Hey there guys
I'm 23 days into my quit. Since stopping, I've noticed that I sometimes cough-up bits of mucus with flecks of brown in it. I can only describe it as looking like little bits of wheatabix (?) Would I be correct in assuming that it's bits of tar? Also, every once-in-a-while, I've coughed-up small bits of darker (almost black) bits of stuff which looks like little bits of burned nut shell (my God -- perhaps they're little bits of burned lung!)
It's only very small amounts every now and then. Would this be my lungs clearing themselves? Or is it something I should be concerned about? Anyone else had this? I'm a little bit worried if I'm honest.
