You would have to go back to the 1940s to get to where they weren't adding the harmful things.tell that to my dead pappaw who quit smoking in 1975 ish and still died of COPD/emphysema at age 81???? my daddy is 71 and just quit in last few years and is at same level of COPD as was pappaw was at his age!
On a side note, as a current non smoker (probably at least 30 years), I can tell you that kissing a smoker tastes pretty much like licking an ash tray.
