A Brief History of Medical Marijuana

from Time

On Oct. 19, the U.S. Justice Department announced that federal prosecutors would not pursue medical-marijuana users and distributors who comply with state laws, formalizing a policy at which the Obama Administration hinted earlier this year.

Currently, 13 states allow doctors to prescribe medical marijuana to patients suffering from ailments ranging from AIDS to glaucoma, and in Maryland a prescription can soften punishment if a user faces prosecution. But until now those laws didn't provide any protection from federal authorities.

Should Professors Cheech and Chong ever receive university tenure teaching the medical history of their favorite subject, the course pack would be surprisingly thick. As early as 2737 B.C., the mystical Emperor Shen Neng of China was prescribing marijuana tea for the treatment of gout, rheumatism, malaria and, oddly enough, poor memory. The drug's popularity as a medicine spread throughout Asia, the Middle East and down the eastern coast of Africa, and certain Hindu sects in India used marijuana for religious purposes and stress relief.
