Fact: I've examined many studies by funded by anti-smoker groups. Every one completely ignored bowling alleys, pool halls, bingo parlors, and other businesses that are heavily impacted by bans.
Virtually all of the studies on economic impact have been conducted by anti-smoker groups, or governments justifying their laws. But in 2004 The Empire State Restaurant and Tavern Association funded a study that was conducted by Ridgewood Economic Associates. It concentrated on small, independent taverns. They found that bars and taverns in the state have lost about 2,000 jobs, $28.5 million in salary payments and $37 million in gross state product. The response of the anti-smoker groups was predictable: they claimed that The Empire State Restaurant and Tavern Association was a front for the tobacco industry. This is a blatant lie.
