I've heard a story of a couple from west coast where she got a good job in DC. They laid off the weed a month in advance, but that wasn't enough - she still couldn't pee clean. So after a few tries she just gave up on the job and returned to the west coast - with all the cost of it draining the family budget. So they were practically punished for having traces of something they did at home where it was perfectly legal.
