Does Addiction Trigger Genuine Psychosis?
I know that drug use can make people think in a paranoid way.
What I'm wondering is this: There are people who may be prone to developing something like paranoia or schizophrenia; and there are people who may not already be more prone than others.
Can drug abuse trigger or cause a permanent mental illness (the ones above or other psychosis) in people of either group? In other words, can it cause a person who would have otherwise been absolutely mentally healthy to develop psychosis that may then become a permanent problem (without the use of medication)?
What about those who are predisposed to psychosis anyway?
