<br/><br/> This paper studies the impact of legal medical marijuana markets on the decision to quit marijuana use, distinguishing between de jure legalization, in which dispensaries are legally protected, and de facto legalization, where dispensaries operate in the absence of laws protecting them. Geographic and temporal variation in the presence of de facto and de jure legalized markets serve to identify their impact on quitting. Although we find little robust evidence that quitting by females is impacted by either the presence or protection of retail medical marijuana dispensaries, our results reveal significant, and ethnically differentiated responses by males. Minority males are found to delay quitting in response to legal protection of dispensaries, while white males delay quitting in response to operating dispensaries. This behavior is consistent with racial and ethnic differences in the risks of arrest for simple marijuana offences, particularly for black males.
