Differences in opioid use and overdose among younger and older justice-impacted adults

Justice-impacted persons aged 40 and up with substance use disorders (SUD) demonstrate increased health risks and health disparities relative to general population peers. Persons with SUD are less likely to age out of criminal behavior, appearing on criminal dockets, in jails, prisons, and under community supervision throughout the life course, with greater community-level cost burdens as they age. Justice system involvement presents health risks that compound with SUD to undermine well-being, which is amplified as people age and experience age-related health decline. Propensity for premature mortality from overdose is startlingly high for this population, highlighting demand for targeted policies to better meet the needs of this vulnerable group. To better understand justice-impacted older adults in treatment for SUD and inform policy, we examined opioid use outcomes among 357 low-income justice-impacted adults in SUD treatment in the Midwest, USA, including a natural oversampling of Black and American Indian or Alaska Native (AIAN) persons. We explored patterns among persons in their 40s, 50s, and 60s, relative to those under 40, conceptualizing life-course risk factors and using logistic regression to assess overdose, opioid use, and opioid agonist medication use.

Significant differences in opioid use by age were observed, with older persons less likely to report opioid prescription misuse or illicit opioid use. Differences were not significant once controlling for user preferences, race/ethnicity, gender, family, childhood, and life course experiences. Overdose history was also significantly less likely for the 40 and older SUD patient, though this was no longer significant when controlling for demographic covariates. Opioid agonist medication use did not significantly differ by age.

Justice-involved patients aged 40 and up in SUD treatment were less likely to have experienced overdose or report opioid use, relative to their younger peers, but this variation dissipated when considering demographic, family and/or life course factors. Targeted treatment services for gender and racial minorities may be beneficial for patients 40 and up. We identify preference for one substance, versus two, as protective against overdose and opioid use among older persons who use drugs.
