We note several important limitations. First, we focused on lifetime risk for all of the clinical measures included and cannot speak to the time order between these clinical risk factors and suicide attempt. Future research can harness the smaller subset of prospective participants in COGA to examine the longitudinal associations between psychiatric conditions and future suicide attempt among those with an SUD. Second, we focused exclusively on AUD. There is also a high rate of suicide attempts among individuals with other SUDs, particularly cocaine and opioid use disorders. Lastly, we did not have data on those who died by suicide, which may differ from those who have attempted but not taken their own lives.
