I would say this has nothing to do whether or not your intelligent ( I know Doctors, Scientists, Shrinks, who all smoked after knowing the facts, ( I worked at a medical center for some months and met all these people who later became my cig break buddies :P ) Im not that scared of cancer either, I figure just breathing in the air now and days will prob cause cancer, not to mention sunlight, foods, ect (of course cigs just speed it up, but who wants to live forever? :P
