If you have OCD will smoking marijuana cause schizophrenia if no one in your family has schizophrenia ?

Since OCD is a mental illness can the marijuana make the symptoms of OCD worse and can it also cause schizophrenia? No one in my family had or has schizophrenia but my 2nd and 3rd cousins have OCD.

Experimenting with any drug is dangerous and can cause psychosis sometimes. The only safe thing to do is to not use any drugs, even MJ. Sometimes people lace MJ with other drugs and this may cause fatal results.

Then why are you asking such a silly question? Don't smoke marijuana and you won't have to worry about it, will you?
Marijuana may exacerbate (worsen) the symptoms of mental disorders like OCD. However, there's no definitive proof that it will "cause" a mental disorder (OCD or schizophrenia).

It's not a great idea to do any kind of illicit drugs ever, and that goes double if you have a mental illness or any other kind of medical condition.

Schizophrenia usually occurs in your 20's in college students. Current research show that schizophrenia is correlated with great amounts of stress (college) a farmer moving to town(true story), ect.....

Statistics are extremely high that if you have one mental illness you are likely to have two or three. But I think mental retardation is the primary and schizophrenia and ocds are secondary, if you know what I mean
took classes
no that is a crazy question
