There are lots of evil influences that can be visited on growing kids, many if not most of which come from parental example.

I'm delighted to say that my two (21 and 19) don't smoke or take drugs and claim to have never tried, despite the availability, as they are both extremely social animals. They drink socially, don't do religion and will not smack their children if/when they have some. I'm so proud.

Cheers, Terry

p.s. on-topic, well done Charles, for a bit of constructive parenting. And those who have posted saying that drug-taking is "normal" must live in a very narrow little world.
