Can marijuana cause paranoid schizophrenia?

Potentially: If you have family history of thought disorders, such as schizophrenia, schizoaffective disorder, or bipolar i disorder with psychotic features, you are at a higher risk than the general population to develop psychosis after smoking marijuana, which may not resolve when you stop smoking. Be careful please.

If predisposed.: I agree with dr. Chenoweth. Possible effects of marijuana include anxiety, depression, fear, panic , delusions, hallucinations, losing touch with reality, inattentiveness, short-term memory problems, & disturbances of thought processes. In individuals with predispostions for major mental disorders - it may trigger disease expression.
