I don't find drug tests humiliating, but they're certainly an invasion of privacy and result in unfair discrimination. Someone smoking pot now and then doesn't make them a bad or unreliable person.
That was easy enough for me... I guess I'm just comfortable with my penis.I had a lot of random drug tests in the military. It humiliating because someone has to look at your dick while you are pissing in a cup. How could that not be humiliating?
