<human>: So I've had a best friend since 8th grade. In high school we drank and smoked pot (a lot) but towards the end of junior year I kind of stopped and she got more into it. She started dating a guy who was a huge stoner and used to do harder drugs. He's also very controlling and during senior year I saw bruises but she always claimed she just got them by falling or banging into things at his place (once came out that one was definitely from him grabbing her arm so hard). Now we're graduated and don't talk as much since we go to college in different cities. She's still dating this guy and she's starting to do cocaine. She told me the first time she tried it and said it wasn't that great and that she wouldn't do it again but now she posts pictures of lines and all kinds of shit on tumblr (obviously stupid posting things like that in a public forum). Now my question is what I should do? She's a really smart person, I just think this guy is bringing her down. Is it even worth it to try and talk to her? We've gotten in fights before when I've tried to tell her that the things she does worries me. Or would it be better to just let her do what shes gonna do and stop being friends? I'm not down to be around people that are using coke. But an ultimatum is kind of lame since we're friends, not like dating haha. Okay sorry this is so long.

Give me the gist of the text in a nutshell
<bot>: best friend of 6 years is in an unhealthy relationship and starting to get into cocaine. Should I talk to her about it even if it'll start a fight or just stop talking to her?
