the schools can be customized to meet local needs, such as reducing stigma, which was cited as an important barrier to help-seeking among Hispanics.283 While small, the number of RHSs has been climbing slowly over the past 30 years as shown in the chart, above.284 Like an RHS, an Alternative Peer Group (APG) combines clinical and peer recovery support. APGs adopt a family-centered model, offering a supportive community of recovering peers and a broader positive social environment. They combine these with counseling and case management services.285 APGs differ from RHSs in that they are community- rather than school-based. APGs are also small in number but growing. There were 24 established APGs in 16 states in 2019. At that time, 20 more were in development.286 APGs can become key components of integrated youth service networks, linking with adolescent SUD treatment programs, RHSs, and other youth-serving organizations. While APGs incorporate many practices and elements associated with positive outcomes, effectiveness research is currently lacking. Recovery housing is the most widely available form of recovery support infrastructure in the United States. In 2020, it was estimated that there may be more than 17,500 recovery residences nationally.287 Research on Oxford Houses—rented homes jointly operated by residents who share a lease and other costs—found that residents who stay for six months or more are less likely to return to substance use than those who remain a shorter period of time.288 A study of recovery residences found that residents achieved significant improvements in alcohol and drug use, employment, psychiatric symptoms, and criminal justice system involvement.289 Further, an experiment in which participants with OUD were randomly assigned to usual care, abstinencecontingent recovery housing, or a combination of reinforcement-based treatment and recovery housing found that abstinence-contingent recovery housing was associated with higher rates of abstinence and that the addition of intensive reinforcement-based treatment (RBT) further improved outcomes.290 A subsequent study with a similar population yielded similar results.291 Sustainable financing for PRSS is indispensable. While time-limited discretionary grants have been instrumental in initiating, expanding, or enhancing peer services and RCOs, reliable longterm revenue streams are essential to developing a sustainable RSS infrastructure. The Administration’s call for an expanded Substance Abuse Prevention and Treatment Block Grant (Block Grant) with a 10-percent RSS set-aside, included in the President’s budget, represents an important step in this direction. In addition, Medicaid—can play a role in funding PRSS, including in the context of accountable care organizations, chronic care models, and alternative payment mechanisms focusing on outcomes or values-based purchasing, which can offer flexible options for covering the cost of this service. Medicare may also be able to play a role in reimbursing PRSS. « « « « « « NATIONAL DRUG CONTROL STRATEGY 65 Virtually all of our efforts to address substance use and SUD—from primary prevention and harm reduction, to law enforcement, treatment, and recovery support—are impeded, to a greater or lesser degree, by still pervasive stigma. A phenomenon most acutely experienced by people with SUD and those in recovery, stigma is a cross-cutting concern that requires significant coordinated efforts to address. The stigma associated with substance use manifests in many ways and intersects with a range of factors, including race, gender, and socio-economic status. Social stigma is embodied in negative attitudes and beliefs about substance use and people with SUD and can be reflected in discriminatory policies and practices based on or influenced by those negative attitudes and beliefs. When embodied in policies and practices that limit the opportunities, access to resources, and wellbeing of stigmatized groups, social stigma is sometimes referred to as structural stigma.292 Finally, people with SUD apply the negative attitudes and beliefs reflected in social stigma to themselves, resulting in a phenomenon known as self-stigma. As this occurs individuals may blame themselves for having SUD and/or may believe that their SUD is the result of inherent moral weakness on their part. This leads to shame and fear of social exclusion or other negative results if their condition is exposed. This can result in individuals avoiding treatment or other services.293,294,295 The Administration’s planned activities to address stigma are discussed throughout this chapter. As part of its effort to build back better following the COVID-19 pandemic, the Administration will work to increase our scientific understanding of recovery, foster adoption of more consistent certification and accreditation standards for peer workers and the organizations that employ them nationally, expand the PRSS workforce and the organizational infrastructure that supports it, address stigma and misunderstanding, and eliminate barriers to safe and supportive housing, employment, and education for people in recovery. In all of these efforts, the Administration will continue to solicit input from and build partnerships with the recovery community and
