Phencyclidine
PCP (phencyclidine) was first manufactured in the fifties as an intravenous anesthetic. Its use in humans was discontinued in 1965 because patients often became agitated, delusional and irrational while recovering from its anesthetic effects. The PCP is illegally manufactured in labs and sold on the street names as ”angel dust”, “ozone”, “wack” and “rocket fuel”. When combined with marijuana, is known by the names of dead and superyerba glass joints (“killer joints” and “crystal supergrass” in English). The variety of street names for PCP reflects its bizarre and volatile effects.
PCP is a “dissociative drug,” which means that distorts perceptions of sight and hearing impairments producing a feeling of being separated or “disassociated” from the environment and oneself. The dissociative drugs act by altering distribution of the neurotransmitter glutamate in the brain. The glutamate is involved in pain perception, responses to the environment and memory.PCP is a white crystalline powder that dissolves easily in water or alcohol. It has a distinctive bitter chemical taste. It can be mixed easily with dyes and is in the illicit drug market in a variety of forms such as tablets, capsules and colored powders. Usually abused in one of three ways: snorted, smoked or swallowed. For smoking, PCP is often applied to leaves of plants such as mint, parsley, oregano, or marijuana.
