NO AMOUNT OF WATER WILL 'CLEAN' YOUR SYSTEM.

There, now that we got that out of the way, I'll get specific.

THC is stored in fat cells. These cells are eventually secreted in urine and bodily sweat among other ways. Drinking water will not 'flush' out your system because the THC won't bind to any of the water you drink. The reason people suggest water is that it can 'mask' the presence of THC by diluting your urine to the point where it won't be detected. Too much water consumption will send up a red flag.

What I suggest is that THE DAY OF your test drink atleast a gallon of water. If you're too lazy to do the math, that's 128/16.9. Thats how many bottles you need to drink. Do this a few hours prior to the test, so that when its time to pee, you have a clear, diluted sample. Also, try taking a B vitamin before hand, as that will re-yellow your urine.
