I don't believe having the documentation will be an issue as its not against the law (in medical states obviously) to posess a card. However, if it's a company policy to pass a drug test, at any time during employment, and you fail, then it won't matter on the legality, as it's a company policy. If your employer says you can't fart at work, and you do, and they have proof, they can follow through with policy. Especially if you live in an "at will" state.
