*Thought*Getting less THC?

So just smoking playing some Black Ops and started thinking.. after a long time of smoking your lungs start getting gunked up right? well over a period of time wouldn't it get to the point where your not absorbing all the THC in the smoke because the smoke isnt even getting a clear passage way to enter the blood stream or whatever? Like maybe if everyone started out with a vaporizer and there lungs didnt gunk up there tolerance would also raise slower? idk about that last part but just a thought lol.

ripping some Herijuana and 51/50

that has crossed my mind. i don't think the inside of the lungs is like a bong though. a bong stays dirty until it's cleaned by someone. the lungs are sort of self-cleaning to a point. i think it's more likely that the years of smoking just plain 'ol wear out the lungs so they don't work like they should. lungs working at 80% capacity probably don't do such a hot job absorbing and expelling, so i do suppose this could eventually lead to not getting the full effect from the herb.

i get this and i know where you're coming from. i also smoke cigarettes and when i was smoking 10-12 blunts a day i was at a point where i couldn't breathe properly and when i blow out the smoke, it wasn't like before. you can tell i'm blowing out less smoke. that's when i started utilizing my bong and jogging in the morning and at night. i started coughing out NASTY shit. eventually i got back to normal..

but im sorta like that now again
