FDA is an agency built on sound science. I know because I worked there as a bench chemist for 26 years.
SO I am torn about one of the proposed warnings they intend to place on cigarette packs: Second-hand smoke kills, or something to that effect.
Without having seen the studies they must have used to come to this conclusion, it is hard for me to come to a firm belief that this is so much junk science. BUt my inner scientist is SCREAMING that this HAS to be junk science, science with conclusions that are pre-determined for politically correct reasons -- you know, theories like the mythical Global Warming, which advance nobody but global bureaucrats and socialists.
Here is what is wrong with ANY theory of second-hand smoke: The matter of the dilution factor.
FDA scientists are well-accustomed to the idea of diluting. We do it all the time. And we are accustomed to measuring the presence of substances which, if present in trace quantities, are considered safe, but are considered dangerous if they cross particular
threshholds.
And so I come to the issue of smoke from cigarettes -- from primary, and second-hand smoke.
We KNOW that PRIMARY smoke from cigarettes -- that is to say, the smoke that a smoker himselgf inhales when he smokes -- in SOME cases, AND AFTER 30 YEARS OR SO of smoking, MIGHT cause health problems -- cancer, emphysema, etc.
And now comes the dilution factor. "Second-hand smoke" is the smoke that circulates
through the air inside a given room. I am writing this while seated in a SMALL office. The room measure about 8' high x 10' x 10'. THis office holds about 800 cubic feet. Let's say it's 1000 cubic feet.
1 cubic foot = 16 liters, roughly, of volume. So now we can say my office has a volume of about 16,000 liters.
The volumetric capacity of the human lungs is about 1 liter, though an informed doctor could doubtless give a more precise figure.
That means, if I smoke PRIMARY smoke, I am smoking smoke that is about 16,000 times as concentrated as it would be if allowed to circulate freely
through my office.
It is this PRIMARY smoke which in SOME cases, many years away too, will cause health problems.
So, if PRIMARY smoke, which is tens of thousands of times stronger than second-hand smoke, has only THIS level of impact on health, then how likely is it that second-hand smoke can affect health at all?
The answer is, it CAN'T. Second-hand smoke, ON ITS FACT, canNOT have a serious impact on health.
Therefore, as much as I hate to admit it, even the hallowed FDA is on a politically-correct witch-hunt.
