Bootleg, I think that genetics might have something to do with it but genetics has a lot to do with cancer in the first place. The problem is that, while the people who do not want you to smoke are not lying, they are putting forth information that, speaking philosophically, "does not follow". Saying that 30,000 (I just made up the number) people die of tobacco related illness a year, is simply built from an illogical argument. The premises might be true, the conclusion might be true (though I highly doubt it), but the conclusion is arrived at illogically. A logical conclusion would be 30,000 people that die of a certain illness every year - an illness that many who have never smoked also die from every year - have smoked. The fact that very many people that have never smoked, or have merely tried smoking, die from the same thing that tobacco is supposed to cause makes their argument just plain stupid.
