it's really a hit and miss thing. u think they can't detect the
ingredients of the flush system in your piss? you're so wrong lor.
if they suspect you're flushing "it" out of your system they know
what tests will be appropriate for you. also, they don't necessary
have to test ur urine for drugs. for e.g, the hair can also be
used. certaind drugs like cannibis will stay in your hair for
several mths, sometimes years.
good luck brudder!
