As the body stores THC in fat cells, regular exercise may help to break fat cells down and release THC into the blood for further excretion. However, while exercise might help the body metabolize more THC, exercising too near to a test may also cause a positive result due to having THC in the bloodstream. This means that a person who smokes several times over several days has consumed a higher THC dose than someone who smokes once, so they are more likely to test positive.
