Hi Roman,
I'm a smoker myself (20 - 25 /day) and am not trying to defend the tobacco producing companies in any way, but is that a statement of actual fact?
I could be wrong, (wouldn't be the first time) but haven't the tobacco producing companies set aside a substantial amount of money, as insurance, in order to cater for potential future suits where it is irrefutible that smoking tobacco has caused particular ailments, such as cancer?
Thus far, IIRC, there is no definitive link and the tobacco industry continues to sit on it's money, since no-one has come forward with an indisputable claim.
With that aside, if anyone chooses to give up something, be it smoking, drinking (that's another on my list) or whatever, I'd lend my full support.
Regards.
