youll probably be fine by the time you get a job, first time so theres gonna be only a little thc in your cells. THC is fat soluble so if youre 5'5" and 555 lbs and smoke an oz a day, have fun getting it out of your system. you sound pretty in shape and stuff, keep your metabolism high (lots of energy, work out alot, eat good food or whatever, basically be active.) and youll be clean of THC pretty soon. weed stays in your hair for like...a long time though...idk anything about hair tests..
