start drinking tea everyday starting now. any tea from the camellia sinensis plant. tea contains polyphenols which induce the cytochrome p-450 enzyme in your liver which metabolizes THC metabolites. eat garlic; garlic enhances both phases of the body's detox system (the second phase changes all fat soluable toxins to water soluable toxins to be excreted.) get to a sauna and sweat, drink lots of water while you're in the sauna. keep fat out of your diet until the day before the test. that is some basic stuff.
