Some companies require it for everyone. When I did consulting work for Home Depot, I was required to get a drug test. It didn't matter that I wasn't a W2 nor a 1099 for them but a W2 of a consulting company who HD hired to do a project for them, all of us had to be drug tested, with the reason being that Home Depot didn't think it was fair to test people working in their stores if the white collar people weren't tested too. My employer didn't require the test of anyone but since this was a big contract, as far as I know, no one refused. If I were a recreational drug user, it might have been a rather unwelcome situation to come up after years of working for the company where drug use outside of the office wasn't a concern.
