Honestly, the cigarettes are probably worse for you than the weed. Coughing c**p out of your lungs like that's not a good thing. Seriously - you're young. Cut out the ciggies and give your lungs a chance to clear up before they stop developing.
I'll let someone with more medical knowledge advise about the black stuff.
