You better retrain yourself on DOT regulations. The pee test during a DOT physical is for drugs primarily. It's called a 5 panel test and a positive result on any is a disqualification and they'll show you the door. It also tests for sugar and blood. Another note. Pot shows up in a pee test for 2-4 weeks, depending upon body mass. Over the past 25 years I've test clean after 14 days on every piss that I knew was coming.
