I didn't even read the damn article but here are my thoughts:

THC may be an anti-cancer agent but I do know that smoking anything is not good for you. you hold in your hits till you cought ur brains out and ur eyes tear. not one of you stupid fucks think that its not causing any damage to your lungs.. consider how small your alveoli are. why is it that they never linked cannibus smoking a direct link to lung cancer? because most users also smoke tobacco, so they can't conclude its cannibus alone. also, most users stop when they get older and more mature, before signs of respiratory cancer form. its smoke, not oxygen. it damages ur lungs. i have nothing against smoking pot tho, its a great thing, why else would i be on the forums? but don't be misinformed to try and justify your bad habbit. know the facts, then make ur decisions on how to proceed.
