>Is cannabis use really causes some psy uneasies or it just correlates? You can know it's correlation based on the inability to ever get ethics board approval to test this properly. You also know the correlation is poor otherwise the conclusion would be not a risk factor but rather 'you will get schizo' No study was linked in OP so I looked for my own. Effects of extended cannabis abstinence on clinical symptoms in cannabis dependent schizophrenia patients versus non-psychiatric controls from 2018 or so. 4. Discussion Contrary to expectations, there was no change in the severity of psychotic symptoms in patients with schizophrenia with sustained cannabis abstinence. PANSS subscales (positive, negative, general and total) remained unchanged over time irrespective of abstinence status. Moreover, there were no significant associations between recent (in the last week) or cumulative (lifetime) cannabis exposure and PANSS severity scores. Together, these findings suggest that 28-days of cannabis abstinence does not significantly alter psychotic symptoms in patients with schizophrenia. So like... no? Not true?
