"Low-tar" cigarettes appear at least as irritating as other cigarettes. More than half the irritant is associated with the particulate phase of the smoke, permitting deposition throughout the entire respiratory tract and raising the issue of whether formaldehyde in smoke is associated with bronchial cancer(1). That's ONE of HUNDREDS of carcinogens found in cigarette smoke. quit-smoking-stop.com gmu.edu You have direct evidence of physical causation. And you have statistical studies backing that. And Colby is WRONG when he states no statisticians have examined the data backing the statistical links. And lung cancer is not the greatest risk from smoking.
