Racism, not race: Quantitative analysis of the use of race and racism in the addiction literature

Rationale: Prior research has demonstrated that medical journals rarely mention racism, potentially contributing to an incorrect understanding of and inappropriate interventions for health inequities affecting Black and Brown communities in the US. While this infrequency of mentions of racism has been documented in the general medical literature, it is unknown if this pattern extends to the addiction literature, where some have argued that structural racism has played a specific role in shaping policy and treatment. Objective: To assess how frequently the addiction literature for the last 30 years has mentioned race and racism and if these rates vary with social movements. Methods: We created an algorithm to download and process over 30,000 published articles published from 1990 to 2022 in five major addiction journals: Addiction, Addictive Behaviors, Drug and Alcohol Dependence, Journal of Substance Abuse and Treatment, and International Journal of Drug Policy. Using this data, we reported temporal patterns of mentioning both race and racism across journals and article types. Further, we utilized interrupted time series analysis to identify if the social movements against police violence and the murder of George Floyd in 2020 were associated with significant changes in rates of mentioning racism. Results: While over 30% of the articles in addiction medicine journals included the word race, only 1.5% of articles mentioned racism. Based on an interrupted time series model, after the racial reckoning following the murder of George Floyd in 2020, mentions of racism increased in the addiction literature (OR = 3.21, 95% CI: [2.39, 4.32], P<.001). Conclusions: A large chasm remains between how often authors mention race versus racism in addiction medicine, a field with a unique history intertwined with structural racism. Addressing inequities in addiction outcomes, including burgeoning inequities in overdose deaths, will require acknowledging racism in the scientific literature.
