1) The only benefits are coming from Nicotine, which is a central nervous system stimulant. Adderall, Caffeine, Meth, etc will give you these slight benefits to varying degrees as well.
2) Nicotine tolerance levels increase fairly quickly and usually don't return to normal very quickly or at all. Ex smokers that smoke again will find themselves very rapidly right where they left off due to a lack of tolerance normalization.
3) Any potential "cognition and productivity" benefits of smoking can be ignored when you factor in the lower blood flow literally thins out your cortex over time.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4430302/4) Smoking does have a massive part to play in your cardiovascular ability, to deny this would be completely braindead so don't bother.
So what does smoking give you? Slight stimulant effect with a quick and long lasting tolerance build up that could just as easily be replaced by coffee. Except by smoking you also give yourself literal brain damage in the form of cortex thinning, and physically handicap yourself through cardiovascular damage. Even assuming smoking has 0 correlation with cancer, it would still be fucking retarded.
