A survey released just before Election Day finds that 61 percent of Michigan voters support a statewide medical-marijuana ballot item, with 30 percent opposing the measure, the Detroit Free Press reported Nov. 1.

The Detroit Free Press/Local 4 Michigan Poll questioned 616 "definite" voters on Question 1, which decriminalizes possession of marijuana under state law for medical use with a doctor's authorization.

Voters under age 45 and Democrats were more likely than older voters and Republicans to support the measure; 9 percent said they were undecided.

Some law-enforcement and medical groups oppose the Michigan medical-marijuana item, but only recently organized a "no" campaign.
