I don't trust PG. It makes everything pass into your system more easily when you ingest it, if I am to understand correctly. I dissolve my benzos into 40% alcohol.. I don't ever eat food containing PG, and just because something is used in food doesn't make it safe for long term use in my opinion. I don't eat almost anything in your average supermarket because of the nasties in it. Depends how you live your life, whether or not to be concerned about pg. The research is out there if you google it. It's probably not the biggest deal but I don't think it's "healthy".
