...and had anyone tried them?
Yeah, I did notice they were food grade and I was a little concerned confused.Not tried them.
Do they have bad stuff?
No one yet knows what the long term effects of inhaling flavorings designed to be eaten is.
Once they figure that out they will maybe know what the bad stuff is.
As far as I know, all flavorings are.Yeah, I did notice they were food grade and I was a little concerned confused.
Don't confuse an already confused person.As far as I know, all flavorings are.

Yep there are NO flavorings approved for vaping.As far as I know, all flavorings are.
The JF I do have are excellent! Boysenberry is comparable in both flavor and strength to Flavorah. Their biscuit is interchangeable with Inawera. Strawberry sweet is very good, and their yellow cake can be used 1:1 for FW yellow cake, but without the sugar. I've ordered a few more to try, I've been very impressed so far.
