Resolved Question: 14 year old friend addicted to hard drugs. What can I do to help her?

I have a friend who’s only 14 years old and shes already addicted to Meth, Cocaine, Oxycontin, and X among other things. I met her in August but we hit it off immediately and I feel as if we’ve been friends forever. I’m really starting to care about her but she is always depressed at school because of her addiction and sometimes because she takes downers in the morning. Since my friend started using drugs (when she was 11) her mom started drinking and being crazy strict. She once told me she had sex with some boy to get Meth I have never met a person who’s as caring and overall as beatiful as her so her situation makes me depressed and sad. Her parents made her go to rehab several times but nothing has helped. I feel that I can help her, I just don’t know how.
