I've seen a few drugs in here mentioned that should not be used. Now I've never done PCP but I do have a very good friend who has, and seen quite a few documentaries that have people who are on it. I'm not really sure where benadryl came into play here, but everybody should stay away from that. Not only does it make you sleep but you can have some very bad hallucinations.
I am not calling bizzz a liar but I think he's really exaggerating about his use with PCP. My friend took ONE hit from a "sherm" and was thrown into a world of anger, hate, and injuries. I will never believe anybody who says "PCP is a safe drug!". The best thing you can do OP is really stay away from it, that's just common sense. You could have a VERY bad reaction to it! Just stay away D:
