  • Participants with cannabis use disorder consistently showed increased psychotic disorder prevalence in both surveys, with no change in the strength of this association over time.

Finally got around to reading this 2021 paper on cannabis use & psychotic disorders. Take homes: 1) US psychotic d/o prevalence increased between 2001 and 2013, 2) prevalence was 1.2-2.7 times greater w/ cannabis use. More cannabis=more psychosis https://t.co/U6PyidM6gH https://t.co/6zBWBQg7UA
