Correct, except not just temporary if you are genetically predisposed to psychotic disorders. As I recall there was also some research that suggested early onset cannabis use was causally related to psychotic disorders regardless of genetic propensity for psychotic disorders.

Currently on mobile and cruising for sources is a drag; I will do my best to remember to cite some when I get home.

Anecdotally, I’ve known at least three people who have experienced cannabis induced psychosis. All three had a first or second degree family member with a diagnosed psychotic disorder, were males who began cannabis use in their early-mid teens, and had ACE scores of 4+. While this is not the mean cannabis user, it’s surely cause for concern.
