A new study from the State Department of Community Health shows Michigan's smoking ban hasn't hurt any restaurants and bars.
The ban went into effect in May of 2010, and some restaurants feared they would lose a good chunk of money. That study shows that overall, the ban hasn't had much of an effect on business.
Some places have lost customers, others have gained business, and others have stayed the same. The Michigan Restaurant Association agrees, and notes that one-third of its members already had their own smoking bans in place before the state-wide law kicked in.
