>To you and me, we associate smoking with health problems so subconsciously we hate it a lot. We also never feel the "good parts" of smoking so our minds are entirely biased into the negative aspects of it.
No one feels the good parts of smoking before they start and most people find the smell unappealing.
>Meanwhile, a smoker grew up without caring about the health damages and they consider it fine to smoke and the cost is acceptable for the "good" a cigarette can provide.
I'm not saying you're alluding to this but just to be clear, this is who a smoker develops into, the person was not some sort of pre-smoker who's dispositioned to like things that are bad for their health which would allow them to tolerate the smell. The tolerance is built.
