Witt doctor dope they get a card because they have insomnia or headaches or pain that allows them to buy the dispensary dope.
It takes nothing to get medical marijuana.
We know someone who got prescribed medical marijuana for persistent headaches. He got into an accident sometime later while on the job. Since he was working, he had to take a blood test. When it showed drug use he was fired on the spot. He had signed an agreement upon taking the job that, among other things, he would not use drugs. He’d never thought about that until he was fired.
