We note several important limitations. We note that suicide rates have changed significantly over the past several decades, partially spanning the interval of data collection. Additional research is needed in the area of suicide attempts among individuals with substance use disorders and other psychiatric comorbidities. While this study focused on AD, there is also a high rate of suicide attempts among individuals with other substance use disorders, particularly cocaine and opioid use disorders. Additionally, we do not have data on those who died by suicide, which may differ from those who have attempted but not taken their own lives. Lastly, larger and more diverse samples are needed so that the benefits of this research can benefit all segments of the population [77].
