Wikipedia
Phencyclidine

Phencyclidine (PCP), also known as angel dust and Sernyl among others, is a dissociative drug. PCP was brought to market in the 1950s as an anesthetic pharmaceutical drug but was taken off the market in 1965 due to the high prevalence of dissociative hallucinogenic side effects. Moreover, the discovery of ketamine by Parke-Davis researchers was thought to represent a better-tolerated alternative for use as an anesthetic medication. Since this time a number of synthetic derivatives of PCP have been sold as dissociative drugs for recreational and non-medical use.

In chemical structure, PCP is a member of the arylcyclohexylamine class, and, in pharmacology, it is a member of the family of dissociative anesthetics. PCP works primarily as an NMDA receptor antagonist, where it blocks the activity of the NMDA receptor. As an addictive drug, PCP is associated with compulsive abuse.

As a recreational drug, PCP may be ingested orally, smoked, insufflated or injected.
