title: Smoke-free home and vehicle rules by tobacco use status among US adults.
abstract: OBJECTIVE
  To assess the prevalence and characteristics of smoke-free home and vehicle rules by tobacco use.
  
  
  METHODS
  Data came from the 2012-2013 National Adult Tobacco Survey, a telephone survey of adults aged ≥18. Respondents who reported smoking is 'never allowed' inside their home or any family vehicle were considered to have smoke-free home and vehicle rules, respectively. Prevalence and characteristics of smoke-free rules were assessed overall and by current tobacco use (combustible only, noncombustible only, combustible and noncombustible, no current tobacco use). Assessed characteristics included: sex, age, race/ethnicity, education, marital status, income, region, and sexual orientation.
  
  
  RESULTS
  Nationally, 83.7% of adults (n=48,871) had smoke-free home rules and 78.1% (n=46,183) had smoke-free vehicle rules. By tobacco use, prevalence was highest among nonusers of tobacco (homes: 90.8%; vehicles: 88.9%) and lowest among combustible-only users (homes: 53.7%; vehicles: 34.2%). Prevalence of smoke-free home and vehicle rules was higher among males, adults with a graduate degree, and adults living in the West.
  
  
  CONCLUSIONS
  Most adults have smoke-free home and vehicle rules, but differences exist by tobacco use. Opportunities exist to educate adults about the dangers of secondhand smoke and the benefits of smoke-free environments, particularly among combustible tobacco users.
