And for some reason we only use "addiction" to describe things that are recreational in nature, not drugs that have no recreational use but can be quite dangerous to discontinue abruptly.
Substances like caffeine, sugar, and painkillers are definitely still referred to as “addictive”.
Whereas substances like sertraline (antidepressant) are referred to as a “dependence” because it’s dangerous to discontinue abruptly (as you said) but there isn’t any psychological addiction involved.
