Gov. Pat Quinn signed a bill into law today legalizing the use of marijuana for medical purposes in Illinois in a ceremony at the University of Chicago.
Supporters say the four-year trial program is the strictest law of its kind in the nation. Medical cannabis could be used to relieve nausea from cancer treatment, ease stress on people with multiple sclerosis and comfort AIDS patients.
The Democratic governor’s signature adds Illinois to a growing list of 19 other states and the District of Columbia that have made marijuana legal in some form, according to the National Conference of State Legislatures.
