      Among over 23k individuals, cannabis use in adolescence was associated with an increased risk of developing depression (OR =1.37), exhibiting suicidal ideation (OR= 1.5), and attempting suicide (OR= 3.46) in young adulthood. https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2723657?guestAccessKey=ce5d508f-1782-42fc-9c88-3df4f499c613&utm_source=silverchair&utm_medium=email&utm_campaign=article_alert-jamanetwork&utm_content=weekly_highlights&utm_term=042719&utm_source=twitter&utm_medium=social&hootPostID=946582fb907865abbf7e31d0795a3c09 …pic.twitter.com/dMkeyeKODH

      Correlation ain't causation.

          Totally agree, but they controlled for baseline depression, which increases my confidence in the findings. However, if future research showed significant genetic overlap between depression and marijuana use, I would not be surprised.

          I think there is evidence of a group with added (genetic) risk for developing schizophrenia, where pot use increases the odds. Question is always, what is causal? There may be a limited time opportunity to test such things by state with an instrumental variable.

          It would be really interesting to see whether similar detrimental effects (to the extent they are real) emerge among adults who use cannabis. I wonder if the harmful consequences have to do with a brain that is still developing.

          Whereas causal inference does permit connections to be based on the conditions of the occurrence of an effect.

          But the distinction needs to then be made regarding “inference of association” which many using casual inference as justification can confuse.
