Uh, no! Seriously... no! Although the flavors are based in Propylene Glycol (PG) and PG is used in e-Juice, the concentration of flavoring is much too high to be used as an e-Liquid on its own. Think of it like getting a fountain soda where the syrup and water are mixed as it is dispensed into the cup. There is very little syrup in comparison to water. This is because the syrup is concentrated and is using the larger volume of water to dilute it to the proper strength to taste as it was intended.

If you were to barely press the dispensing arm and fill your cup with syrup, when you drank it you would NOT like it; nobody would. The same goes for concentrated flavorings. In the example above, even if you used 1/4 cup of syrup it would taste similar to what you wanted but not entirely because there is too much syrup in the mixture.

Do-it-yourself (DIY) e-liquid making is the same process. You can use too much flavoring even in your juice and you will know that when you start losing subtle notes of the flavor.
