I don’t know how to distinguish physical vs. psychological addiction. The person I’m referring to as the “addict” had no physical reasons for smoking weed, but did have problems with depression, and took meds alongside the weed.

I do know people who smoke pot daily, whether for medical conditions (pain, mostly), or just relaxation, like a drink of alcohol. And I consider none of these other people addicts.

I’m not sure if I’m answering your question.
