A smoker smell at 30 feets away, clothes, teethes, fingers, breath, when wife or son who are non-smokers come back home after a meeting where smokers were, I can smell that odour from very far ! All non smokers have the same sensitivity to that specific smoke odour, so different from fire wood, so different from BBQ.
Cigarettes smell a mix of grass smoke, amoniac who is used to make you addicted, cupper, and chemistries !
Stopped smoking 36 years ago, and I was close from 50 cigarettes a day ! It takes me 2 years to stop completely, no issue from stopping, the weightscale added 20 Lbs and I reached 150 Lbs for 5 Feets 5" (1.75 meter)
Hide your smoke addiction to the doctor is funny, you can't hide it to cancer ! You voluntary for !
For your life stop smoking !
