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.
