Tobacco : Tobacco contains a number of toxins that paralyse the cilia (motile whiplike hairs) that remove debris, mucus and bacteria from our respiratory tract. When you stop smoking, the cilia become reactivated and are now working double time to try to remove all of the horrible junk that has collected. Please ensure that you are drinking copious amounts to water. This way the secretions will be moister and easier for the cilia to move out. Take care.

Yes: Cigarette smoke stops the hair cells lining your bronchial passages from working, and when you stop smoking they begin to work again and move up all the mucus and crud in the mucus that smoking has put there. This can increase cough and production of dark phlegm but is a sign your lungs are starting to heal. It lasts for several weeks, but eventually improves. Congrats on quitting. Stay quit!
