The State of Michigan outlawed smoking in restaurants and bars as of May 1, 2010. The law exempts only cigar bars, retail tobacco stores, private home offices, company vehicles including commercial trucks, and Detroit's three casinos' gambling floors.

How it was before the ban

The following bars, or in some cases restaurants with a liquor license and a reasonable atmosphere for just stopping in for a drink, have a no smoking policy.
