Not to burst your bubble marine, but ive had some friends with cards, still be fired from dirty test. Medical cards are a new thing, and not accepted by most workplaces, if any, they need to adjust that policy, since its a booming thing, and damn near about to be on the ballot. But yea, some companies are old fashioned and a dirty test is a dirty test, regardless if u have your card, kinda sucks, but u can always use the fake urine pouch, that works for sure! its about 40$ or so at a local smoke shop! some come with handwarmers to keep it at normal body temperature!
