Illinois Governor Bruce Rauner on Friday signed Senate Bill 2228 which in effect de-criminalizes cannabis.
The bill specifically makes cannabis possession of 10 grams or less, punishable by fines but not jail time.
The bill takes effect immediately.
According to the Marijuana Policy Project, previously in Illinois, possession of up to 2-point-5 grams of marijuana was a class C misdemeanor punishable by up to 30 days in jail and/or a fine of up to 15-hundred dollars.
Possession of 2-point-5 to 10 grams was a class B misdemeanor punishable by up to six months in jail and/or a fine of up to 15-hundred dollars. More than 100 Illinois communities had already removed local criminal penalties for simple marijuana possession.
Illinois is now the 21st state in the nation, in addition to the District of Columbia, to remove the threat of jail time for simple marijuana possession.
