"Most people with OUD in the United States do not receive any treatment at all, and those who do receive any type of treatment may wait years to do so. Of the small proportion of people who do receive treatment, just a fraction receive medication. Access to evidence-based treatment is poor across the board, but it is starkly inequitable among certain generational, racial, ethnic, social, and economic groups. Although the research is not yet granular enough to develop tailored treatment guidelines for specific subpopulations, the available evidence supports the effectiveness of medication for treating OUD in all groups, including adolescents, pregnant women, and people with comorbidities. However, the treatment gap is exacerbated for vulnerable populations, whose members face steep barriers in accessing medications."
