Just coughed grey phlegm.. was pretty fucking nasty. Must have to do with smoking a 1/4 in a night with a few friends mostly in this 4l gravity bong. According to wikidedia: But it just happened once.. so I doubt there's anything to worry about. Anyways.. fuck phlegm
I've been coughing up so much shit lately after I started smoking heavily a few weeks back...I since stopped last week but I still have a bunch of phlegm I cough up all day long
i cough that shit up sometimes..it's sickening. this is gross, but my friends used to spit phlegm out onto a sidewalk and then compare to see who's was more brown and gross.
^ nah... I've stopped it's been about 4 months.. and even then I only smoked for about 6 months and an average of 3 cigs a day.
