Racial Disparities in the Wake of Cannabis Legalization: Documenting Persistence and Change

One of the arguments in support of the legalization of cannabis is that it would help alleviate racial disparities in the criminal justice system. Using UCR data from Colorado and Washington, we explore trends in cannabis arrests disaggregated by rates using interrupted time-series analysis, linear mixed models, and data visualizations. The results demonstrate a general decline in cannabis arrests for nearly all racial groups, yet these declines were not consistent across racial groups or even across states. Moreover, substantial racial disparities persist following legalization, especially in Colorado. Overall, evidence suggests that while legalization has likely had a net positive effect on overrepresented populations by decreasing criminal justice contact, it is not a panacea and may only be minimally important for addressing disparities.
