Diet and exercise will work a bit ... stay away from fatty foods ... eat lots of salads and veggies, stay away from meats for a little while ... fatty foods add fat to your body ,and the fat tissue holds onto THC longer, than lean tissue and muscle...

Exercise to your dripping with sweat ... several times before the test. ... this helps clean out what your fat tissue is holding

... and drink lots of alcohol ... the hard stuff ... THC isnt water soluble ... alcohol is

Good Luck
