PCP

Phencyclidine (a complex clip of the chemical name 1-(1-phenylcyclohexyl)piperidine), commonly initialized as PCP and known colloquially as Angel Dust and by many other names, is a dissociative drug. PCP was brought to market in the 1950s as an anesthetic pharmaceutical drug but was soon taken off the market in 1965 due to the high prevalence of dissociative hallucinogenic side effects. Likewise ketamine was discovered by Parke Davis researchers as a better tolerated derivative for use as an anesthetic pharmaceutical drug. Since this time a number of synthetic derivatives of PCP have been sold as dissociative drugs for recreational and non-medical use.
