Government-run pot garden in Mississippi

The Coy W. Waller Laboratory Complex on the campus of the University of Mississippi is where the U.S. government manages the nation's only legal pot garden.

Since 1968 the university has been allowed to grow, harvest, and process marijuana in order to ship it to licensed facilities across the country for research purposes. It also gathers samples of pot confiscated by police to determine its potency and see if a certain strain makes it big on the streets. That way, officers would be better informed on the type of weed people are smoking before locking them up in an overcrowded jail.

The lab has about 500 plants, with an overall weight estimated at 10 to 15 kilos.
