Key word—daily.

And I am going to assume these individuals have a serious physical injury or illness that they regularly need those painkillers.

Wanna try for untreated scoliosis that requires another’s assistance to get into & out of bed & hope aspirin kills the pain?

Or have a piece of tendon grafted onto another & assume the pain will go away all by itself in two weeks or less?

Wrong on both counts. And a person who takes the dose prescribed for that particular pain only isn’t an addict. They’re taking what they need to manage that level of pain.
