I would expect it's pretty easy to find in Wichita, as it is in most cities anymore, especially after hearing she struggled with usein before. She knew someone to call to get started again. And meth is cheaper than drugs like cocaine... substantially cheaper. And while she looked like a user, she didn't have a lot of the signs of a heavier user (scarring, scabs, etc), and my now recovered ex-roommate said once, you could get "feeling good", but not be so overboard you were an obvious user for under $100 a week. With 2 kids and a household to purchase things for, it wouldn't be exceedingly hard to funnel even $100 a week to that instead of groceries or household items.
