychiatry/psychology, and summarizes the results of a survey of forensic psychiatrists on the topic of drug-induced psychosis. A conceptual framework is posited for the expert witness to distinguish the separable effects of cocaine on human behavior and to clarify their relationship to criminal responsibility.
