im currently cleansing my body of thc, i have court in a week and ill have to go to a 3 day rehab clinic where i will likely be tested, so i decided ill just quit now and call it a tolerance break, i've been running about 2 miles a day, eating minimal fats, take lots of vitamins and drinking about 12 quarts of water a day, i have a few at home drug tests my friends giving me cuz his moms a nurse so lets see what happens, but i would say unless you just get a faulty test, you're fucked if you smoked more than a week before it.
