PCP

Probably the most over dramatized drug in history next to marijuana. It's extremely rare for a PCP user to become violent and harm other people and those that do were probably crazy to begin with (PCP will lower you inhibitions). In fact if you smoke enough you won't even be able to move. Good luck attacking someone when you can't even move or feel your body. That being said you should probably stay away from it as its VERY unhealthy for your body and brain and the stuff you buy on the street has all kinds of nasty chemicals in it that are worse for you then PCP. Many people who try PCP never try it again because of how "intense", "uncomfortable", and how much of a "mind fuck" it is. There are some people who manage to become psychologically addicted to it and after a smoking it regularly for a while start to lose it and go into their own little world. It's not good for your mental health the same way doing to much acid isn't only in a different way.
