Does smoking really cause lung cancer?

I’t a proven fact that it is.. it’s commen sense. jazlovestoskate seems to know her stuff. theoutcast and smokersmokersmokersmokersmokersm are dumbf*cks

yes, its already been proved that it can cause lung cancer and it doesnt take long either, depending on how much you smoke not only does it contribute to lung cancer but many, many other things mainly decreasing your life span and prematurely aging your body and skin

Smoking doesn’t cause cancer. The commercials only say it does so people sponsor them and then get more money. Like smoker said, smoke up. You won’t die.

yes smoking will cause cancer in a person but not always smoking will not always cause a person to die either. A person who smokes is 75% more likely to get cancer than a person that doesn’t smoke. Smoking not always causes cancer but it can cause asmua, strokes and more. Have you ever seen an old person pulling an oxygen tank around? Smoke will eventually destroy the lungs and the lungs will never heal like a cut on your hand will heal. A person that doesn’t smoke but lives with a person that does is also capable of getting cancer from what they call 2nd hand smoke. So go ask any hospital and ask to look at the lungs of a person that smoked and of the lungs of a person that didn’t. Why do firefighters wear masks over their mouths when they enter a smokey house? Smoke blocks oxygen to the lungs talk to any doctor.

nope. smoke up. it’s just a myth man.
