11. PCP
Street names: Phencyclidine, Peace Pills, Hog, Angel Dust
Phencyclidine (PCP) was developed in the 1950s as an anesthetic, but its medical use was discontinued due to the side effects of hallucinations, delirium, and mania. It is believed to be one of the most dangerous illegal substances. Among other things, PCP users feel detached from their surroundings and since PCP causes a temperature rise many of them strip in public. PCP is often used as a dippy – cigarette that is dipped in PCP. In the USA 274.000 people used it in a life time, and 90.000 in 2013.
