May i ask the age of your brother when the schizophrenia presented?  And then who gave that diagnosis?

When i was studying,  the DSM IV indicated that schizophrenia was already present and that nothing truly caused it to present.

I keep reading new claims that cannabis is triggering or causing schizophrenia, but i cant seem to find any peer reviewed sources saying how that conclusion comes about.

Yeah research points to drugs don’t cause schizophrenia but people with schizophrenia have a tendency to self medicate and most drugs exacerbate the onset symptoms. It is likely those anecdotes were people trying to self medicate at the prodrome psychosis.
