Black Mucus; The Causes


The main cause of black mucus can be just the inhalation of dirt, dust, or any real dark black pollutants or chemicals. When you in hale dust that is dark in pigment and it gets trapped in the lung;s air sacs, the lungs expel it to stay healthy. This means that you cough, sneeze, or hack up black mucus as a great result.

Fungal infections

Infections that are caught from all different types of bacteria can also cause black mucus. Sinus and respiratory infections instigated by various fungi can destroy some essential tissues present in the lungs. Also diabetics can suffer from Mucormycosis a condition where it causes black mucus to be formed. Additionally, other more serious infections and conditions that have the symptom of black mucus include cancer, COPD, and emphysema.


Nicotine inhaled from smoking tobacco products is often associated with a discoloration of phlegm and mucus that appears, brown, gray, or black. Chemicals and toxins contained in cigarettes irritate the lining of the lungs and initiate production of excess mucus that expels the tars. Look out for bloody mucus, or mucus that is persistently black.

Environmental pollutants
