Medical Marijuana Laws for Patients Map

The U.S. federal government has not endorsed the medical benefits of marijuana, and the Controlled Substances Act of 1970 makes marijuana use illegal on the federal level, classifying it as a Schedule I drug with no currently accepted medical use. Despite the federal ban on medical marijuana, the map below explores the twenty-four jurisdictions that have passed laws explicitly legalizing medical marijuana use for qualified individuals. State medical marijuana laws regulate patient users, caregivers, dispensaries, oversight committees, and health agencies that administer medical marijuana programs. This map focuses on current U.S. laws related specifically to patient use of medical marijuana.   

Some states have passed laws that are favorable to medical marijuana; however, they do not legalize its use, such as Iowa and South Carolina. Other states, such as Pennsylvania, are currently considering pending legislation to legalize its use.
