Cannabis and Schizophrenia

There is no genetic overlap between cannabis use disorder and schizophrenia. But we know that cannabis use can predict levels of schizophrenia, which says that this may be more or rather it goes against the theory that people who are prodromal are just going to smoke more when they're younger. Caspie also found an increased risk of psychosis among adults who use marijuana and adolescents who carry a specific variant of a gene called COMT which degrades things like dopamine in the brain.
