>> In 1995, 2% of schizophrenia diagnoses in the country were associated with cannabis use disorder. In 2000, it increased to around 4%. Since 2010, that figure increased to 8%, the study found.
Worded that way, causation isn't the first thing this suggests to me. If percentage of cases associated with marijuana rise, it could also be that a larger percentage of the population is smoking and admitting to smoking marijuana regularly. If cases themselves rise, it could also be increases in the percentage of cases that actually get diagnosed, etc.
It could very well be that marijuana puts you at higher risk of schizophrenia - I certainly have an acquaintance in mind for whom recreational drug usage seems to have led them to a paranoid and narcissistic personality described here in other comments - but the connection in this article feels weak. Certainly weaker than the connection we see between marijuana law enforcement and the negative fallout of that.
