I have been in situations like this but it was the other way around. My mom likes to pop pills and live off of the government. I moved. That is the only solution. She is a grown women and she makes her own mistakes. She should feel bad with dragging you down with her. I heard a saying. You either deal with the situation or you cut it out your life. You can love family at arms length and that is what probably needs to be done. You have to let ppl like that fall so that they can get up on their own.
