TOPEKA -- In 2010, a ban on smoking in Kansas restaurants, bars, places of employment and the lobbies and hallways of apartments and motels went into effect. A recent study took into account sales of food, alcoholic beverages and other items to determine the impact of the ban. The results of the Kansas Health Institute study showed a steady increase in sales each year, with the exception of a slight drop in 2010. The study does point out that many Kansans already lived in areas where public smoking was banned when the state law was passed. The study concluded the smoking ban is not associated with a reduced number of businesses serving alcohol in the state.
