And because you asked for my medical degree...I think this one trumps all medical degrees...

I can find all kinds of biased sources seeking federal funding as well. If you'll go back and read what I wrote, you'll see that I didn't say I don't think there are health problems related to second hand smoke and I'm still not a smoker, I just don't buy into the second hand smoke lung cancer argument. There is no real way to either conclusively support or deny any concrete facts regarding it, but it's a big scape goat for the medically inexplicable.
Been there with another condition and insurance companies don't pay claims with an "unknown" diaganosis/cause, so they gotta call it someting and blame it on something. You've been in a bar/restaurant where people were smoking??? Must be the cause. :notam:
The ironic thing is, people who smoke who throw their butts in the lake/river/ocean, or even out their car windows piss me off as much as the next guy. You want to burn it, deal with the residuals. I just don't buy the 2nd hand smoke lung cancer relationship.
