Now this went too fucking far.

Well, don't kick her out. At least let her finish her high school education first.

Boh1, try being supportive etc... Understand that she probably sees things a lot differently.

Did you try maybe a family psychiatrist\counselor? It might be expensive because you live in the states though ...

All I'm saying is don't punish her because no matter how much you do it, it won't turn things around and it will just put a wedge between her and her family and make it more difficult to recover.

i've recently started smoking weed and i gotta say.. it does not change the behaviour of a person.. unless u do it excessively. i still get all A's and B's. im still the same person i was before. but if she does other hard drugs then yes... she would probably change! what i would think u can do is... find her new friends... or a new hobby; sports, musical instrument, etc. BUT like someone else said the psychiatrist sounds like a good idea
i'm sorry to hear about all of this, i'm also going through some rough times. wish u the best
