Among 4048 respondents aged ≥18, a weighted 75.0% favored smoke-free casino policies, including respondents who visited casinos about once per year (74.1%), several times per year (75.3%), and at least once per month (74.2%). During June and July 2017, we used a web-based survey to ask a nationally representative sample of 4107 adults aged ≥18 about their attitudes toward smoke-free casinos. We examined attitudes toward smoke-free casino policies among US adults. Casinos often allow smoking indoors and can be a source of involuntary SHS exposure for employees and visitors.

Research shows that there is no risk-free level of exposure to secondhand smoke (SHS) and that eliminating smoking indoors fully protects nonsmokers from indoor SHS exposure.
