The circumstances of the available answers in which you could potentially get in trouble for being around alcohol would be being at a party with alcohol in a place where it's against school policy to drink, and being with underage friends who are drinking at a school function. Although the rules on this will probably vary between schools and states, if you show behavior that could indicate underage drinking even if completely sober, and are around others who can be proved to be drinking, you could be at risk of facing equal consequences.
