Thanks for posting your query.

Commonly the black spots in spit are due to the carbon particles and this is due to the active or passive smoking. This is common in smokers & when we breath in polluted air. However normally there is no change in the color of the sputum after spitting.

I will suggest getting a microscopic examination of the sputum done to find out the cause of these black spots. I also suggest getting a chest X-ray done to rule out any lung cause like any infection, inflammation or any benign or malignant growth of the lung.

Sputum examination and chest x-ray will also clarify whether there is any hemoptysis which is the expectoration (coughing up) of blood or of blood-stained sputum from the bronchi, larynx, trachea, or lungs.

Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
