Little data exists relative to ongoing treatment of adolescent phencyclidine (PCP) abusers. This paper presents data gathered on a cohort of 87 residents in an adolescent social rehabilitation program. Approximately 50% of this cohort were either chronic or occasional PCP users. Both groups were found to be regular users of other drugs. Demographic characteristics are described, as are behaviors and symptoms reflective of various emotional and behavioral problems. When length of stay of non-PCP users and occasional and chronic users was compared, it was found that chronic users remain in treatment longest. No PCP-induced psychosis was found. Symptoms of depression, anxiety, aggitation, and other reported psychological effects of PCP were seen. Considerations for treatment are briefly discussed.
