xtcrider if you don't notice any difference it must either be because you were somehow weirdly just as fit before you stopped smoking, or because your bottleneck is muscle strength rather than cardiovascular stamina/lung capacity - it's perfectly feasible that the latter is the case.
It might just be that you don't notice the effects, but if you're still really sceptical try this: take up smoking again, then after a week, go swimming. Swim as a smoker for a week, and time yourself over 25/50 lengths or whatever. Don't completely bust a gut, but don't dawdle either, just swim at your maximum comfortable pace. Then give up again, and carry on doing the same swimming at the same time of day, and see if you notice any difference in your times.
I think part of the reason people go faster when they've given up is because they feel they should be able to, so push themselves that bit more - but there could have been other reasons for that little push if they hadn't given up smoking, it might have just had them panting a little bit more.
Possibly if you've been timing yourself over a course you know well then you've built up a memory of how much energy to use and conserve on which bits, which is acting like a kind of inbuilt cruise control switch.
Also what sort of cigarettes did you used to smoke and how many a day?
