You've got me there; lung cancer and heart disease do make for irrefutable excuses to cut out.
Anyway, my complaint was more about the smell of smoke and how it lingers on clothes and in the air for nonsmokers. It wasn't mentioned in-post, but I'm constantly hearing wet coughs as well, which is both disruptive to my workflow and is just gross (especially in a post-pandemic work environment where people refuse to even cover their mouths or use sanitizer anymore).
