A member asked:

Hello doctor,i quit smoking 5 months ago and i used to smoke half a pack a day for 4 years and till now i have not seen any tar yet.when do they come?

A doctor has provided 1 answer

Stopped smokin: you might not have the dark tracheal secretions some smokers cough up. If you have not had this in the past, you probably will not get it. Maybe you have not caused the special cells that line the respiratory tract to change into the other cells that cause mucus thickening and pooling which you see in long term smokers. Good luck and feel better.
