These article always say the “smoke has passed through the lungs”. Some of it has but the rest of it or maybe most of it, is coming right off the burning end of the cigarette. It is the same smoke that smokers crave and a huge majority of us hate it. Why should we have to breathe it? I can’t stop breathing because they want to smoke. Take it home and smoke it.
The problem is that these aholes will eventually ban smoking in your home if you have kids in the house.
Don't go where the smokers are.
Problem solved.
