Chinese emporers were controlling opiates all the way back in the 1700s and the British were tied up in war for 20 years over the wreckage to the Chinese addicts.
The doctors, all college educated, some of our most studied and intelligent citizens, they knew about the history of opiates and im not talking about the dare campaign. I knew before the epidemic even got into force when I tossed the opiates I was prescribed in the trashcan.
The oxy marketing was just the wink and the nod everybody needed to convince themselves to parrot with a straight face, but they didn't actually really believe it.
