LANSING, Mich. (WZZM) - A new study says that, as a whole, Michigan bar and restaurant sales have not been hurt by Michigan's smoke-free air law.

The Michigan Department of Community Health commissioned the University of Michigan Institute for Social Research to conduct the study. The professor who conducted the study used sales tax collection data from the state Department of Treasury and Club Keno sales. Data was evaluated from 2006 to 2011. The law took effect on May 1, 2010.

"It is important to note that while some establishments saw sales fluctuations after the passage of the Dr. Ron Davis Smoke-Free Air Law, bars and restaurants as a whole were not adversely affected," said James K. Havemen, Director of the MDCH. "We commend Michigan bars and restaurants for their support in transitioning to a smoke-free environment as this law has also drastically improved the air quality in these establishments. There is no question that Michiganders have a healthier environment because of this important piece of legislation."
