So it's tedium saving the lungs of unborn, newborn, and young folk that you keep referring to yourself as caring so much about?
If you can't give the studies, you ain't even read the abstracts or synopsis and don't know what you're talking about.
I can go through the entire 708 studies the other poster talked about and on ETS it will come out about 80% against there being harm and 20% for.
You can't even look up any that support your stance because it's tedious.
Bah
LOL.
