drug-induced psychosis
a psychotic state resulting from use or abuse of a variety of illicit or therapeutic substances. Well-described drug-induced psychoses may result from excessive or chronic use of amphetamines, cocaine, or other stimulants; cannabis; LSD, PCP (phencyclidine), or other hallucinogens; and other illicit substances. A variety of medications may produce psychotic symptoms, including anticholinergic drugs at therapeutic doses in susceptible individuals. See also substance-induced psychotic disorder.
