In brief: 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.
