Smoking or no smkoing

Hello here is one topic which came into my mind last night observing few smokers.

Is it the relaxation one gets during the smoking in a group or alone, which leads to a unique personality of a smoker?

I mean lets say that we stand or sit in a group or alone for a few minutes doing nothing and just relax, will it lead to same addiction/relaxation/improved efficiency which one gets when one smokes alone or in a group.

Lets say you were working very hard and moving all day long from one place to another on foot and than you started to miss few things later and you just paused for a few minutes and sat down and relaxed, will it lead to same effects if one pauses and smokes for a few minutes? Which person achieves more relaxation and thus able to continue more efficiently for the remaining day?
