I have a lovely, kind, gentle friend whose 14 yr DS smokes. My DS, same age, told me 12 months ago he had seen him smoking and even spoke to him about it as he is a peer elected anti smoking counsellor.Personally I would want to know but decided against telling my friend as she had poured her heart out over her DS going off the rails, school grades suffering etc, all of which she claimed to stem from her DS hanging around with bad kids who smoke and drink. I cautiously asked about her DS smoking and she answered " never " and that she had asked him when she could smell smoke on him. He is an only child who seems to be able to wrap both parents around his finger. I have now seen him smoking myself and am questioning my decision. I have no wish to be shot as the messenger, which-is what I suspect would happen. What would you do?
