Well..PCP is considered kind of dangerous as it can put you into a sort of dream-like reality in which you may think you're living in some sort of fake reality. I personally think meth addicts are more dangerous..saw a census a few years back comparing inmates in prisons across America and about 60% of inmates were in possession or under the influence of methamphetamines while they performed their crime..; but then again I've seen quite a few people that can handle the shit and be perfectly fine. It all depends on the individual person's chemical make-up in the body, personality, and other emotional factors.
