If smoking is really that bad for you, why is it that despite the nearly 9 decades of anti-tobacco research and the government's non-stop assault on the users, not a single scientist has been able to prove that tobacco causes cancer or COPD in even a single animal or randomized epidemiological study, thus forcing the entire consensus to rely on self-selected epidemiological data without controls for extraneous factors (and even then of course the evidence is weak at best, compare Japanese or Greek lung cancer or COPD rates to the very anti-smoking USA). Curious thing.
