Yeah, I saw that Wiki article. My understanding of chemistry is, shall we say, incipient (or you might say "nascent." (ha-ha, subtle joke).
The Wiki Article points out that the new inhalers no longer contain CFC's (Chlorofluorocarbons)as propellants, but instead use HFA's.
I just don't understand what an HFA is and whether it contains Fluoride - or even what the heck it does contain in the way of elements.
Thanks for the info about boron. Going to research it.
