I had been smoking for 25+ years (yes, I started VERY early in my life). During the most recent years I was at 4 packs per day (20 cigarettes each pack) and on odd days I would go up to 5 packs a day. I work for a cigarette manufacturer and actually my job requirement called for me to smoke/taste which has never bothered me as I have always loved the taste of (the right kind of) cigarettes (well, not all the trials we made).
I changed departments recently and I no longer need to taste so unconsciously I reduced from 4 to 2 packs over the past 6 months and about 6 weeks ago I just decided to quit as I am on medication and smoking while taking that particular medication increases risk for DVT quite dramatically.
I am lucky in that I have had no problems quitting at all (especially considering I am in a heavy smoker environment), no cravings for cigarettes and what's best, I have even managed to lose weight as I am on a self-imposed diet at the same time
But I still love the smell of cigarettes and I do not mind at all if others smoke around me (depending on the brand they smoke, some smell worse). I will definitely never be an anti smoker.
I agree that in non-smoking places, one smells many different things today that were being masked before. When airlines went non-smoking, that was actually one of the many complaints one could hear, even from non smokers. Somehow the smell of smoke is better than BO, farts, strong old-ladies-perfume, etc.
