Honestly, that sounds very conspiratorial and baseless. It assumes doctors are idiots and drug producers are comic book villains. Reality is more nuanced.
> Purdue has known about the problem for decades. Even before OxyContin went on the market, clinical trials showed many patients weren’t getting 12 hours of relief. Since the drug’s debut in 1996, the company has been confronted with additional evidence, including complaints from doctors, reports from its own sales reps and independent research.
Comic book villainy quickly dissolves into nuanced realism when you distribute the elements of the "conspiracy" over the org chart. Then you end up with a lot of people who wanted to believe and mutually reassure each other that everything was fine, resulting in collective blindness to the evil they were doing.
