The reason active tobacco smoking could be such a terrible killer while passive smoke may cause no deaths lies in the dictum "the dose makes the poison." We are constantly bombarded by carcinogens, but in tiny amounts the body usually easily fends them off.
A New England Journal of Medicine study found that even back in 1975 - when having smoke obnoxiously puffed into your face was ubiquitous in restaurants, cocktail lounges, and transportation lounges - the concentration was equal to merely 0.004 cigarettes an hour. That's not quite the same as smoking two packs a day, is it?
But none of this has the least impact on the various federal, state, and city agencies and organizations like the American Lung Association for a very good reason. They already know they're scientifically wrong. The purpose of the passive smoking campaign has never been to protect non-smokers, but rather to cow smokers into giving up the habit.
It's easy to agree with the ultimate goal, but inventing scientific outcomes and shutting down scientific debate as a means is as intolerable as it was when Nazi Germany "proved" the validity of eugenics. |
