I was 15 when I had my first, then deliberately turned into a smoker just to prove how easy it is to quit (I properly started when I was 17.) It took me 2/3 years to get properly addicted before deciding "nope, that's me done. Enjoy yourselves guys."
I do miss the banter in the smoking area of pubs though.
