Oh, it's definitely from smoking. It's little bits from all the tar that's accumulated in your lungs.
If you cough up a little bit, rest assured that there's a whole lot more in there trying to coat the inside of your lungs. It's not a good thing, but at this point it's kind of just a fact of life for me.
I wouldn't feel concerned enough for a doctor's visit but hey, if you're worried you should get it checked out. A little break for your lungs and a cardio regimen should clear it up in most cases... but if you ever cough up blood, though, you're gonna want to see a doctor ASAP.
