These meth labs are sprouting up all over the rural US. Crank has become the drug of choice these days. It can be made from basic household chemicals plus cold medicine and match heads. "Cooks" can operate in isolated shacks, trailer parks, motel rooms or the back of a car.
Punch up "meth lab" on google images and you'll see an array of them, plus mug shots of the very pale and thin cooks.
The operations are VERY profitable and would seem an ideal way for a degenerate, rural cult in the US to make $$ to support its activities. A cultist is bad enough, a tweaker cultist far worse.
The operations are well armed, as well. Here's one arsenal found at a meth lab in Alaska:
