This seems like such a strange place to go to get high on meth. I can't imagine being in the woods all strung out and not having slept in days. Just imagine the strange things you'd see and hear in the woods when you're like that.
I think the real point that needs to be made here though, is that this woman may be an idiot, but she may well have been one her whole life, with drugs not having anything to do with it. I've done lots of stupid things and a lot of those happened while on drugs, but I have never once used being intoxicated as an excuse for why I did something. If I did something, I either wanted to do it or it happened due to me being an idiot, drugs or no drugs.
