I know that schizophrenia can be drug induced. A psychoactive drug can cause it. Antipsychotics are psychoactive drugs. So are antidepressants. So it makes sense that these drugs can cause schizophrenia. If I have it it is definitely drug induced. I have never taken cannabis or any other illegal drug so the psychosis must have been brought on by withdrawing from antipsychotics. It's disgusting how psychiatrists can change a diagnosis and say they got it wrong all those years ago rather than admit their drugs caused the problem. That is the power they have I am afraid. They should be in jail.
