This is a fun piece about Breaking Bad: are the economics and the chemistry correct?
The basic shape of the problem is illustrated by a late-August story out of San Francisco. A man in his early 50s bought some meth on Sixth St., sampled the product, and decided the quality didn’t pass muster. He chose to confront his supplier about it, much as one might complain about the purchase of any kind of good or service that didn’t meet reasonable quality standards. The problem, as it turns out, is that meth is a bit of an unusual product in that it’s typically sold by violent criminals. Complaining to the dealer didn’t reap a refund; it got the complainer tased, stabbed, and—adding insult to injury—mocked in local blogs for his misfortunes.
