Sadly I think this is the case for most medications and most doctors. Very few doctors nowadays dig into the weeds of illness and medication. It’s all textbook.
Sometimes rogan brings on these doctors to talk about disease and these guys/gals go into such deep investigative work trying to find answers for people. Right down to the molecular level including what certain foods may do to mitochondria while taking a specific medication, etc.
I’m always thinking “where can I find these doctors!?” They just don’t exist.
This happens not just with opioids but with antidepressants, biologics, add, arthritis, etc. I’d bet anything 90% of internists don’t have a clue the long term effect of these meds
