I know this has been discussed on here before but i need fresh answers. i was told by a man claiming to be a forensic scientist who said certo along with asperin and vitamin b12 will gaurentee a pass on a urine test for pot. i havnt smoked in 24 hours, my test is tomorrow at 6 pm. do you think this method will work and why: take 1 certo with bottle og gatorade 2 hrs prior to test with 2 asprin and 2 b12, drink bottle of water 1 hour before test repeat process. by now you'll have to piss bad. pee 3 times, drinking 8 oz of water after each piss and go to your test. give them a sample mid-stream and you should be fine.
