The stuff from your lungs is grayish or black, right? Not brownish black or having a few flecks of red? If it were bleeding, I'd expect to see a bit of fresh blood now and then! You are smoking! Smoke particles are black. Smoke coats the lungs, some sticks and the lungs try to clean themselves.

Get a vaporizer (Vapor brothers are good), use it exclusively, and in 2 weeks I'm willing to bet the problem will be gone! (no smoke, no black!)

On the slim chance that it doesn't get gone after 2 weeks of vaping,(or if you are seeing any red flecks) I'd get me to a doctor!
