Republican Gov. Bruce Rauner on Friday issued an amendatory veto to House Bill 218, which seeks to decriminalize minor marijuana possession offenses.

As initially approved by the legislature in May, HB 218 reduced personal use possession penalties (up to 15 grams) from a Class A criminal misdemeanor, punishable by up to 6 months in jail, a $1,500 fine, and a criminal record, to a petty offense, punishable by a fine only (up to $125.00) – no arrest, and no criminal record. Governor Rauner’s amendatory veto seeks to decrease the proposed possession limits from 15 grams to 10 grams, whole also seeking to raise fines to $200.00.

Governor Rauner also seeks to lower the state’s proposed per se THC/blood limit from 15ng/ml to 5ng/ml. Under present Illinois law, drivers with any detectable amount of THC in their blood are in violation of the state’s traffic safety laws.

If a majority of lawmakers fail to approve of the Governor’s amendments, the measure will be dead for this year’s legislative session.

To date, 20 states and Washington, DC have passed legislation eliminating the threat of incarceration for marijuana possession offenses via either legalization or decriminalization.
