Multiple drug abuse involving nonopiate, nonalcoholic substances. II. Physical damage, long-term psychological effects and treatment approaches and success.

Abstract

A review of the literature of multiple drug abuse involving two or more drug categories where at least one is a nonopiate, nonalcoholic substance (MDA NONA) suggested the possibility that sedative-hypnotics were the culpable agent for neuropsychological deficits in this group. Individually, amphetamines and hallucinogens, primarily LSD, have been associated with long-term psychological disturbance. While many abusers of these drugs who develop psychoses have been documented to be emotionally disturbed prior to drug usage, indicating that the drug exacerbated a prepsychotic condition, other abusers have no such history, indicating a drug-induced psychosis. Current treatment approaches appear to be ineffective for MDA-NONA abusers, as indicated by poor retention rates and relapse to drug use.
