You've got to talk to your kids about these things, but it has be ongoing. I think it's an excellent thing. The kids know it all, but I think the parents are left in the dark. You can't tell the parents to say, 'don't do it' because most kids will probably rebel against that. There are kids who don't mind talking about this sort of stuff with their parents, but there are also kids who say, 'I don't want to go there with my parents'.
People do drugs because they have deeper problems.
Maybe if I was younger I would listen. If your parents didn't give you a lecture, but talked to you at your level, it would be better. If you were 12 you might listen to your parents, but once you get older you listen to your friends. They should do something about drugs. I don't know anyone who has got a bad problem.
