. Then ask your self who is smart and buy's urine and uses a heat pack or
condom full of clean urin to avoid detection usually the paid class that is
paid more money?

When I have been tested (CDL) they give you a very short period of time to
report for the test, and you never know what day the test will be. You would
have to have your clean specimen ready all the time, and I'm not sure, but I
think they can tell from decomposition factors, if it is fresh or not, and just
being warm is not the only factor involved.
