Controversial in general, maybe. In the case of opioids and the pharm industry, absolutely not. It's been well documented at this point that pharm companies were well aware of the abuse, and not only did nothing to stop it, but went out of their way to encourage it because sales were going through the roof.

In the case of Purdue and oxycontin, the culpability has in fact been established in court as well.

As for the coders, I find it hard to believe that they were so ignorant, naïve, or unintelligent that they had absolutely no idea what was going on. I just don't buy it.
