“Except in a few cases of doctor-caused addiction,”

it’s not a few, it’s a lot.

prescription opioid pain killers like Oxycodone and Fentanyl are EXTREMELY addictive, with most people being addicted after using for only two weeks, and many after only a week.

I don't know the science of neuropharmacology, but it does seem that there is a genetic (or maybe congenitally-affected) subset of the population that can become addicted from one exposure to the substance: it's how they're wired.

I have experience with people who were neurologically impaired by Fetal Alcohol Syndrome. They certainly did not choose to have their vulnerable neural networks.

There is hope for them, but they have to be in extremely structured and controlled environments.
