Yeah, I've heard stories about bad trips and shit... I don't think you gotta be a violent person to get violent off a PCP overdose... And NO I'm not saying it's an excuse or anything, or it's not his fault, or he shouldn't take responsibility & be punished, I'm just saying that from what I've read it can make you violent...
From some gov. website:
PCP produces impairments and other observable effects on the human mind and body that are a combination of effects produced by depressants, stimulants, and hallucinogens. Blank stare Disorientation Loss of memory Muscle rigidity Non-communicative Sensory distortions Slow, slurred speech Agitation - Excitement Auditory hallucinations Increased pain threshold Loss of a sense of personal identity A feeling of extreme heat, profuse perspiration Passivity - but many users may abruptly turn violent if confronted with a threatening situation
As with many other drugs, regular users of PCP may have developed a tolerance to the drug that masks some of the observable signs of PCP's effects. When smoked or injected, PCP's effects generally last 4-6 hours, but they can last longer. PCP can also enter the body by absorption through the skin.
One possible result of PCP overdose is bizarre, violent and self-destructive behavior. PCP can also produce extreme physical as well as psychological distress. PCP can cause a deep coma, lasting up to 12 hours, seizures and convulsions, respiratory depression, and possible cardiac problems.
