Having "just one" works for some. That's the way I managed to stop. I don't think the addiction is like alcohol when, I am told, "just one" can be fatal. I stopped 23 years ago and am no longer a nicotine addict. I abhor the sight and smell of tobacco and won't allow ANYONE to smoke in my house or car. I could have "just one" but I'd probably be sick and have to persevere and learn to inhale all over again. I do however feel sorry for my hero Bob Dylan who can't have a cigarette in any public place in California, tho I wholeheartedly support the ban.
