Abstract: The co-occurrence of substance use (SUD) and mental disorders is increasing in the US. Integrating mental health services into SUD treatment facilities improves treatment retention and success, but access to integrated services is lagging behind growing demand. The purpose of this study was to map the locations of SUD treatment facilities that offer integrated mental health services and identify community characteristics associated with whether a treatment facility offers more comprehensive integrated services. We used the Mental health and Addiction Treatment Tracking Repository to identify the location and characteristics of licensed outpatient SUD treatment facilities in the US (2022; N = 8,858). Our focal predictors included the percentage of a census block group that was White, Black, and Hispanic. We used multilevel multiple logistic regression to model whether a facility offered integrated mental health (y/n), adjusted for relevant facility-, county-, and state-level covariates, and defined state as a random effect. The majority of integrated facilities were located in the eastern US, with notable concentrations around large metropolitan areas of Minneapolis, MN, Chicago, IL, Atlanta, GA, and New York, NY. For every 10-percentage point increase in a census block group's Black and Hispanic population, there was a 5% and 7% decrease in the odds of offering integrated services, respectively (aORBlack = 0.95, 95% CI = 0.91–0.99, p = 0.04; aORHispanic = 0.93, 95% CI = 0.90–0.96, p < 0.0001). We frame our findings around social conditions as fundamental drivers of disease and healthcare access and acknowledge the country's historical disinvestment in nonwhite and rural communities. Racially targeted programs are needed to effectively address growing racial and ethnic inequities in SUD and mental healthcare.
