Someone I was once friends with had been a drug addict while in the military, where they do random drug tests and throw you out if you fail, basically. I asked how to beat the drug test if I needed to, as I had been unwillingly exposed to secondhand marijuana smoke while job hunting. He assured me it would not matter, as secondhand smoke would not show up on the test, then gave me detailed instructions on how to beat the test "even if you are so high you have trouble peeing in the cup." So, maybe don't believe all test results.
