I spit out black stuff, is it tar?
today I went to spit out what I coughed up.. I opened my mouth.. looked on my tongue and saw black slime attached to my saliva. .. it wasnt a lot but it was enough to notice. I have bad allergies and I have asthma.. which has been flaring up more lately due to spring allergies. Im 19, I don't smoke but my mother does... is the blackness from inhaling my mothers smoke? or is it something else?
