Well, I think it depends. Laying down the law and having the addict in your house abide by it... can be two different things. I'm not sure an addict can always set aside his or her need to use, just because it's putting other things at risk. In a way that's sort of the "just say no" approach; sometimes it works but not always. I have learned that you have to be ready, willing and able to follow through on the "or else" but that's pretty hard a lot of the time, and we shouldn't judge folks just because they haven't followed through. The rest of the world is already good enough at that!
