Hi there, I've been smoking weed for about 6 years, cigarettes for about 4. For the last 1.5-2 years I have been smoking nothing but bong + cigarettes, and every popper I take consists of about a .3 of weed and 1/3 of a cigerette (I am disappointed unless I fall over with a headrush). I cough up phlegm all day long, most of which has black in it, and in the morning I cough up a fucking hockeypuck worth of black into the sink. Sorry for the details but it is so thick and so big i can' even run it down the drain without using something to push it down lol. Is this just black from the bong hits I take? I'm 20 years old, I understand that black can be tar, but can there be this much? At my age? I don't have an uncontrllable cough, in fact the only time i even cough is to shoot up the stuff into my mouth. Sorry for being gross, but do I need to worry? WHUZ GOIN ON!?
