I usually didnt smoke everyday up until a few months ago and ever since then when I smoke I find myself coughing a whole lot more than I usually do. I can understand how a new smokers lungs could be damaged by the smoke but ive been smoking for atleast 3 years. For example. I can smoke a bowl just fine hitting it easy just to start my buzz off nice..But when the next one comes around I start coughing alot and I have to spit alot and it feels like theres alot of like mucus or snot or something like stuck in my throat and it makes me keep coughing but never to the point where I puke. I thought about it for awhile and then came to the conclusion that maybe your lungs collect resin like any smoking device does. Could this be true??? It makes perfect sense and maybe im just not getting enough oxygen to my lungs when I smoke. This ever happen to anyone else? Oh yeah and about 90% of the time me and my friends smoke we are in someones car cheeching it up..You think this might have something to do with it???
