Research shows that medications for opioid use disorder — buprenorphine, methadone, and naltrexone — reduce opioid use, prevent overdose deaths, and support long-term recovery. Among people who were formerly incarcerated, access to these medications during incarceration or at release has been shown to reduce overdose deaths, increase use of community-based treatment(link is external), and decrease rates of reincarceration(link is external). However, access to medications for opioid use disorder in jails remains limited due to various barriers, including cost, staffing, and regulatory challenges.
