PCP

AKA Angel Dust

Recreational use
PCP is consumed recreationally, mainly in the United States[citation needed], where the demand is met by illegal production. The drug is sold in an extremely limited number of cities, such as Washington, DC and Los Angeles[citation needed]. It is available as a liquid (PCP base dissolved most often in ether), but typically it is sprayed onto leafy material such as marijuana, mint, oregano, parsley or Ginger Leaves, and smoked. It is sometimes taken with Ecstasy -- a practice known as "Elephant flipping". PCP is a Schedule II substance in the United States and a Class A substance in Great Britain.

Effects
Whether PCP has any strong and consistent effects which are markedly different from other similar compounds is controversial. Some think that the drug's effects are as varied as its appearance. It may be that a moderate amount of PCP will cause users to feel detached, distant, and estranged from their surroundings. Numbness, slurred speech, and loss of coordination may be accompanied by a sense of strength and invulnerability. A blank stare, rapid and involuntary eye movements, diarrhea, and an exaggerated gait are alleged to be among the more observable effects. PCP can sometimes elevate body temperature, which is why many people under the influence of PCP have been known to shed clothing in public places. Acts of violence have been committed by people high on the drug; a well-known example is Brenda Ann Spencer, who claimed to have committed her school massacre while under the influence of alcohol and PCP.

According to the National Institute on Drug Abuse: at high doses of PCP, blood pressure, pulse rate, and respiration drop. This may be accompanied by nausea, vomiting, blurred vision, nystagmus, drooling, loss of balance, and dizziness. High doses of PCP can also cause seizures, coma, and death (though death more often results from accidental injury or suicide during PCP intoxication). High doses can cause symptoms that mimic schizophrenia, such as delusions, hallucinations, paranoia, disordered thinking, a sensation of distance from one’s environment, and catatonia. Speech is often sparse and garbled.
