How soon can you exercise after quitting smoking?

the sooner the better. smoking causes reduced amount of O2 to be taken up by the subject's red blood cells(as the CO carbon monoxide takes the place of oxygen) once the subject has stopped smoking the subject's body will immediately start to purge its self of all the nasty stuff that comes along with smoking. exercising will decrease the time taken for your body to clean its self out but it kinda boils down to a catch 22 either wait for a period and let subject's body clean out the impurities and it will be less of a strain when the subject does decide to start exercising ( however it gives a longer period for temptation to over come the subject and start its fatal addiction again). On the other hand if the subject was exercise as soon as possible the subject's body will flush out the toxins quicker and get the body back to a healthier state quicker, however will be seen as more of a strain on the body) as with all exercise build up slowly ( previously heavy smokers should start of with either a long walk or a shorter brisker walk and gradually work up from there. it will take time and effort. so please don't fool your self into thinking that there is a quick miracle fix because there isn't one other that will power and effort.
