Sweating it out will work in the sense that exercise will get the THC out. Drinking water? Well, you should drink because you're exercising, but drinking water alone will do no good at all. THC is fat soluble, not water soluble. That and if you take your test and it shows you drank a gallon of water prior to the test, a red flag will pop up.

I'd say use a water-purifying tablet (learned this trick from an ex-narc officer) but they might detect that if they're running a lab test and not a on-the-spot test, so just run your ass off for a few days.

Good luck.
