I don't not subscribe to the idea for one moment that any doctor told any patient that opiates weren't addictive, nor that anyone would have attempted to sell that to any Dr. They aren't that dumb. We've known that opiates were addictive for over a thousand years.
This entire premise is based on the lawyers filing the lawsuits. It's a brilliant populist idea. You disavow the junkie from their actions, because... they didn't know that eating 13 perccocet a day would lead to an addiction, and their Dr, who gave them a 2 week prescription of 28 pills, three years earlier for an injury can't be held responsible, because nobody told them that opiates were addictive, (except their entire medical school, every year of their residency, and their career), and places the blame squarely on big pharma, who we all hate. Nobody ever told anyone that opiates weren't addictive, and you don't start buying heroin from Juan on second street because you sprained your ankle once and took pain pills for 2 weeks and then you were hopelessly addicted.
It's all bullshit.
And I had a monthly perccocet prescription from the VA for 8 years myself, and then I finally realized that it was stupid and I stopped taking them. Had about 3 rough nights and never looked back.
