Phencyclidine use among youth: history, epidemiology, and acute and chronic intoxication.
Phencyclidine use appears to be in a growth phase nationally. Factors contributing to the increasing popularity include the user's ability to control the dosage, an understanding of the immediate effects, and its availability. Those most at risk appear to be young Caucasian males. Phencyclidine-related problems are often like tips of icebergs, the underlying causes of which are hidden from public view. The problems often surface in the form of speech difficulties, memory loss, thinking disorders, personality changes, paranoia, severe depression, violence, accidents, suicides and homicides. Of particular concern to law enforcement personnel is the upsurge in phencyclidine-related violent crimes and carrying of weapons by users to protect themselves from their imagined persecutors. The evidence currently available supports the assumption that if there is a solution to the problem of phencyclidine abuse, that solution is prevention. Therefore, medical personnel and others within the helping professions must be alerted to the fact that phencyclidine is not just another drug problem. The findings from users we have already studied strongly suggest that phencyclidine is not an "upper" or a "downer," but perhaps an "insideouter", with longer term implications.
