From what I understand employments drug test are NOT, repeat...NOT observed directly. Best case is you empty your pockets then they point you to a bathroom with no running water of any sort with your cup and tell you to bring back out. Next scenario, there's more then one toilet and/or entrance and person will stand outside of stall to ensure security of sample not from someone else in different stall (or something to that effect). SUBSTITUTION is the way to go with ANY and ALL employment tests. It's SOOO easy to maintain the temp. Read substitution and practice a few times.
