What is Vape Juice/E-Liquid?

Vape juice goes by a few other names like e-liquid or e-juice. All of these terms are used interchangeably and mean the same thing in that they are used in vape devices as an alternative to smoking cigarettes. Vape juice is a mixture of water, food grade flavoring, nicotine (or none if preferred), propylene glycol, and vegetable glycerin.

Vegetable Glycerin (VG)

VG is a natural substance that is processed from vegetable oil, but is not actually an oil. “In fact it’s an alcohol, which makes it safe to inhale.” VG is used in a variety of products like pharmaceuticals, cosmetics, and food. “Scientists have studied it for years, and it’s never been linked to any health problems.” VG is a thick substance which causes large cloud production upon exhalation. When vape juices are described as smooth, it is in reference to the VG content. The throat hit is significantly less intense than PG. VG is colorless and has no smell but alters vape juice flavors and causes them to be sweeter.

Propylene Glycol (PG)

PG is the other main ingredient in vape juice. “PG is a colorless and odorless petroleum byproduct.” PG can help enhance the flavor of your vape juice and leave a strong taste in the back of your throat, which is considered a throat hit which “mimic[s] the sensation of smoking tobacco products.” PG is less dense than VG and doesn’t alter the flavor of your vape juice whatsoever.


Most vape juices contain nicotine. However there are multiple companies who make 0mg vape juices for people who are getting close to quitting completely, or just vape for the flavor. Having nicotine in vape juice is what makes vaping such a great smoking cessation option for ex-smokers. Nicotine by itself, while addictive, is not necessarily harmful. Nicotine can be poisonous if consumed in enormous quantities, but smokers and vapers alike generally know their limits. Nicotine levels can range from 0mg all the way up to 50mg depending on your preference. The higher nicotine levels ranging from about 25-50mg are usually meant for ex-smokers who have an increased tolerance and are typically salt nicotine vape juices meant to be used with a MTL vape device and coils.


One of the most intriguing aspects of vaping is all of the wonderful flavors to choose from! The most popular food flavorings are vanillin (a vanilla flavor), linalool (an herbal flavor), ethyl maltol (a sweet, bakery-like flavor), acetyl pyrazine (a graham cracker-like flavor), and malic acid (a sour, fruity flavor). Flavor makes up about 10% of the vape juice mixture, but is the food grade additive that most vape enthusiasts crave. Of course there are multiple vape juices that come with no flavor, if you’re into that sort of thing!
