If you can be behaviorally addicted to gambling, or even more aptly eating, you can be behaviorally addicted to medication that doesn't give you any physiological dependency.

> The DSM-5 has re-classified the condition [ed: gambling addiction] as an addictive disorder, with those affected exhibiting many similarities to those with substance use disorder. They both activate a reward mechanism in the brain, causing dopamine release to reinforce repetitive behavior. Both often lead to loss of control.

Edit: to engage more substantively, imagine if your glasses gave you, say, mild skin irritation that progressively got worse with wear, but you chose to mitigate that and wear them anyway. I would rate it at that level.
