It's hardly a new thing for "bad boy" musicians to live up to what is expected of them. It's a career move for them , and it's the stock-in-trade of the media.

Smoking's a bad idea at any age really, though tobacco is worse I'd say, especially with the stuff the tobacco pushers stick in what they sell.

I always remember when my son was about that age he came into the room and I was smoking a ciggy "Mum - Dad's smoking again" he roared. "AND IT's TOBACCO!!!"

As for the odd drink, don't most people let their kids have a sip or two from a pretty early age, as part of the process of helping them learn to use it sensibly? Whether it works or not I don't know. But so far as I've seen kids and adults with drink problems are at least as likely to come from non-drinking homes. Probably the best way to stop your kids drinking is to be a disgusting drunk yourself. And the same for other intoxicants.
