I have friends that are in the same boat. They all started adding green tea into their diets, it seems to assist in the removal of THC, Which makes sense after all tea helps clear the toxins out of your kidneys & liver. I thought they were crazy, but it seems to cut down the appearance of THC by almost 2 weeks, so if you're in the position that you are tested & know when its coming you can take the gamble. I am not saying its a sure fire way but it seems to help.
