Hello bzm.
I've written about this before in a question someone asked about schizophrenia and marijuana use.
The short answer is, if you never wanted to recover from schizophrenia, a good bet for not being able to recover would be to use drugs and alcohol.
I'm on Geodon, and the prescribing label tells you not to drink while you're taking this atypical.
Drinking and doing drugs if you have schizophrenia is "more bad" in every way.
