title: The effect of household smoking bans on household smoking.
abstract: OBJECTIVE
  Because household smoking levels and adoption of domestic smoking rules may be endogenously related, we estimated a nonrecursive regression model to determine the simultaneous relationship between home smoking restrictions and household smoking.
  
  
  METHODS
  We used data from a May-June 2012 survey of Philadelphia, Pennsylvania, households with smokers (n = 456) to determine the simultaneous association between smoking levels in the home and the presence of home restrictions on smoking.
  
  
  RESULTS
  We found that home smoking rules predicted smoking in the home but smoking in the home had no effect on home smoking restrictions.
  
  
  CONCLUSIONS
  Absent in-home randomized experiments, a quasi-experimental causal inference suggesting that home smoking rules result in lower home smoking levels may be plausible.
