The only effective way to rid the body of THC is to exercise. I would recommend cardio along with pushups, situps, and squat thrusts. You can also add a high fiber diet(Metamucil works great) to help excrete some extra THC through your colon. These things and time alone are the only way to get clean fast.
Absolutely correct, the only thing I would add is to maintain a steady flow of electrolyte rich fluids to help flush your system.
