Our Beginner’s Guide to E-juice: What You Should Know

Today, many people are looking for effective ways to quit smoking, and one thing many former smokers swear by is vaping. Personal vaporisers and box mods are becoming more popular because they provide greater customisation. You cannot build a mod without knowing about vape juice and e-liquid—here are things you should keep in mind.

Vape Juice, e-Juice, or e-Liquid: Which is Which?

First of all, e-liquid, vape juice, and e-juice all refer to the same thing. Manufacturers, vape shops, and enthusiasts all use these terms interchangeably. Vape juice is the fluid you put in an electronic cigarette or a vapouriser. 

It is the substance that creates the clouds of smoke—it can contain nicotine, though some solutions are nicotine-free. A vapouriser heats the e-juice and turns it into a vapour that you can inhale—typically, pens heat the liquid, which reaches temperatures between 93 to 204 degrees Celsius.

What Does Vape Juice Contain?

This substance is a mixture of flavouring, water, nicotine, propylene glycol (PG) or vegetable glycerin (VG). E-juice uses the same type of flavouring that food manufacturers use, so it's safe to consume and can be delicious. Meanwhile, PG and VG are liquids that help distribute the taste of the flavouring throughout the vape juice.

Is it Better to Use PG or VG?

In the vaping community, there is some debate about whether propylene glycol or vegetable glycerin provides a better mouthfeel. Here's a run-down of the benefits of using either type as a base for vape juice.

The Features of Propylene Glycol

PG liquid is usually thinner than VG, which means the cotton or the wax on the atomiser absorbs it quickly. It also produces less residue and is typically thinner than VG. As a result, it produces a cleaner overall vaping experience. Propylene glycol is also flavourless, so it does not affect the e-liquid's overall taste. It also produces a throat hit similar to cigarettes, which is why many former smokers choose this liquid. 

The Features of Vegetable Glycerin

If PG is thin, VG e-juice is more viscous. It tends to produce a considerable amount of residue on vapouriser parts, which could reduce an atomiser's lifespan. When using VG e-liquid, you need to clean your vape constantly.

Vegetable glycerin e-juice is also sweet—this substance is also used as a sweetener in sugar substitutes. Because of the liquid's thickness, VG creates thicker vapour clouds. If you're the type of vape enthusiast who likes dense clouds of smoke, you'd likely prefer VG over PG liquid.

Finally, VG liquids tend to produce smoother hits—most users report that vegetable glycerin-based e-juice has a gentler throat hit than the propylene glycol-based variety. However, some people dislike using VG because it can cause allergic reactions in a small part of the population. Some people report that they experience phlegm buildup because of regular VG e-liquid use. 


Choosing either VG or PG liquid comes down to preference. If you want a more substantial throat hit, choose PG. If you prefer thick clouds of vapour, go for VG. Before committing to a type of e-liquid, though, it's best to try both and see which one is the best fit.
