According to our psychological theories any sufficiently fast acting and strong painkiller will be addictive as long as it removes or reduces any type of pain.
Seams strange if this one truly will not have "drug abuse" connected to it.
The impression I got from Wikipedia reading about this (suzetrigine) is that it’s not addictive because it acts on peripheral nerves and not directly in your brain
Given how scared people are of "addiction" the seller certainly would like that narrative and it might make sense from a withdrawal perspective. Which in turn has an effect on how addictive a drug is to a very large degree.
There are also lots of studies indicating that the speed of action of a drug is important for addiction. Which essentially boils down to the fact that the brain (beeing effected by operant conditioning) needs a drug response that is sufficiently noticeable to be connected to the action of taking the drug.
