That sucks about being grounded but that's life bro. You must've done something to piss your parents off. If you don't wanna be grounded then move out and be your own man. Realistically that's practically impossible so if i were you i'd smoke the swag in a blunt or g bong and try and get on better terms with the folks if possible. maybe sneak out at night and buy some headies, think, you have time.
