Violence associated with chronic phencyclidine (PCP) abuse was
investigated by administering a structured interview to 16 chronic PCP
abusers. A more intensive study was done of another individual who
committed murder and self-mutilation under the influence of PCP. The
results suggest that there is no consistent association between PCP-
related violence and a history of violence not related to drug or alcohol
abuse. The author defines four types of violence associated with chronic
PCP abuse.Abstract Teaser
