Like everybody else said, shouldn't be a problem as long as you handle it well.

You were a kid, you made a kid's dumb mistake. You learned from it, you saw the error of your ways, you moved on, and have been a responsible human being ever since (I hope).

As long as you take responsibilty for it, I'll bet that if it comes up in an interview, there will be less than 2 total minutes spent on the topic, if that.

The only thing might be if the interviewr takes the "bad cop" stance to try see if he can rattle you. You know, starts asking if you were always irresponsible, have problems exercising good judgement, trying to put you on the defensive about it. Dount it will happen, but maybe.
