EUGENE, Ore. (AP) — The U.S. government considers marijuana among the world's most dangerous drugs, classifying it as a highly-addictive substance that has no medical use.But there's a catch: The government also supplies four people with 300 marijuana cigarettes each month. They are patients in the government's Compassionate Investigational New Drug Program.The program began when a Washington, D.C., man sued the government in order to get access to marijuana to treat his glaucoma. He won, and the program was born.The pot is grown in Mississippi as part of the government's research into marijuana. It's then sent to a facility in North Carolina, where it is rolled into cigarettes.The government distributed more than 100 pounds of high-grade marijuana to patients between 2005 and 2011.
