I guess your comment is case in point. People still don't understand psychological addiction. Yes, nicotine is addictive, but it's a small component of cigarette addiction. If it was just about that then patches would be 100% effective (in reality their success rate is dismal) and people who never smoked would use patches to get a "hit".

So I guess you could think of it the other way around. If you can believe scrolling is addictive then you should also be able to believe that putting a stick of burning plant matter in your mouth is addictive. Once you open your mind to the reality of psychological addiction you'll see it everywhere.
