PCP, a dangerous hallucinogenic, can cause a type of psychosis that can lead to extreme violence and suicide.

PCP is frequently used as an additive or substitute for street drugs marketed as marijuana, LSD, and methamphetamine. People who use it often do so unknowingly.

Anxiety, fear, paranoia, and disorientation are common effects of PCP.

Some other drugs which may be classified as hallucinogens are included on various pages of the Facts section of this Web site.
