PCP – which stands for phencyclidine – it developed in the 1950s to be an intravenous anesthetic drug, but the side effects patients experienced after using the substance led to the discontinuation of its use for medical purposes. However, it has been introduced as an illicit hallucinogen. It is sometimes called angel dust, embalming fluid, or rocket fuel. As a nonmedical, dangerous drug, PCP is found in powdered form, and it is typically smoked, although it can also be mixed with water and injected, drank, or eaten. It is also sometimes found as a pill or gel capsule.
