"Our results are potentially significant because aminoketone is the direct precursor to the tobacco-specific lung carcinogen NNK, which is believed to play a significant role as a cause of lung cancer in smokers"
They don't know if NNK is an ACTUAL cause of lung cancer.
Their 'experiments' are based on the assumption that it is.
Proves nothing.
Nobody knows what actually causes many cancers, possibly viruses, bacteria or chemical exposure, but we can certainly gather evidence to come to an idea, in fact if 50% of lung cancer patients were smokers, while only 20% of the population smokes, is that evidence to you? The truth is studies like this are important to help discover cures or to prevent cancer from even occuring. I realize many freepers are tepid against these things, calling the studies flawed, funded by anti-smoking nazis etc..but to say that smoking is safe or whatever is simple silliness, like I said I am a smoker, who comes from a smoker who died of lung cancer, I know the difference my body has shown from before I smoked to what it is now, there is a difference. Sure some people are genetically predisposed to cancer, but sometimes that predisposal needs a catalyst and smoking for some is that catalyst.
Apparently there is a drug out there to treat depression, Bupropion, that is a form of aminoketone. Google it up.
Proves nothing.

Actually, to me,
DENIAL OF HARD FACT SCIENCE FINDINGS AND PRINCIPLES
PROVES NOTHING.
