Legalize Medical Marijuana. In order for this to happen, Marijuana would have to be reclassified by the DEA (Drug Enforcement Administration) from a Schedule I (controlled substance, no medical use) drug to a Schedule II (for medical use but have a high risk of abuse) drug. The DEA recently confirmed they won’t be doing that anytime in 2016. States still have the power to allow marijuana for medical and recreational use on a state by state basis.
