This Thursday is the Great American Smoke Out. Anti-Smoking groups like the American Cancer Society and the American Lung Association have asked people and businesses to stop smoking for one day. They made a request to the Iowa Gaming Commission to participate, but this request was denied. Currently, casinos are one of the few places in Iowa where smoking is allowed indoors. Casino’s like Riverside Casino and Golf Resort will still allow smoking on Thursday. They say they do a lot of things to accommodate both smokers and non-smokers. They think adults should be able to make the decision for themselves in venues that are meant for only those who are over 21.
