I know that if I would ave had access to birth control and condoms and so forth in highschool, it would have been bad news all the way around. I cinge at some of the stuff i did when I was young,and it was all a ploy to be cool, and to show my friends I wasn't afraid to do stuff. Really sad now.
I agree that if the parents don't know all the substances that a child takes it can be bad news, especially if the child is too embarassed/afraid/incompassitated to tell parents durign a real situation. Uck. Bad news all the way around.
