Earlier quoted context omitted.
Asking doctors to decide which research they should and should not trust based on their understanding of history seems like a more dangerous situation.
I dunno, "The history of all opioids we have ever encountered has always been associated with addiction" is not a particularly difficult concept to grasp, nor can I see it taking an inordinate amount of time to cram into their education.
In the case of opioids, doctors know they are addictive. They also unfortunately happen to be _extremely effective_ (for most people) at treating severe pains, and have to balance the benefits of pain relief (both in terms of patient happiness and the healing process) versus the risk of harm. I've definitely seen a shift in doctors' prescribing habits in the past fifteen years, in favor of starting with Ibuprofen or other NSAIDs, with the option to ask for a stronger prescription if pain is too much.
