I just noticed this Tweet from Rep. Barb Byrum.
I am in session….Hoping to vote on a smoking ban….soon.
Here’s a little more info from the Associated Press. Unfortunately, I’m not going to be around tonight, so I won’t know anything until I get home from work.
The Michigan House is preparing for a possible vote on legislation that would ban smoking at most
workplaces in the state including restaurants and bars.A vote on the legislation is likely late Tuesday. But it does not appear a compromise has been reached between the Democrat-led House and Republican-led Senate on a final version of a smoking ban that might become law.
The House is discussing legislation that as introduced would exempt Detroit casinos and tobacco shops from the ban. The Senate hasn’t taken up a smoking ban bill this year but previously backed a ban that did not include any exemptions

As you probably know by now, the House voted 73-31 to approve a ban, but turned back bipartisan attempts to remove all exemptions. The bill exempts existing cigar bars, tobacco shops and Detroit’s 3 casinos.
No word on what the Senate will do. No agreement has been reached between the chambers.
