(This is similar to another open topic about talking to your kids about drugs, but this is about confronting your kids when you discover that they've already gotten some drugs)

Over the weekend I discovered a one-hitter pot pipe in my son's possession. He hasn't been displaying any of the tell-tale signs of drug use - his grades haven't dropped, he hasn't become more secretive, his personality is as normal as a teens ever gets - so it came as a bit of a shock.

I don't know why I'm so surprised. I smoked pot when I was his age. Most of the kids I knew did. I think it's because I'm not ready for him to be so old yet.

I was torn about this for awhile, worried that if I told him to stop, or forbade him, I'd be a hypocrite. I smoked for years with no ill effect, and turned out fine... but a lot of my friends from high school burnt out pretty bad. I can't wager my son's future on him having the same good sense I did. I can't guarantee he'll grow out of it like I did. I don't want him living in the basement smoking out ten years from now.

I'm talking to him tonight after work. I'm not entirely sure what to say.
Forbidding him to stop wouldn't work on me when I was his age, and I doubt it'll work on him.

Any advice?

This is one of those mileposts that you wish you don't have to reach. How old is your son? Whatever you do, win over his confidence that you are on his side, try to find out what's going on with him and let him do most of the talking. Then take it from there.
