Oxycontin has its uses and benefits. No doubt. The problem is that the manufacturers thought that's not enough profit. So they expanded their target market and pushed it on people for whom it was a harmful choice. To do this they lied about the necessary doses perfectly knowing that this was a lie. It's the same playbook the tobacco industry used (still does?). Lie about known problems with your product while at the same going all out on sales.
