Or perhaps people predisposed to schizophrenia are more likely to seek out drugs. Something like 9 in 10 schizophrenics smoke cigarettes too, is schizophrenia caused by nicotine or do schizophrenics smoke because they’re predisposed to do so? I find it hard to believe that so many schizophrenics smoke cigarettes and are not also predisposed towards using other drugs.

I think blindly accepting the statement ‘drugs can cause schizophrenia’ is harmful because we don’t actually know if the drugs trigger it or if the disorder makes them seek out drugs.
