Persons with opioid use disorder (OUD) in the United States are significantly vulnerable to contact with the criminal legal system (CLS). In CLS settings, provision of evidence-based treatment for OUD is variable and often secondary to punitive approaches. Linkage facilitation at every touch point along the CLS Sequential Intercept Model has potential to redirect persons with OUD into recovery-oriented systems of care, increase evidence-based OUD treatment connections, and therefore reduce CLS re-exposure risk. This narrative review explores the state of the science on linkage facilitation across the varied CLS contexts, including general barriers, facilitators, and opportunities for using linkage facilitation for OUD treatment and related services.
