"Young girls on Twitter were cutting themselves, self-harming to get his attention to get him to stop.
But I don't think Justin should do something where he would get caught, so that his young fans aren't influenced.
Imagine when those little girls are adults and they have kids and they ask, 'Oh mum, where did you get those scars?' How do they respond? 'When I was 12 my favourite singer smoked marijuana.' I think it's very irresponsible of him to do that!"
Sounds like pretty reasonable advice to us!
