I think it’s because they’re using it for aesthetics and not just health improvement.

Getting healthy and getting skinny aren’t the same.

In medical/pharmaceutical context isn't "abuse potential" specific to drugs that feels good/get you high... Like street drugs? In the case I think OP means that people is abusing for the results instead. Like people that do too much plastic surgery and loose track of what they first wanted to improve.

All my knowledge about ozempic comes from a south park episode. From that and tabloid news it seems like a lot of people use it for non medical purposes
