Just a quick question. . .

StonerBill, you said their are carcinogens, but they arent' carcinogenic. I had an arguement with a bunch of my frineds, and i was pretty confident their werent carcinogens in pot. But, now i hear theat there are, so, does this mean, they are their, but they don't cause cancer?? Cuz i heard from my teacher all carcinogens cause cancer, thats how they get the title.
