So I always try to cough up the back drip because I don't want it going down my throat and swallow it. Last night I did that as always but it was accompanied by quite a bit of blood. At first I thought it was coming from my teeth but I coughed it up again a couple of times and there always was blood. Did that ever happen to anyone? Should I be worried? I don't know if I just over did it with the snuff. 25g usually last a week for me. I'm using only Viking Brown at the moment. Maybe the snuff is a little harsh?
