Imo, AA na is the LAST place a young person should go. Have u looked into smart recovery or life ring or just Google alternatives to AA/NA. I think suboxene, I think I spelled that wrong, but I think it's a good thing to look into. Also naltrexone is another med u could have her try.

But I would stay far, far away from 12 step programs, I was very abused by many ppl I met in them. And they are completely dis-empowering, patriarchal and shaming. Good luck.
