Do medical marijuana laws reduce addictions and deaths related to pain killers?
Recent work finds that medical marijuana laws reduce the daily doses filled for opioid analgesics among Medicare Part-D and Medicaid enrollees, as well as population-wide opioid overdose deaths. We replicate the result for opioid overdose deaths and explore the potential mechanism. These findings suggest that broader access to medical marijuana facilitates substitution of marijuana for powerful and addictive opioids.
