Sapphire, good question and buy only directly from well known vendors.
You are smart to want to know what you're putting into your lungs and body!
Considering that the majority of maker's do not use independent third party testing
there is no way to tell what's in it. They could be putting anything in the juice.
I would wait until strict FDA regulations guaranteeing purity are in place before
buying any juice.

Gosh mike, can you be a little more subtle when you troll?
I find it funny that vapers who care what they put into their lungs still seem to generate a certain amount of ridicule and sarcasm on this board....
.......it was worse years ago before some vape-friendly researchers confirmed that some eliquids represent avoidable risks. Back then, you were just called an ANTZ on the side of the FDA.
