I find its always down to the parents fault if your child starts smoking, taking drugs, underage sex (anything like that.)
Concently telling your child it is the wrong thing to do-they will finally get it in there brains.
The mother on that programme, i find, isnt doing enough-any parent can stop there child just need to use the right technics. I would of never started smoking or bunking of school because i knew if my parents found out i would be in a hole lot of bother.
A 13 year old smoking is stupid and should be sorted out.
Children learn of there parents. Many of my friends in my teens smoked and i could turn around and say no, so you cant blame pier pressure.
