They are either liars, or they are not - which is it??????
I think PM is probably providing all this info as damage control rather than out of the tender goodness of their ever so honest hearts. As to whether or not they are liars, I think plenty of documentation has been brought to light that for years PM and other tobacco companies were more aware of the health risks associated with smoking than they had claimed and also tried to conceal or misrepresent those health risks. Does that mean they are incapable of publishing truthful information? No, I would say not. Even a congenital liar like clinton could occasionally tell the truth when it was in his best interest to do so.
I merely posted the PM website info because I found it recently (a very impressive, rather expensive brochure published by PM with weblinks, indexes, etc.) lying around at my office. I looked at it, expecting it to have a lot of double-speak, downplaying risks, criticizing research, etc. but instead found that it seemed to be a straightforward presentation of factual data.
