To examine if the observed changes in the associations between POUD and illegal behaviors over time were specific to POUD or indicative of a broader association between presence of any substance use disorder and illegal behaviors, in post-hoc analyses we examined associations between two other selected substance use disorders and illegal behaviors over time. Multivariable logistic regression was used to measure the strength of the associations between alcohol use disorder and illegal behaviors over time, and between cocaine use disorder and illegal behaviors over time. Unadjusted and adjusted models were identical to those examining the strength of associations between POUD and illegal behaviors over time, excepting substance use disorder. To determine if co-morbid POUD was contributing to results, models were also adjusted for POUD status.
