There have even been many instances where PCP users have jumped off the buildings thinking that they could fly. It exaggerated almost everything that was going on for me. You'd be on a crowded bus and you might go into rage without any real reason. Although the production of PCP is illegal in most countries, it is nevertheless easily and widely manufactured. Sometimes it may not even be PCP, but a lethal by-product of the drug.
Users can never be sure exactly what they are buying, so at every use they are risking their lives.
