You could go that route, and it would be tempting to do so. However, there's also the issue that this guy is probably crazy as hell given that he's all strung out on meth and all. God only knows what he'd do if somebody confronted him. What pofacedho said actually sounds better, just quit the stuff at least for the time being...... not judging anyone's DOC but it's a drug with a high addiction potential and this could be a prime opportunity to either quit permanently if she chooses or at least take a break to assure that she isn't getting hooked.
I take breaks regularly. If I ever think to myself "I NEED to do some meth" then I put it up and walk away for a time. Anything can be dangerous... a kid died from overdosing on water. Its the use, not the substance.
