However, because researchers have found precancerous changes in cells taken from the lungs of heavy marijuana smokers, the possibility of lung cancer from marijuana cannot be ruled out.





Kremit - read that again. I don't think anybody's claiming it doesn't damage tissue.

Unlike heavy tobacco smokers, heavy marijuana smokers exhibit no obstruction of the lung's small airway. That indicates that people will not develop emphysema from smoking marijuana.





I think that's a pretty bogus assumption. Emphysema isn't caused by a physical obstruction (although it's technically called a chronic obstruction pulmonary disease), it's caused by reduced elasticity (and hence recoil) of the lung tissue. Smoke (and sometimes genetic disorders) damage the tissue so it can't recoil and expell the used air.

Ever seen somebody with a barrel chest who's exhaling short and shallow breaths? That's emphysema - their lungs can't expel the air that it's used cause the tissue doesn't recoil anymore.

Rock on, Mike. I think there's no better person to talk to about drugs than some who's frank, truthful, and isn't out to prove something.
