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.

Depends: Are you a regular cigarette smoker? If your use of Marijuana was heavy, then your lungs may have some gunk to clean out. If this goes on for more than a week or so, you may need your family doc to evaluate your lungs.
