Suspected DS2 15 of smoking a couple of weeks back and yesterday found a lighter in the kitchen.
Asked him if he had anything to tell me and as first he said no, until I produced the lighter.
Confessed to smoking 4 spliffs since the start of the school holidays and a few cigarettes.
Calm conversation continued on both sides, assurances that he won't be doing it when he goes back to school, but maybe in half term 
At a loss of how to deal with it. I'm horrified, ashamed and angry. Can't see banning him from seeing his mates will work or grounding him.
He wants me to trust him when he says he won't get addicted but how the heck can I believe that?
