Had Walter White from "Breaking Bad" lived , he would be manufacturing opioid painkillers. And his target market would have been whites. His customers who weren't satisfied likely wouldn't be around to complain.
According to the CDC, overdoses from prescription painkillers have increased fourfold between 1999 and 2011 for whites. That's what John Tozzi reports in Bloomberg Business Week. Here you can read that quick take.
That might be because it is amazingly easy to get a prescription for those opioid painkillers. Medical doctors and dentists offered them to me for minor pain problems.
Because it is so easy to obtain those pills legally, there's a brisk business peddling them illegally.
This isn't just street action. In the residential complex I had lived in for seniors and the disabled in Connecticut, middle class whites with a history of pain became known for their pill stockpiles. That's how they were able to pick up some underground earnings. Since Medicaid and Medicare covered much of the original pill cost, the percentage of profit was high. None I knew ever got nailed.
