What's up with people asking if it's all about "the action?" He's obviously concerned...
Anyway, you've got to do what you can. No more should be expected of you. When she's done digging a few more feet of her grave, let her know how you feel w/o beating around the bush. Let her know exactly how you felt when you saw her suck that sh|t into her body.
As you've stated - you can't make her change. All you can do is set a good example and be a nice big shoulder to lean on when she needs it. But, tell her it's either you or crack. No in between. Lies will not be tolerated. If she'd rather get high than hang with you, that's her loss.
Drugs are some amazingly powerful things. Don't underestimate them, don't kid yourself. Do what you can to help, and you'll be a better person.
How's that for encouragement?
