The Montana Cannabis Industry Association filed legal papers with the secretary of state’s office Thursday to start a signature-gathering effort to let Montanans vote in 2012 on a soon-to-be medical marijuana law it opposes. The paperwork was delivered to Secretary of State Linda McCulloch’s office late Thursday. "We’re moving forward on all fronts," said Kate Cholewa, spokeswoman for the group. "The people want what they voted for and what the Legislature did is not it."
