text_1: This is more of a psychosocial or medical-legal question.  Nine-month-old boy in foster care with recurrent wheezing.  Visits grandparents every 2 weeks for 1-2 hours.  In two days they are going to court and want my recommendation.  The wheezing is aggravated after a visit to the smoking grandparents.  Most books don't say whether it's really passive smoking or if you just don't smoke when the child is there, is that OK?
text_2: If adults smoke in the house, but not when the child is visiting, is that associated with asthma?
