Medical use

Main article: Medical cannabis

In 1978 Robert Randall sued the federal government for arresting him for using cannabis to treat his glaucoma. The judge ruled Randall needed cannabis for medical purposes and required the Food and Drug Administration set up a program to grow cannabis on a farm at the University of Mississippi and to distribute 300 cannabis cigarettes a month to Randall. In 1992 George H. W. Bush discontinued the program after Randall tried to make AIDS patients eligible for the program. Thirteen people were already enrolled and were allowed to continue receiving cannabis cigarettes; today the government still ships cannabis cigarettes to seven people. Irvin Rosenfeld, who became eligible to receive cannabis from the program in 1982 to treat rare bone tumors, urged the George W. Bush administration to reopen the program; however, he was unsuccessful.[69]

So it would seem the the Feds say Marijuana is a schedule 1 narcotic. Which means it has no known medical benefits. And in reality they grow it and distribute it to a very small number of patients for very beneficial reasons. What I would like to see is the Fed’s come clean with their stance and reschedule it to a schedule 2 narcotic. Which means that it does have some medical benefits. That would be honest and open up testing and research in this country that could stand to help millions of people.
