I don't see that it would HARM you necessarily but like these flavors are made for vaping you might have better luck with concentrates actually designed for um, flavoring food although I suppose a little PG never hurt anyone. Only... Yukk.
Sorry. LOL I guess some of my flavors smell better than others. but none would I probably jello shot with.
