I've read a few studies by respected people/organisations and some are breathtaking. For example I think it was ASH (Action on Smoking & Health) who did a survey on the effects of passive smoking years ago and their conclusions were that it was virtually harmless. They have "buried" that survey and now refuse to answer any questions on it. Or how about the fact that although Native American Indians have one of the highest rates of smoking, they also have one of the lowest rates of lung cancer. Similarly, Chinese women have one of the lowest rates of smokers, but one of the highest lung cancer rates. Maybe smoking's not as bad as we're led to believe, I'm sure we all know an old uncle so-and-so who's smoked since he was 12 and, although he has a bad cough, he's still going at 85.
