When I was smoking (quit, cold turkey, almost twenty years ago), I was a pack and a half a day.
On race day, I took four packs to the track with me, and I was smoking butts on the way home.....
Wow. When you are down to smoking butts you are gunning sticks really fast. Damn. That’s impressive really. Your lungs probably don’t think so, but outside of that, that’s pretty impressive.
