He or she takes our pee, blood, or hairs and obsesses over them (like some kind of fetishist) to try to learn something about us that we would prefer to keep private.

lol.

I really hate those drug tests. When I was still working for a corporation, it felt really humiliating and uncomfortable to submit all those stuff to them. The tester even asked me to leave the door open just so I won't cheat lol. Then if I don't pass the test, I don't get the job of course. Forget about my skills. But clearly, I'm not an addict. Not a legitimate hazard either lol. I'm just glad I don't work for them anymore.
