After ingesting street drugs sold as "PCP," "THC," and "methadone,"
three young men developed schizophreniform psychoses, analgesia,
anesthesia, and amnesia for the psychotic state. Except for their unusually
long duration of 2 to 4 weeks, these reactions resembled phencyclidine
psychoses. The authors are aware of other phencyclidine- related hospital
admissions but could find no information on phencyclidine in recently
published handbooks on drug abuse.
