Abstract
Legalization of medical Cannabis has been one of the most controversial areas of state policy change over the past twenty years. However, little is known about whether medical Cannabis is being used clinically to any significant degree. Using data on all prescriptions filled by Medicare Part D enrollees from 2010 to 2013, we found that the use of prescription drugs for which Cannabis could serve as a clinical alternative fell significantly, once a medical Cannabis law was implemented. National overall reductions in Medicare program and enrollee spending when states implemented medical Cannabis laws were estimated to be $165.2 million per year in 2013. The availability of medical Cannabis has a significant effect on prescribing patterns and spending in Medicare Part D.
