title: Smoking restrictions in the homes of children with cancer.
abstract: OBJECTIVE
  To examine smoking restrictions in households of children with cancer and their effect on biological measures of children's secondhand smoke exposure (SHSe).
  
  
  METHODS
  A sample of 135 parents of nonsmoking children with cancer who lived with a smoker completed structured interviews.
  
  
  RESULTS
  Approximately 43% of families prohibited smoking in the home. Children living in homes that prohibited smoking had median cotinine levels that were 71% and 52% lower than did those from homes with no and partial restrictions.
  
  
  CONCLUSIONS
  Parents should be directed to completely ban all smoking from the home and car to best protect their children from SHSe.
