[Just another Joe]

But, hey, I realize that like the FACTS about smoking and second hand smoke--

THE FACTS about what I say on this thread really don't matter.

Once again, what facts?

[Quix]

The study starting this thread is one.

There are sufficient quality ones in the long list of many provided.

There's more than sufficient evidence to have a fair comparison of well derrived researched facts.

I have no need to get into that level of tedium, thanks anyway.
