The intersection of substance use stigma and anti-Black racial stigma: A scoping review

Background

Substance use stigma poses a barrier to treatment and recovery from substance use disorder. Stigma is amplified when intersecting with other stigmatized identities, particularly Black racial identity. Despite increasing attention to the intersecting roles of racial and substance use stigma, it is unknown how these stigmas interact to impact treatment and health outcomes among Black people who use drugs. This scoping review examines empirical research documenting differential impacts of race and racism on substance use stigma.

Methods

We systematically searched PsychInfo and PubMed databases. Eligible studies were conducted in the U.S.; examined a Black sample, subsample, or experimental condition/variable (i.e., in a vignette); and measured substance use stigma (excluding alcohol or nicotine). Qualitative studies describing a theme related to substance use stigma were also included.

Results

Of 1431 unique results, 22 articles met inclusion criteria. The most measured substance use stigma type was interpersonal (e.g., discrimination). Most quantitative findings (n = 15) suggested that Black members of the general public endorse less substance use stigma and Black people who use drugs face less substance use stigma relative to their White counterparts. Qualitative studies (n = 7) suggested stigma was a more common and pernicious substance use treatment barrier for Black people compared to White. Across methods, racial prejudice was associated with substance use stigma, supporting hegemonic ideas that substance use is stereotypically characteristic of Black people.

Conclusions

The interaction between substance use stigma and race is complex and varies by in-group and out-group raters as a function of racial identity and identity as a person who uses drugs. Contradictory findings reflect methodological differences, emphasizing the need for more unified measurement of substance use stigma. More research is needed among Black people who use drugs to improve understanding of the impact of these intersecting stigmas on racial inequities in substance use treatment, morbidity, and mortality.
