Psychosis is believing something that is neither true, nor socially acceptable. The latter differentiates it from religions that are not yours and political parties that are not yours. Psychosis can be symptomized by hallucinations of visions of things that are not there, sounds of things that are not there, smells of things that are not there, and sensations of things that are not there. The difference between psychosis and drug-induced hallucinations is that drugs are not involved with psychosis, it is your own mind playing some very nasty tricks on you because it wants to be evil and prove how powerful it is. The cure for psychosis is to feed your evil mind drugs that will unscramble its scrambled malfunctioning brain chemistry. Because if your beliefs are not socially acceptable, and cannot be proven, you obviously have a malfunctioning brain which must be made to conform.
