I subscribe to the theory, first voiced to me by a friend in the cancer research field, that it is not tobacco per se, but the additives that are used by cigarette manufacturers that are the most carcinogenic component. Therefore I smoke 100% tobacco cigars. Not a cheap option as most inexpensive cigars contain similar additives, but it works for me. I do try to be a considerate smoker and always comply with no smoking directives or requests, even if it means standing in the cold to feed my habit. I also drive small-engined, efficient cars. In answer to the original question, though, in the UK, apart from pubs, bars and restaurants (where there is often a non-smoking area), not many offices or other public buildings allow smoking, and pretty much all public transport is non-smoking. Germany, Italy, Greece, Spain, France and Turkey are all more tolerant of smoking than the UK, in my experience. Alan
