Oh for sure, and there's degrees of addiction too.

I take prescribed stimulant meds and (assuming I remember to take them regularly lol) I get withdrawals if I forget to take them. I'm not selling valuable possessions or causing lots of damage to my life because of it but I am undeniably on the gentle, clinically-acceptable end of the addiction scale (not to diminish the seriousness of addiction here or anything, just trying to destigmatise.)

I've seen people who were full-blown kratom addicts before when I was younger and it really left an impression on me because I had the preconception that it was just a cool & fun herb. It made me understand that kratom use needs to be treated with due caution and that addiction isn't something that respects society's hierarchy of whichever drugs/activities are more acceptable.
