I am a rare smoking diver unfortunately. In the process of trying to quit ( I am on Chantix and waiting for it to build up in my system before my quite date in a couple weeks )
This is exactly the reason I am quitting though. If it werent for diving, I doubt i would be nearly as concerned.
Rare in the US/EU/ANZ. Go East in Europe and down to Asia... As they say in Russia, he who doesn't drink and smoke will be a very healthy corpse.
