probably not, my solid guess is that you will fail, anyways if you cant pass the legit way try getting some clean piss and if that doesnt happen then tape a visine bottle of bleach to your thigh, drink lots and lots and lots of water and take vitamins, and when you have to take the test fill the container mid-stream and then give it a good squirt or 2 of bleach. not so much that it reeks of bleach, but as much as you can without it being easily noticable. because i heard bleach screws up the results and can make it come up negative.
