Xanax can be a dangerous and addictive drug. Docs did not realize how addictive it was when it first hit the market. If she's addicted she needs to get off it slowly and carefully and with a docs help. This is a shame really.
Oh, get real will you. She's got issues much worse than that. Xanax is safer than valium and anyone who thinks otherwise needs to up their beta blockers. You're missing the forest for the tress.
It's safe but addictive. If you try to get off it in one fell swoop you will get withdrawal symptoms.
