Ah, if I may, the problem is not so much that her husband sells medical marijuana while she is opposed to cannabis use.
The problem is that her husband (and thereby indirectly she herself) benefits from being one of the few monopoly suppliers of legal cannabis. Thereby giving her a large incentive to maintain the current regime where you or I go to jail for growing cannabis but her family gets to make lots of money.
Taking the coal analogy, it’s like someone being appointed to ensure that no one is illegally digging out coal on their own land while their husband runs the only legal mine in the country.
