I don't know, I quit smoking in 2014. I smoked on and off since age 13. What I do know is cigarettes use to smell like tobacco, sometime in the 90's mid to late, the smell changed from tobaccoish to chemicalish. I needed to smoke more all of a sudden and never smoked more than 1/2 a pack a day before that. They have been trying to kill us for generations I think…
Could be but the smell was worse than nicotine, I vape now and use low nic mg. Sometimes I can smell nic burning when coils get burnt or old, totally diff smell…in the cigarettes now. In fact I can't stand the smell of cigarettes now. But I like the smell of pipe tobacco. Something more in them I would wager.
