What is the tobacco smell of someone who has just smoked outside and comes in? And is that smell carcinogenic?

Answer

It concerns (harmful) combustion products of tobacco that have lodged in the lungs of smokers. These are stubborn substances that contaminate the inside of the trachea and lungs and stick to it (and cause damage!) for a long time. Even hours after smoking, the smoker’s breath still stinks, demonstrable proof that those harmful products act on the sensitive lung tissue for a long time. Just think of clothing that also smells very long after being in a smoking environment. The lungs of smokers come into contact with the cigarette smoke much more and more directly, and unfortunately we cannot wash our lungs out. The lung structure is very ingeniously put together and the lungs are wonderful, but sensitive organs. It’s a shame that some people want to destroy these organs in such a way.

I would by no means suggest that the smokers still release carcinogenic substances after their cigarette. Most of the carcinogens remained in their lungs and were already absorbed by their bodies. It would go a bit far if we stopped letting smokers in, wouldn’t it? There is no reason for that. Smokers are usually in control of their health problem, literally and figuratively.
