The only sure way to know is to test yourself now....and again later if you are still positive. Keep up the exercising and make sure you add metamucil about 3 times a day. Metamucil will help excrete the THC from your body faster via your stools...which is how 70-75% of THC metabolites leave the body. You want to STOP exercising and START eatting fatty foods about 3 days before test so that your body is not burning off body fat that could have THC metabolites buried inside. One other thing...if you want to pass your test, study this forum for lots of helpful hints. If you study, you can possibly pass. Good luck and please post results.
