Hey Rippy - You're right - that sounds extremely excessive, not to mention expensive. It's not even fun or relaxing to be THAT high.

Why do you think they're doing it? Do you think it's truly addiction, or are they locked into some kind of fatalistic mindset? How old are they? Are they holding jobs?

I have more questions than I do suggestions. You can't MAKE them stop, obviously. I like Jennie's suggestion, though. The only other thing is I would suggest, if it were my friends, is to talk to whoever they're getting it from. A real dealer wouldn't give a hoot, but if they're getting it from a friend, then maybe the friend could back you on an intervention.

My last suggestion is that you get yourself and your girlfriend out of that house. I don't know where you live, but if you're in a city, then you really are putting yourselves at risk to live in a house that has that quantity laying around, since smoking that much is probably smell-able outside of the house. If they get busted, then so do you unless for some reason, they take the blame for all of it (which is not likely to happen if they are feeling panicked).

Good luck,
