Pipes, Cigars: Safer than Cigarettes

Cigarettes are almost certainly and entirely bad, but why?
I suggest that a part of the reason cigarettes kill is that many of them have polyester filters.
Polyester sometimes feels snug, as many of us know through wearing polyester clothing.
Leave polyester against your skin or body tissue for an extended period of time, it is bound to become irritating.
In addition, when smokers inhale, they also may be inhaling small particles of filter, especially if the cigarettes are old and the polyester is broken up.
Through investigation, it occurs to my thoughts that the irritation that these small polyester particles give to the lungs can cause cancer.  15 or so years before Camel, the company that invented the filter cigarette, began putting polyester filters in their products, lung cancer was virtually unheard of among smokers, but those 15yrs gave just enough time for a link of smoking cigarettes with cancer. 

In addition, there was even the possibility that centenarians had their life expectancy increase if they were a smoker, but that I hypothesize was because they started smoking before polyester filters had been invented.  As filtered cigarettes have become more pervasive, so too has the morbidity of cigarette related products increased.  I suggest it is that the polyester filter that is doing us wrong, while the past ways of smoking, such as unfiltered pipes and cigars are actually safer.
