teens getting drunk

After prom parties happen, that is just a fact that must be faced, so what do you do?  Do you turn your head and act like you don't see it?  Do you just not allow your teenager to go to an after prom party or even prom all together?  Or do you host the after prom party yourself, you know, so you know where your teenager is and what they are doing?

Over the years I have heard of several stupid things that kids to do get drunk or high, but this takes the cake. Recently, kids have been drinking hand sanitizer to get drunk.
