The drug Phencycliding is also known as PCP, peace pill, angel dust, crystal, hog, horse tranquilizer, tic and zoot. It was originally developed as an anesthetic for animals, but has been abused by people looking for an artificial euphoria, with no regard to its harmful effects.

PCP is unpredictable. It gives users various sensations including dissociation from the envrionment, euphoria, hallucinations, relaxation, distorted time, space and body sensations, feelings of floating and weightlessness, inability to think or concentrate, anxiety, paranoia, and other various auditory and visual experiences

PCP depresses and stimulates the central nervous system. It alters speech, coordination, dexterity and vision. It induces dizziness and drowsiness. PCP increases the heart rate, blood pressure, breathing rate, and urinary output. It can induce sweating and vomiting. It causes jerky eye movement that can last for several months, even after one dose.

PCP is often sold as a substitute for other drugs, causing panic in unsuspecting users.

PCP can and often does hurt its users. It causes a loss of sense of pain, psychic experiences, states of panic and fear of death lasting for several days. Bizarre, compulsive and violent behavior, involuntary eye movement, rigin muscles, loss of gag and corneal reflexes. Arching of the body, coma, alternating high and low blood pressure, irregular breathing, severe nausea and vomiting. Loss of memory and though processes, ongoing speech problems, depression, toxic psychosis as aggressive and assaultive behavior, hallucinations.

Death from stopped breating, convulsions, brain hemorrhage, kidney failure, drug combinations, fatal accidents. Murder suicide, self-mutilation and drowning from swimming under the influence to enhance floating sensation. These are things that actually happen to users of PCP. Dependence on PCP arises as tolerance develops. Use is often in "runs" of two or three days, with disorientation and depression after withdrawal.
