Thank you all for your input. I figured the odds were not in her favor if she continues to see these people, just hoped I might read a success story against those odds. It seems pretty clear to me what she should and shouldn't be doing to work on her recovery.
Jerect - She said she was smoking oxy, although she referred to it as heroin a few times. She said it was because the highs are very similar, but I still have questions about that. From what I have read, many oxy addicts turn to heroin since it is so much cheaper. I have known her most of my life... we were family friends growing up. We have grown apart over the last couple years, but I wanted to be there for her when all of this came to a head. I live a very good (and responsible!) life so I you make a good point: Distancing myself may be best. I really want to be supportive and not give up on her too early, but if she isn't truly dedicating herself to this then I am wasting my energy. I can't do it for her.
Thanks again everyone for your thoughts - it's very appreciated!
