If only that were true. A simple example is cervical cancer. More than 95% of cervical cancer is caused by a sexually transmitted virus, HPV. Yet, the agenda-driven still claim smoking is the number 1 cause of cervical cancer. Instead of seaking a cure, or education on prevention, they continue to blame smoking for something they have already proven is NOT caused by smoking.
I don't claim smoking is a harmless habit, let alone a healthy one, but it is sure as heck not the cause of nearly every ailment known to mankind as claimed by the anti-smoker paid professionals.
Ummm how can it not be true and then you go on to state numbers, that maybe came from a study? Perhaps that study was important in helping to find a vaccine for certain HPV's? You countered your own argument with what you were arguing about there.
