I'm pretty curious about this as well. I have my doubts, since you would have to get the extract's particulates super small, make sure it isn't gummy, and suspend it in something that vapes. I think it would mainly be work that you would need a lab for.
Incidentally, someone on another forum mentioned he tried using an orange flavoring (for food) to make
eliquid and ended up getting a mouthful of citric acid, which he obviously didn't like too much (meaning it burned the .... out of him). Trial and error I suppose, no pain no gain.
