A lot less isn't a number. You going to provide me with a number, or you just going to keep blabbering on about how its not 17%?
Okay, here's the real math, 20% of 6 billion (estimated population level) is 1.2 billion, 600 million people die per year from tobacco only, then you have to add in the 10% that die from various natural causes each year, that's another 600 million. Plus the roughly 5% that die from accidental death, that's another 300 million. The current number in the population that smokes is roughly 20% ... if 85% of the smokers died each year, there would be none of us left, not to mention that you are talking about 2 billion people dying each year total ... add up how long this would have lasted ... there is no way, adding in the chances of failed births because of cigarettes, that our population would have survived more than 5 years ... it's impossible. Not to mention that the smoking population may last 2 years at that rate. A real number, .17% would be believable. But even then, lung cancer and respiratory illnesses are caused by chemicals that are extremely common now, thanks to cars, factories, and other such pollutants, so there is no way to know which such deaths were from smoking and which were from air pollution. Then, now assuming you actually read all the posts you respond to, factor in the fact that there is no medical or scientific proof that simply being near a smoker while they are smoking will increase your risk for anything, it's all purely circumstantial evidence for second hand smoke. Now remember, the first anti-smoking ads contained the little fact that car exhaust contains the same cancer causing chemicals, but also remember that cars put out tons of this a year, even the most addicted chain smoker might put out one ton in a year, far less than a single care. Now, if you are still with me, remember that factories put out millions of tons of this same shit that supposedly causes lung cancer, that's a lot, not nearly as much as the total for automobiles, but it's a lot. The only way to avoid these chemicals is to remain in a completely filtered environment your entire life.
Now, with all the facts and science out of the way, it's simply impossible, period.
