Lung diseases

Coughing up black stuff



I have been coughing up black stuff. This occurs everyday. I have had drug use in my past and wondering if this is the cause. The last time I used was like 6 months ago, but I am still coughing this stuff up.

Please help.


I am not sure what this represents – it could be dried blood (it tends to look dark red to blackish if it is sitting for a long time). It could also be some sort of contaminant – did you inhale the drugs (eg., crack), as you can have particulates deposited in your airway. Are you around anything like grinding rock or coal?

You should see someone and get a chest x-ray and determine the source of the problem and define the black material you are coughing up.
