Drug testing is absolutely degrading. Have to go sit in clinic waiting room with a bunch of druggies and scum, and being treated like a criminal by the staff. Piss on command. Yes, it’s disgusting and degrading. Putting up with that for a job is worth extra money.
Imagine the uproar if someone proposed that school teachers be drug tested!
It’s very easy to see why young people JUST SAY NO to a career that requires drug testing, and there is no longer a big surplus of mariners.
