'Newly detected air pollutant mimics damaging effects of cigarette smoke'

A previously unrecognized group of air pollutants could have effects remarkably similar to harmful substances found in tobacco smoke, Louisiana scientists are reporting in a study scheduled for presentation today at the 236th National Meeting of the American Chemical Society.

Inhaling those pollutants exposes the average person up to 300 times more free radicals daily than from smoking one cigarette, they added.

Smokers likely get a double dose of PFRs every time they light up, Dellinger said, since tobacco smoke also contains these molecules. In the five minutes it takes a typical smoker to finish a cigarette, he or she will breathe in an equal number of PFRs from the air and the smoke itself, likely compounding the damaging effects.

“Inhaling those pollutants exposes the average person up to 300 times more free radicals daily than from smoking one cigarette, they added.”
……………………
Seems to me that in Logic,for A=B to be true,it must also be true that B=A.

Thus,if their statement is A=B;then, it MUST also be true that B=A,or ” smoking one cigarette exposes the smoker to 1/300th the free radical pollutants the smoker would normally inhale daily anyway.”

Clearly, a smoker would have to smoke 300 cigarettes(15 packs) per day to equal the nonsmokers exposure to the free radical pollutants.

They also state this:”Smokers likely get a double dose of PFRs every time they light up, Dellinger said, since tobacco smoke also contains these molecules. In the five minutes it takes a typical smoker to finish a cigarette, he or she will breathe in an equal number of PFRs from the air and the smoke itself, likely compounding the damaging effects. ”

This is ‘SCARE-MONGERING’ of the worst sort!!

While the statement is technically true, the total free radicals added by smoking a pack/day is only an extra 6.7% of the free radicals inhaled by non-smokers.

[[[Clearly, a smoker would have to smoke 300 cigarettes(15 packs) per day to equal the nonsmokers exposure to the free radical pollutants. 20 divided by 300 = .06666666 = 6.7%]]]

Antis will jump on this anyway, to prove that SHS causes extra harm.

“Clearly, a smoker would have to smoke 300 cigarettes(15 packs) per day to equal the nonsmokers exposure to the free radical pollutants.”
………………………….
Since the typical non-smokers SHS exposure is only 1/100th the smoke exposure of a smoker:

A non-smoker would have to be exposed to the SHS from 30,000 cigarettes per day to equal the nonsmokers exposure to the free radical pollutants they daily breathe.

This is about 21 per minute.

"The discovery could help explain the long-standing medical mystery of why non-smokers develop tobacco-related diseases like lung cancer..."

"'Free radicals from tobacco smoke have long been suspected of having extremely harmful effects on the body,' Dellinger said."

If this is really a recent discovery, does anyone else think that too much time and money has been spent on anti-smoking studies?
