That the source is a dated Australian Department of Health web page that does not advocate your position. How about primary medical evidence from peer-reviewed medical articles and studies? Moreover, comorbidity refers to a patient having a combination of illnesses. As to alcohol abuse and schizophrenia, the term comorbidity does not provide an inference that alcohol causes or directly worsens schizophrenia. At most, it means that alcohol abuse makes the life of a schizophrenia patient harder and treatment more difficult.
It's from 2007 - "dated" only if there's reason to suppose that more recent evidence weighs against the conclusion that alcohol use may trigger psychosis in people who are vulnerable to developing schizophrenia. Can you offer any reason to so suppose?
Australian Department of Health web page
That was clear from the URL so not omitted.
that does not advocate your position.
I don't know what this claim of yours has to do with allegedly omitted context. Are you saying something else from that source says alcohol is not harmful to mental health?
comorbidity
is not mentioned on the page in question.
alcohol is more addictive than marijuana, more violence-increasing, and the only one of the two that can lead to fatal overdose.
I notice you've declined several opportunities to address these points. Why is that?
