I used to be a social smoker kinda like you, then I started buying a pack here and there. I smoked a decent amount for prolly 4 months, something like 4-5 a day on average, and only felt somewhat physically addicted. It was my chest and lungs that told me it was time to stop before I didn't have that option. About a week of not smoking I already noticed an improvement. Sure they are "fun" for whatever reason, but its not worth it.

My main thing for smoking as many as I did was my long drives I had. The drive is boring, so a cig seemed to keep me occupied. Now I just smoke a bowl or something and I don't even think about cigs.
