Sold illicit drugs	2.09 (1.44, 3.05)***	2.41 (1.56, 3.71)***
Stole > $50	1.83 (1.18, 2.84)**	2.12 (1.31, 3.44)**
Attacked with intent to harm	0.99 (0.68, 1.43)	1.03 (0.70, 1.51)

Non-heroin illicit drug use	1.49 (1.06, 2.10)*	1.66 (1.10, 2.52)*

Note: Variables reflect past-year history unless otherwise noted.

Abbreviations: POUD, prescription opioid use disorder; CI, Confidence interval; IOR, interaction odds ratio; AIOR, adjusted interaction odds ratio. Each interaction odds ratio reflects the total 13-year change in the odds for each illegal behavior by POUD status, as measured by the interaction term POUD status*time.

AIORs were adjusted for sex, age and race/ethnicity.
