And the flavorings used are designed to be ingested as they are designed to be used in food and beverages.
Kind of curious about this in a very low key minor way. Had a nurse suggest, "the oils get in your lungs oh yuck, who knows what that stuff does to you."
Flavorings as far as I've seen normally are GRAS for in food you ingest. Sure, I got that. My question then is are they safe for your lungs? My thought is that ingesting them leads them into your bloodstream by your stomach. If you vape and get the flavoring vapor in your lungs, it goes into your bloodstream like the nicotine, absorbed by your lungs.
Is there some magical difference where by these GRAS flavorings leave residual oil/s in your lungs but not your stomach? Are there even oil/s in the flavorings? I know that some are oils, yes. But I don't think any of the oil/s get
stuck in your lungs as it seems they too would get absorbed into the bloodstream.
I stay away from cream, custard type of juices and any popcorn flavors. These do worry me a little bit as some vendors might not seek out safer flavorings to use in creating them. I also vape unflavored juice. As far as I know from reading PG and VG are both degrees of inert substances, alcohols that if not absorbed into the body to pass through safely, get evaporated.
All in I think the nurse in particular attempts using scare tactics. To a degree my reading says that is likely, knowing people also says that. Hm, just some thought for food.
