I see problems with this plan northern light. First off, you are trying to get a medical card so that your previous charge will possibly face less harsh consequences than if you didn't have it? The way the law I think will see this is that they won't. If you get your card AFTER you have committed a crime then I think it is useless. As far as smoking while you are on probation, I wouldn't even count on a medical card being all you need to be able to smoke. Depending on the doc you go to, they might do criminal background checks too. Correct me if I'm wrong.
