I swore never to smoke or do drugs in my entire life. NEVER.
Good for you, don't.
when you mean it gets worse, do you mean when your psychosis comes out its much more critical?
People are born with Schizophrenia, and other mental illness. Some aren't. What I mean is, LSD, Shrooms, Marijuana, and other drugs that affect you mentally, can speed up the process at which Schizophrenia can affect you. If you don't have it, don't worry about mental illness then.
But that's the thing, you don't really know if you have schizophrenia or not.
I read somewhere that 4.7% of people who started smoking marijuana at the age of 15, had schizophrenia by the time they were 25. This doesn't mean they developed it, it just means the marijuana increased it's growth, per se'.
