I can't say I follow how the lack of medical marijuana accelerated the degeneration of his hip, since its purported medicinal effects are only really documented for glaucoma and pain control, if he has such a quack approach to medical marijuana and it is known in his area ('It makes me feel good, so it must be fixing the illness') then I can see the felony conviction may not be the only thing keeping him from getting a job anywhere near his home.
And seriously, if he had enough of it that they pressed a felony case and property seizure, it wasn't just for his personal use. Get real, DUmmies. He's amazingly lucky they didn't just seize the entire farm.
