Right, there's a difference between a chemical that will addict most people simply because of the changes the chemical makes to the brain (even if the person doesn't even really like doing the thing that causes them to consume it), vs. an activity that gives you dopamine hits and can be addictive, depending on the person.

One is physical addiction and the other is psychological.

But I'm also feeling a parallel here to people who think that mental health issues aren't real medical problems and that people can just "get better" whenever they want. And that's concerning. We shouldn't be more lenient on things that are "only" psychologically addictive.

It's predictably addictive under common circumstances (a lack of socioeconomic support and a lack of alternative means to occupy one's time). If those circumstances are becoming more and more widespread in a society (which they are in this one), it behooves experts to consider that "typical" and "this particular cohort" might become harder and harder to distinguish, to the point where what would have been targeted interventions need to become general.
