30 years old, started smoking at 15.
I fluctuated depending on stress, but it was never less than 1 pack a day, and sometimes got over 2 packs a day. I was actually over 2 packs a day when I was gifted my ego 3 weeks ago, and it was much easier to just drop it than I thought it would be. I haven't bought a pack of cigarettes in over 2 weeks!
