Right, Purdue Pharma—the sleasebag Sacklers—were unethically pushing OxyContin (oxycodone) but the unethical tactics that Merck adopted in marketing its NSAID Vioxx seems to have been forgotten. Vioxx was withdrawn from the market and Merck paid out billions in law suits.
As I've mentioned elsewhere, the Vioxx scandal is every bit as big as the Purdue one. Check this Wiki (lawsuits): https://en.wikipedia.org/wiki/Rofecoxib
If you've time watch this YouTube video on Merck and the Vioxx scam (if you weren't aware of the facts you'd think you were in Palermo/Mafia territory): https://m.youtube.com/watch?v=K0GrFnOpJoU
