I know a guy who works for a gun manufacturer and he says the synthetic gum base is made on the same line that car tire rubber is made on (they clean it between runs of course).

Zyns are pretty clean as far as ingredients go but it is a plastic pouch, and they do contain artificial sweeteners.

I found NicNac Naturals (nicnac.com) which is sold out of the UK and it’s a fully dissolving mint, no plastic or non-natural ingredients involved
