Anyone ever got a citation from police for possession of alchhol as a minor?

well after my friend's graduation there was a party.Everyone was drinkin.i drank a couple of beers not too much since i knew i would have to drive home after.later on that night i drove a few friends home , they were all really drunk . we end up getting pulled over for no seat belts and the police officer says he smells alchol comming from my friend breathe. so they ask me if i had been drinkin also. so i admitted to having a 2 beers about 3 hours prior . They didnt charge me with a dui since they seen i was driving just fine, but gave me a citation for possession of alchol as a minor..anyone have an idea what might happen when i go to court?
