hi,I have smoked poppers for about 2 years now.
A popper is when you take a little rip of tobacco about 1-2 cm and put it in a metal shaft and put a bit of weed on top and smoke it through a water bong.
I also smoke maybe 5 cigarettes a day. for the last 2 years ive been doing this and sometimes i cough up some dark brown in my phlegm, I am just curious how bad this is effecting my lungs as it is unfiltered tobacco that i am smoking, the water barely filters, am i at big risk of getting lung cancer after 2 years ?
