Researchers find that recreational use of cannabis was significantly associated with a diagnosis of psychotic disorder. Their findings have been published in The American Journal of Psychiatry.
Here’s what they conclude:
“Nonmedical cannabis use and cannabis use disorder were consistently associated with self-reported psychotic disorders over time, while frequent and daily/near-daily use was also associated with self-reported psychotic disorders in the more recent survey. The increasing perception of cannabis as a harmless substance may deter the general public as well as health care providers from recognizing that nonmedical cannabis use may play a role in exacerbating the risk for psychotic disorders.
Therefore, improving public knowledge and educating providers about this risk may serve a useful function. In particular, identifying cannabis use disorder may help indicate individuals at increased risk of psychotic disorders. This information can inform addiction specialists and other clinicians about the need for evaluation and appropriate interventions and therapeutic modalities for individuals at risk.”
