Thirty-four states have adopted medical marijuana laws and ten states have adopted recreational marijuana laws. There is little research comparing how these two types of laws affect drug consumption of the general US population. Using a difference in difference strategy, we find that recreational laws increase past-year marijuana use by 25% among adults and by 10% among adolescents. In contrast, medical laws increase adult use by only 5% and have a negligible effect on adolescent use. We also find that recreational marijuana dispensaries are an important driver of the increase in marijuana use for adults 26 and over. Taken together, our results suggest that medical laws are not de facto recreational laws in that they succeed in mitigating recreational use, that recreational laws have broad effects on overall levels of marijuana use, and that underage marijuana use may be an important problem with existing implementations of recreational marijuana laws.

Medical marijuana laws generate significant debate regarding drug policy. For instance, if marijuana is a complement to hard drugs, then these laws would increase the usage not only of marijuana but also of hard drugs. In this paper I study empirically the effects of medical marijuana laws by analyzing data on drug arrests and treatment admissions. I find that medical marijuana laws increase these proxies for marijuana consumption by around 10–15 percent. However, there is no evidence that cocaine and heroin usage increases. From the arrest data, the estimates indicate a 0–15 percent decrease in possession arrests for cocaine and heroin combined. From the treatment data, the estimates show a 20 percent decrease in admissions for heroin-related treatment, although there is no significant effect for cocaine-related treatment. These results suggest that marijuana may be a substitute for heroin, but it is not strongly correlated with cocaine. © 2015 by The University of Chicago. All rights reserved.

PURPOSE: Several states, particularly in the Southeast, have restrictive medical marijuana laws that permit qualified patients to use specific cannabis products. The majority of these states, however, do not provide avenues for accessing cannabis products such as in-state dispensaries. METHODS: We conducted a survey of patients registered for medical marijuana (low tetrahydrocannabinol [THC] oil cards) in an ambulatory palliative care practice in Georgia (one of the states with restrictive medical marijuana laws). RESULTS: We had a total of 101 responses. Among our sample of patients who use cannabis as part of a state-approved low THC oil program, 56% were male and 64% were older than age 50 years. Advanced cancer was the most common reason (76%) for granting the patients access to a low THC oil card. Although patients reported cannabis products as being extremely helpful for reducing pain, they expressed considerable concerns about the legality issues (64%) and ability to obtain THC (68%). Several respondents were using unapproved formulations of cannabis products. For 48% of the patients, their physician was the source of information regarding marijuana-related products. Furthermore, they believed that their health care providers and family members were supportive of their use of cannabis (62% and 79%, respectively). CONCLUSION: Patients on Georgia’s medical marijuana program are most concerned about the legality of the product and their ability to obtain marijuana-related products. Therefore, we recommend that states with medical marijuana laws should provide safe and reliable access to cannabis products for qualifying patients.
