Judy, the "man" of the house has been in jail for dealing meth and trying to kill his wife whilce under the influence. Considering how unpredictable that stuff makes one, no one wants to risk dealing with him because he simply can't be trusted not to just go off on someone.
Not to sound snotty, but I do think they're keeping themselves "clean "right now, because since their last arrest they've all packed on weight like crazy and while doing it they dropped it just as quickly.
I don't want to steal their food from them, but I do want an end to this nonsense as soon as possible.
