Just never admit to anything, be as honest as possible without incriminating yourself, run up to your room and hide your stuff quick and descrete if you have a stash or a peice with you, and take a couple hoodies with you before you leave to bake. Wear one with the hood up while you toke, put it in ur pack, and put the other one on for home. Visine is highly recomended, it solves your red eye (a sign parents look out for). Use hand sanitizer to get rid of any smoke smell on your hands, chew gum for your breath.
