From Chicago Tribune:
Getting caught with small amounts of marijuana will result in citations akin to a traffic ticket instead of the possibility of jail time under legislation Republican Gov. Bruce Rauner signed into law Friday.
Rauner’s approval of the decriminalization measure comes after he used his amendatory veto powers last year to rewrite legislation he argued would have allowed people to carry too much pot and fine violators too little.
Supporters incorporated his proposed changes, and under the new law those caught with up to 10 grams of marijuana will face fines ranging between $100 and $200. Individual municipalities could add to the fines and implement other penalties, such as requiring offenders to attend drug treatment. Citations would be automatically expunged twice a year, on Jan. 1 and July 1.
Under previous Illinois law, possession of up to 10 grams of pot was a class B misdemeanor that could result in up to six months in jail and fines of up to $1,500.
