An estimated 15% of the 1.8 million incarcerated individuals in the US have opioid use disorder (OUD).1,2 These individuals have a substantially higher risk of overdose after leaving correctional facilities.1 Pharmacotherapy for OUD is associated with reductions in postincarceration mortality, yet as of 2018, less than 14% of correctional systems offered buprenorphine or methadone.3 Over the past 5 years, more municipalities and states have enacted policies to provide access to OUD treatment, but the extent to which this implementation has actually increased buprenorphine use remains unclear.
