Marijuana legalization and racial disparities in prison incarceration in Colorado and Washington State: a quasi-experimental study
Objectives
This study examines the impact of recreational marijuana legalization on Black-White disparities in overall prison incarceration and drug-related prison incarceration in Colorado (CO) and Washington State (WA).
Methods
We employ a quasi-experimental research design via a matching approach using the synthetic control method (SCM) as well as the difference-in-differences (DiD) method, using data from the National Corrections Reporting Program (NCRP) and the U.S. Census Bureau’s state population estimates from 2006 to 2018.
Results
Our findings suggest that recreational marijuana legalization in these two legalized states is not associated with sizable and significant decreases in Black-White disparities in overall prison incarceration rates or drug-related prison incarceration rates over the post-legalization period, relative to the nonlegalized states.
Conclusions
Recreational marijuana in CO and WA has had a limited impact on lessening racial inequality in imprisonment.
期刊介绍:
The Journal of Experimental Criminology focuses on high quality experimental and quasi-experimental research in the advancement of criminological theory and/or the development of evidence based crime and justice policy. The journal is also committed to the advancement of the science of systematic reviews and experimental methods in criminology and criminal justice. The journal seeks empirical papers on experimental and quasi-experimental studies, systematic reviews on substantive criminological and criminal justice issues, and methodological papers on experimentation and systematic review. The journal encourages submissions from scholars in the broad array of scientific disciplines that are concerned with criminology as well as crime and justice problems.
