E-liquids (aka e-Juice or Vape Juice) are fluids that are used in e-cigarettes and vaporizers. They can come in many different flavors, come with or without nicotine, and you can find them with VG, PG or variations of both.
There is no right e-liquid, and it depends primarily on what the user wants based on their preferences.
Experiment with different e-liquids until you find the one that is perfect for you. To help you decide, check out my best e-liquids page.
I hope you enjoy our little scientific journey on what e-liquids are, how they are made, and what you can expect from certain brands of e-liquids. 😉
