So what I'm reading is that there's no clear evidence for tobacco causing cancer per your scientific standards, but is there clear evidence confirming that it doesn't? And if there isn't, would it not be wise to assume that in the absence of information, a strong correlation would be sufficient between the two to make the claim that one can cause the other (and understand that no one's saying it's the sole cause of all cancers by any means?)
idk, man, I'm not going study searching because it ultimately doesn't matter to me. I smoke cigarettes and, most likely, they'll help snuff my life out sooner than if I had never picked up the habit-- and yeah, cancer risk is most definitely increased. This is one of those fact of life things to me that I find it hard for others to disregard as false. When stuff like that happens I just can't help but try to see that other perspective, or at least have it explained to me.
[EDIT: god damnit tater, you've piqued my fucking interest. I was about to smoke some weed and play fucking Diablo 2 but now I'm drawn to Google and I'm about to read through this bullshit:
