BackgroundPeople with substance use disorders (SUD) who have been involved in the legal system often experience stigma upon reentry into the community after incarceration. Although substance use treatment can sometimes be a source of stigma, it may also reduce stigma by facilitating connections with providers, reducing distress, or helping people feel more integrated in their community. However, research has rarely examined the potential for treatment to reduce stigma.MethodsThis study examined stigma experiences and the degree to which substance use treatment reduced stigma among 24 people with SUDs who were receiving care in an outpatient treatment facility after release from incarceration. Qualitative interviews were conducted and analyzed using a content analysis approach.ResultsParticipants reported negative self-judgements as well as perceiving negative judgments from the community upon reentry. With regard to stigma reduction, themes emerged around substance use treatment repairing strained family relationships and reducing participants’ self-stigma. Aspects of treatment that reportedly reduced stigma included the treatment facility having a nonjudgmental atmosphere, patients trusting the staff, and working with peer navigators who had lived experience of SUD and incarceration.ConclusionsResults from this study suggest that substance use treatment has the potential to decrease the negative impacts of stigma upon release from incarceration, which continues to be a major barrier. Though more research on stigma reduction is needed, we suggest some preliminary considerations for treatment programs and providers.
