Dude your fine, everything is done and over at this point, everything the cops took was legal to have, so they arent going to be calling up your parents, the school doesnt have rules regarding synthetic urine, so there is no point in calling your parents on that fact, the lighter and listerine.... wtv whos gonna care about that. in 3 months your gone and the results will come in, at this point the school isnt going to even bother.
