2. Psychosis
One of the most dangerous effects of PCP is psychosis i.e. detachment from reality, and in certain cases the behaviors of such individuals are indistinguishable from those of schizophrenics. In addition, it might even cause paranoia, a feeling of trepidation and anxiety. Isolation from the surroundings can instigate violent, irrational and completely unpredictable behavior, which is why the person is a danger to others around him/her.
