Specific polysubstance use patterns predict relapse among patients entering opioid use disorder treatment

Abstract Polysubstance use patterns over the 28-days pre OUD treatment were identified. Polysubstance use patterns were differentially related to relapse during treatment. Individuals using cocaine, heroin, opioids, and THC had a higher risk of relapse. High levels of opioid use pre-treatment predicted high risk of relapse. High levels of heroin use pre-treatment predicted high risk of relapse.
