Neither do I, and I doubt anyone else seriously believes it. Notice that nobody has published poll results all over the place showing large majorities believing the "secondhand smoke" propaganda. Oh, the polls have been done, and if they'd showed majorities, they'd have been blastfaxed all over creation.
It's just so transparently operational lying, making stuff up and then persuading themselves that they halfway believe it, as justification for the obviously high-handed tactics they want to use next on cigarette and cigar smokers.
