(Chicago, IL) — Voters in Cook County may see a question on the March ballot about legalizing marijuana. But the plan right now is simply for an advisory referendum on whether the state of Illinois should legalize the drug. Cook County Commissioner John Fritchey yesterday said that legalizing marijuana could bring-in between 300 and 700 million-dollars in new money to the state. Cook County President Toni Preckwinkle also support the advisory vote.
