The idea that opioids are addictive is a myth. People taking them are treating “pain” that isn’t diagnosed in the medical system. For example, joblessness. It’s an easy scapegoat for politicians to let them avoid dealing with harder structural problems.
Withdrawal from opioids is overrated. It’s unpleasant, but that’s it. Unlike alcohol or benzodiazepine withdrawal, which can literally kill you, opioid withdrawal is like a bad cold.
So, yes there’s adaptations, but it’s way overrated compared to the media hype.
I'm not following. I feel like you are trying to tell me the Sun isn't warm, and is in fact, cold. Opioids are most definitely addicting by any definition of the word.
