I dive and I smoke. Usually about a pack a day. I know, I know, I need to quit. I want to quit and have a plan to do it at a certain date. My SAC is average of a .42 on a moderate working dive. Can't complain too much about that. I don't smoke for an hour or two before a dive, or at all on a boat. I usually dive from shore, though. BTW, I sometimes dive with a guy who has been known to keep a cigarette and lighter in a waterproof bag, and lights up on the surface swim back to the beach on shore dives
(This guy is not me) Good luck on quitting to all who are in the process.
