Marijuana is currently listed under the Controlled Substances Act as a Schedule 1 drug, meaning that for the purposes of federal law, the drug has “no medical use and a high potential for abuse” and is one of “the most dangerous drugs of all the drug schedules with potentially severe psychological or physical dependence.” Marijuana shares Schedule 1 status with heroin, and it is more strictly regulated than the powerful prescription painkillers that have killed more than 165,000 people since 1999.
