Well, where I live, smoking in public places (ie. bars, restaurants etc) has been banned. It initially caused a big fuss in the smoking community as well as the restaurant/bar owners (due to lost revenue). A few years later, not much complaining being done by the smokers...they simply go outside when they need to light up. Bars are smoke free and IMO, everyone is much happier....and safer. What's the point of this: if it affects your health and ONLY your health, do what you want, but if it affects other people's health and well being, you have a reponsibility to take extra care. Wait till you get of the boat or ask the other divers if you can borrow their spot for 5 min. until you finish your cigarette as to not inconvinience them. Ultimate solution, stop smoking Won't solve the world's problems but certainly won't harm us!
