Smoking in Michigan workplaces, including bars and restaurants, would be banned under legislation passed by the Democratic-led state House.

The vote is a victory for supporters, who have been pushing the measure for a decade.

But it may not get very far in the Senate because majority Republicans oppose it.

Backers say a majority of state residents want a broad workplace smoking ban, and point to the harmful effects of secondhand smoke on employees and patrons.

Opponents say smoking is legal and government shouldn't interfere with the rights of private property owners.

Casinos, horse tracks, bingo halls, cigar bars and smoke shops would be exempt from the smoking ban.
