Forget those gloomy predictions about bars and restaurants being driven out of business if their customers were not allowed to smoke.
An Arizona State University study found that the statewide ban on smoking inside businesses has had no impact on 96 percent of bars and restaurants surveyed.
Of the remaining 4 percent that said they were affected, some said business had improved after the smoking ban.
The voter-approved ban took effect in May 2007 with opponents saying it would bankrupt businesses.
Instead, bars and restaurants have added outdoor patios and adapted. Some businesses closed, but none blamed the smoking ban.
It now is healthier and more pleasant to eat and work in Arizona restaurants. So everyone has won.
