No, the addiction is irrelevant because you need to go over and ignore the anti-smoking campaigns and what's on the packs to become an addict in the first place. That's the point. It is a personal decision to start and it is a personal decision to continue (although it is of course not easy to stop once you are "addicted")

To start is a dumb decision one did at some point in the past. To continue is one that is no longer in your control once the addiction has taken hold.

It's not a personal decision to stay addicted. Let me tell you from experience. I wanted to stop. Yet, the cravings didn't let me until I had external forcing factors. Why should we deny other addicts that same help?
