Phencyclidine (PCP) is a potent hallucinogenic drug that is often used recreationally. It can cause a range of effects， including hallucinations， disorientation， and changes in mood and behavior. PCP can also trigger feelings of detachment， but it can also lead to aggression and other extreme behavior changes. These effects can be very dangerous and even life-threatening， especially when combined with other drugs or alcohol. PCP can also cause seizures and coma in some cases. It is important to be aware of the potential dangers of PCP and to avoid using it， especially if you are not experienced with hallucinogenic drugs.
