I reside in Las Vegas and got a job where, even though I had to take a drug test to get hired, I told the manager about my MMJ rec from Cali, showed it to them, and then tested positive on the test. Still got the job, but only because I told them first and showed the rec. Now I just need to get my NV ID so I can get the card out here. But Cthulu and FSM bless MMJ in any state that has it! But yes, all of the casinos do a hair test for jobs, most of the service industry jobs will require at least a urinalysis.
