Characteristics of 68 chronic phencyclidine abusers who sought treatment

An analysis of 68 phencyclidine (PCP) users who sought treatment reveals that chronic compulsive, daily use occurs and that intravenous use is relatively common. Twenty-five (37%) subjects considered themselves to be addicted to PCP and 19 (29%) desired medication to assist withdrawal. Unwanted behaviors under the influence of PCP were common and primarily related to memory loss, or acts which resulted from loss of impulse control.
