In some cases viruses, infections, and conditions can cause healthy mucus that is considered normal to become colored, grey, brown, green, yellow, and even in worst cases cause black mucus.

Black mucus can be caused by many things that can be temporary or by factors that merit a further look which could be serious..

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

Pollutants that you can breathe in from the environment such as cleaners, paints, and other types can cause the respiratory system to generate mucus that is black. Coal miners are often very familiar with coughing up black mucus as the coal is thick and tarry and as it is inhaled it coats the nasal passages and the lungs air sacs. The best way to prevent and remedy this cause of black mucus is to wear a respirator mask when exposed to this type of materials that are chemically unsafe to inhale.
