Input: A friend of mine recently started doing cocaine. She's in her mid twenties. I've had a lot of friends do coke of the years, and generally it's not a major issue, they do it once every while at big parties and such. That's how this particular friend started as well a few months ago. But I've had a few friends who have completely fucked out and ended up ruining their lives from it.

Recently she's being taking more and more often. Initially it became every weekend, then sometimes during the week, and now multiple days in a row. From what I can tell she started using around 4 months ago.

I've tried speaking to her about it but she gets really angry, and lies to me about it saying she hasn't done when I know she has. The other day (on a week day) I asked if she had done coke the night before and she claimed she hadn't. I later accidentally saw a text conversation between her and someone else talking about the night before's coke.

I've told her that I'm considering talking to her parents because I'm worried about her. She got really angry and told me it has nothing to do with me.

Would I be the asshole for telling her parents? She will know it's me and I'm sure she'll never speak to me again if I do. I'm willing to lose a friendship if it means she gets the help she needs
