You mean like the Kinsey study?
I’m not denying anything. I just don’t trust the doctors. It took years and years to convince them to wash their hands. They are just as arrogant and imperialistic today.
You seem to have an issue with your family doctor washing his hands or not and translating that into research scientists being biased or foolish.
Whether your practicing doctor is arrogant or not has nothing to do with the realities that smoking causes cancer, and yes like it or not it does.. in everyone nope, but in a hell of a lot. They have even isolated the exact mechanism which it interferes with cell division to start the cancers in the first place.
You smoke for 25 years years, then stop and 3 years later are diagnosed with cancer, then want to blame it not on the fact that you abused your body for 25 years filling it with harmful and cancer causing chemicals, but on the fact 3 years ago you quit??
Please, this is nonsense. The root cause of these cancers in this study, is still the abuse that the smokers put their bodies through for decades. Even if you buy all the suppositions of this study.
