We conducted randomized time–location sampling surveys of young adults (aged 21–30 years) in 7 LGBT (n = 1113 patrons) and 12 non-LGBT (n = 1068 patrons) venues in Las Vegas, Nevada, in 2011, as part of a cross-sectional study of a social branding intervention to promote a tobacco-free lifestyle and environment in bars and nightclubs. We compared exposure to secondhand smoke (SHS) and attitudes toward smoke-free bar and nightclub policies among patrons of lesbian, gay, bisexual, and transgender (LGBT) and non-LGBT bars and nightclubs.
