To give an easy to understand reason why this is a bad idea...oil is not water soluable, so it will stick to your lungs and your body will have a tough time getting that stuff out of there (kinda like cigarette tar). Our body simply runs on water as solvent.
All proper
e-liquids are water soluable, so alot easier for the body to "clean them up". There is a reason why we use what we use.
Also, dont mistake the word "chemical" as something bad per se. Water is a chemical, too.
I just googled this stuff, and they seem very eager to tell people its NOT an E-Cig. Look, I'm sorry, but if you heat VG to produce a flavored vapor, its the same principle, no matter what you call it.
