A bill that would end the federal prohibition on medical marijuana was introduced in the U.S. Senate last week. On March 10th, Senators Cory Booker (D-NJ), Rand Paul (R-KY) and Kristen Gillibrand (D-NY) presented the Compassionate Access, Research Expansion, and Respect States (CARERS) Act. The measure would reclassify marijuana as a Schedule II substance and thus reduce the government’s ability to regulate the drug, increase research efforts, and allow VA physicians to legally prescribe the drug to veterans. Supporters claims that increasing access to medical marijuana for veterans would improve quality of life for many patients. Additionally, the bill would open new opportunities for medical research concerning marijuana, which traditionally has been one of the most regulated drugs in the field. Since 1999, anyone conducting research on marijuana must also receive a special registration from the DEA, a designation no other Schedule I drug requires for research purposes. The CARERS Act would remove that restriction.
