Policy Statement 12, Research Highlight 3

Substance abuse treatment can reduce both criminal activity and drug use, particularly when in-prison treatment is coupled with community-based aftercare.

In-prison drug treatment has been associated with positive outcomes, including reduced use of injection drugs, fewer hospital stays for drug and alcohol problems, and decreased recidivism rates. [1]   The most successful outcomes are found for those who participate in both in-prison treatment and postrelease treatment in the community. [2]   Inmates who participate in residential treatment programs while incarcerated have 9 to 18 percent lower recidivism rates and 15 to 35 percent lower drug relapse rates than their counterparts who receive no treatment in prison. [3]   Several studies have examined the effectiveness of therapeutic communities, which isolate prisoners from the general population and provide them with intensive treatment. [4]   One study found that those who completed both an in-prison therapeutic community program and community-based aftercare were significantly less likely to be reincarcerated than other comparison groups: only 25 percent of this cohort was reincarcerated while 64 percent of aftercare drop-outs and 42 percent of untreated prisoners went back to prison within three years of their release.
