I dunno, every employer I ever went to growing up looking for work has required a drug test, but I'm in Texas. It's not really a problem though, there are tons of detox methods you can go and buy, either in stores locally or online, that are guaranteed to work (and they do). Besides, most places you only need to be clean for the initial pre-employment test, after that the only time they will test you is if there is any accident on the job. I was managing a retail store and smoked nearly every day, didn't affect my job at all and nobody ever suspected anything. It wasn't my business, I just managed it, but the only people I would be afraid of hiring would be meth/crack/coke/heroin users, definitely not marijuana users.
