No: After someone stops smoking there will be a period of weeks of increase sputum production due to recovery of the function of your airways. After six to eight weeks you should no longer have a productive cough/smokers cough. Black sputum can be from certain bacterial/fungal infections ad you should let our healthcare provider know.

Even more so: What your lungs are doing are cleaning themselves out. The black stuff is what was down there! now, your little hair cells and airways have recovered from being smoked on constantly and are working, bringing up the accumulated mucus and assorted crap. It can go on for weeks, and rarely longer. Stick with it and congrats on a great choice! don't falter, have a support system, stick with it.

Phlegm: First: congratulation on quitting smoking! now, a decrease in mucus production could be related to the overall improved environment in your lungs now that they don't have to cope with the stress of smoking. None the less, former smokers should pay close attention to their respiratory tracts and report any real changes to their primary doctor in addition to getting routine exams. Good luck!
