Multiple studies have been done on this topic. Everything indicates that cannabis can function as a catalyst for psychosis in people with a predisposition for develloping such mental disorders, so that people get the psychosis at an earlier stage in life. It has never been proven that 'normal' people also have an increased chance of becoming psychotic.
Didn't you mean schizophrenia?
Anyone can have a psychosis given enough mental stress. (Which basically should make it obvious that cannabis
can be a catalyst although rarely).
