I've been told that two main ingredients are propylene glycol and vegetable glycerin. In a variety of places, there has been a lot of support for non-propylene glycol or e-liquids that are MOSTLY vegetable glycerin are much smoother. Since I've been sick like crazy, and my "new map tank" has been doing nothing but drip all of my stuff out.. I need to buy some more and I want to go with a real clean e-liquid. Any recomendations (and please make sure you know about it.. the propylene glycol thing is really important).
