PCP is quite a volitile drug. I'll admit I've taken it before, and it removes all sense of pain and pretty much destroys your ego, making someone unpredictable and violent. I wouldn't fight him, even if you are confident. Example- if you're on PCP and punch a cement wall as hard as you can, you're not going to feel it at all and will probably continue to punch the cement wall despite your hands become shattered or badly broken. Don't fight him, as most likely he won't stop trying to attack you until you're dead (even if you beat him to a bloody pulp, he's not going to stop attacking).. and if worst comes to worst, he'll start trying to attack you with any weapon available at the time. My advice: Never ever fight anyone on PCP.
