Why substance abuse treatment matters in correctional facilities

Substance use disorder is one of the most common health and public safety challenges connected to incarceration. In jails and prisons, untreated addiction can increase withdrawal risks, disciplinary problems, overdose danger after release, and the likelihood of returning to custody. For that reason, modern correctional systems increasingly treat substance abuse care as part of rehabilitation, not just discipline. In Missouri, that approach is visible in the state's prison system, where treatment is built into institutional programming and community supervision services. The Missouri Department of Corrections says substance use disorder treatment is available to people in custody and on supervision statewide. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services/substance-use))

It is important to note that county jails and state prisons are different systems. Missouri's state-level programs are run through the Missouri Department of Corrections, while local jails may have their own policies, staffing levels, and treatment partnerships. That means access can vary widely depending on where a person is held, how long they are confined, and whether they are in a county jail, a state prison, or on probation or parole.

How Missouri structures treatment inside correctional facilities

Missouri uses a layered model that combines screening, assessment, institutional treatment centers, counseling, drug testing, and reentry planning. According to the Department of Corrections, every resident entering the system receives a substance use screening to help identify treatment needs and guide referrals. The department also uses urinalysis drug screening to monitor substance use and support referrals to appropriate services. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services))

The state's institutional treatment centers provide structured, comprehensive substance use disorder treatment. These programs are designed for incarcerated people and, in some cases, parole or probation violators. Missouri describes the programs as a more therapeutic alternative to traditional incarceration, with an emphasis on accountability, relapse prevention, criminal thinking, life skills, and community reentry planning. ([doc.mo.gov](https://doc.mo.gov/programs/education/therapy-treatment))

Missouri also partners with an outside behavioral health provider, Alpharus Health, to deliver treatment services in correctional institutions. The Department of Corrections says this collaboration supports treatment, counseling, and continuity of care. That continuity matters because recovery does not stop at the prison gate; people leaving custody often need medication support, counseling, housing help, and follow-up care to reduce relapse and overdose risk.

Where treatment is offered in Missouri prisons

As of today, Missouri lists multiple institutional treatment centers across the state. These include facilities in Boonville, Bowling Green, Chillicothe, Farmington, Fordland, Fulton, Maryville, St. Joseph, and Vandalia. The department's treatment-center listings show both men's and women's units, with some facilities offering long-term treatment beds. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services/institutional-treatment-programs))

Long-term substance use disorder treatment, described by the department as 12 months or longer for chronic and progressive addictions, is provided at Ozark Correctional Center, Maryville Treatment Center, Chillicothe Correctional Center, and Women's Eastern Reception, Diagnostic and Correctional Center. Missouri also identifies other treatment locations, including Boonville Treatment Center, Farmington Treatment Center, Fulton Reception Treatment Center, Northeast Treatment Center, Western Reception Regional Treatment Center, and Chillicothe Women's Treatment Center. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services/institutional-treatment-programs))

These programs are not limited to one security level. Missouri says treatment beds are located throughout the state from minimum- to maximum-security institutions. That is significant because it shows the state is trying to make treatment available across different custody settings rather than reserving it for only one type of facility. ([doc.mo.gov](https://doc.mo.gov/programs/education/therapy-treatment))

What the treatment model includes

Missouri's correctional treatment approach is broader than simple counseling. The state describes programming that may include substance use assessment, long-term treatment, short-term treatment, special-needs treatment, toxicology services, relapse prevention, and reentry planning. The Missouri Department of Corrections also notes that some residents who were not originally ordered to treatment may now participate if a clinical assessment shows they are appropriate for services. ([doc.mo.gov](https://doc.mo.gov/programs/education/therapy-treatment))

• Substance use screening at intake
• Drug testing and monitoring during incarceration
• Structured institutional treatment programs
• Behavioral health counseling and relapse prevention
• Reentry planning and continuity of care after release
• Naloxone availability for emergency use and release planning

One especially important detail is naloxone access. Missouri says naloxone is available for emergency use throughout its institutions and is also provided to residents upon release. That is a practical overdose-prevention step, especially because the risk of overdose can rise after a period of abstinence in custody.

How Missouri connects prison treatment to community recovery

Correctional treatment is most effective when it continues after release. Missouri's system includes community-based behavioral health services for people on probation or parole, including Improving Community Treatment Success, or ICTS. The state says ICTS was created to provide comprehensive community-based services for justice-involved people with substance use disorders and, in some cases, co-occurring mental illness. Individuals with opioid use disorder are given priority entry. ([doc.mo.gov](https://doc.mo.gov/icts))

Missouri also works with the Department of Mental Health's Division of Behavioral Health to support continuity of care from institutions to community treatment and recovery support services. That coordination matters because many people leaving jail or prison need a bridge between custody and stable community care. Without that bridge, gains made in treatment can be lost quickly. ([doc.mo.gov](https://doc.mo.gov/programs/education/therapy-treatment))

For women, Missouri notes specialized options such as Alt-Care, an intensive outpatient program for female offenders who need substance use treatment and related support services. The state also identifies female-targeted treatment pathways for women who have completed institutional treatment or are under community supervision. ([dmh.mo.gov](https://dmh.mo.gov/alcohol-drug/criminal-justice/policy))

Why this matters for Missouri communities

Missouri's approach reflects a broader shift in corrections: treating addiction as a behavioral health issue that affects public safety, family stability, and long-term reentry success. The state's own materials describe substance use disorder treatment as part of a multi-tiered strategy that includes prevention, identification, and exclusion of drugs from facilities. Missouri also says it established a new investigations unit in 2024 to help identify and shut down sources of drugs entering prisons. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services/substance-use))

That combination of treatment and enforcement is important. Treatment alone cannot solve the problem if drugs continue to enter facilities, but enforcement alone cannot address the underlying disorder. Missouri's current model tries to do both: reduce supply, identify need early, and provide structured care inside institutions and after release. ([doc.mo.gov](https://doc.mo.gov/divisions/rehabilitative-services/substance-use))

What to watch going forward

As of today, Missouri appears to be continuing to expand and refine its correctional behavioral health system. Recent state materials indicate ongoing attention to self-referral options, medication-assisted treatment, and community reentry supports. Because correctional policy can change with funding, staffing, and public health needs, anyone researching a specific jail or prison should verify current local procedures directly with the facility or the Missouri Department of Corrections. ([doc.mo.gov](https://doc.mo.gov/media-center/newsroom/2025-in-review))

For families, advocates, and people navigating the system, the key takeaway is that Missouri has built a relatively developed framework for substance abuse treatment in correctional settings. It is not perfect, and access may differ by facility and legal status, but the state's current model clearly treats recovery as part of corrections policy rather than an afterthought.
