Casinos often allow smoking indoors and can be a source of involuntary SHS exposure for employees and visitors. We examined attitudes toward smoke-free casino policies among US adults. During June and July 2017, we used a web-based survey to ask a nationally representative sample of 4107 adults aged ¡Ý18 about their attitudes toward smoke-free casinos. Among 4048 respondents aged ¡Ý18, 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%). Although the sociodemographic characteristics of respondents who favored smoke-free casino policies varied, the majority in each group, except current smokers (45.4%), supported smoke-free policies. Allowing smoking inside casinos involuntarily exposes casino employees and visitors to SHS, a known and preventable health risk. Further assessment of public knowledge and attitudes toward smoke-free casinos at state and local levels may help inform tobacco control policy, planning, and practice %K secondhand smoke %K smoking %K tobacco %K public attitudes %K policy %U https://journals.sagepub.com/doi/full/10.1177/0033354919834581
