What does your skin,liver,lungs,stomach and intestines have in common?When INHALED?
They are all essentially filters. Granted they are optimized to filter different
things but that doesn't mean they are not capable of filtering out in their
own ways substances not meant for their particular function. There is a reason
we burp you know. Just because something is GRAS for oral or topical use
doesn't automatically exclude it from being inhaled if not used in quantities
only found in industrial settings. Granted there "may" be issues. Then again
there "may" not be issues. I personally have considered the fact that one
is now inhaling "whatever" that is considered grass the least of our concerns.
We have been inhaling them all our lives with no apparent issues over our
lifetimes.(acute sensitivities aside) The scientific evidence seems to bear me
out.
