Vape Juice: What Is It and How Is It Made?

Vape juice, e-juice, vaping liquid, e-liquid. If you've spent any time browsing around a vape shop, you've run into at least one of these names.

If you're a beginner buying their first starter kit, it's possible you have questions. Questions such as: What is e juice? Why is it used? What ingredients are in it?

Even experienced vapers might have questions about e-juice. We should know everything about what we're putting into our devices.

We've put together a guide with all the information you'll need. With this, you'll know everything about what you're putting into your vaping devices.

What is Vape Juice?

You can't vape without vape juice. It's the blood of your device, the fuel that creates that delicious vapor.

To start, you pour e-juice into your vaping device's tank. From there, it gets heated up until it forms a thick vapor, which you then inhale. A vaping device without e-juice burns the inner workings of the device.

E-juice comes in bottles of all shapes and sizes. Most common are glass bottles, often with droppers included in the cap to make dripping easy. Some come in squeeze bottles.

E-juice comprises of a small set of ingredients that create a huge variety of different flavors and consistencies. When you ask yourself "what is in vape juice", a large percentage of it is either a VG or PG base. Food-grade flavorings, water, and nicotine are then added to those bases to create a tasty e-juice.

How Does it Differ From Tobacco?

The biggest difference between the two is that vape juice is a liquid that gets heated up to make vapor. Tobacco, on the other hand, is an organic material that burns to create smoke.

Inhaling vapor is a much safer alternative to inhaling smoke. It's kinder to your lungs and your overall health.

And, for those of us who have kids or other family members around, there is no harm at all from second-hand vaping.

Another difference is that e-juice is a mix of only a handful of ingredients, whereas tobacco is a combination of almost 600 ingredients. A large portion of those ingredients is carcinogenic.


VG (otherwise known as vegetable glycerin) is a liquid made from coconut oil, palm oil, or soy oil. It's colorless and odorless and used for different food products. It's also sometimes used in lotions and other medical items, as glycerin is great at hydrating skin.

When ingested, VG has natural sugary sweet flavor. E-juice uses this property to their advantage to give a sweetened effect to their flavors without having to add sugar. Because of this, VG is most often used as the base for the dessert and fruit flavors of e-juice.

How VG Affects Your Vape

If you've ever gone to a vaping competition, you've seen the massive and thick clouds. You've seen cool vape tricks done with nothing but the delicious vapor the competitor exhales.

Those kinds of clouds are only achievable with VG liquids. PG can give you nice clouds as well, but VG is the true star when it comes to making a spectacular display.

This is because VG is a lot thicker of a liquid when compared to PG. With this in mind, if you vape a lot of VG, you'll want to keep a closer eye on your device. The thickness of the liquid can cause residue to build faster.

VG also means that whatever you're vaping, it will have a sweet tang that is inherent to the base itself.


PG (also known as propylene glycol) is a synthetic liquid that is from the same chemical family as alcohol. Like VG, it is colorless and odorless and used for a lot of different processed drinks and foods.

It has no flavor on its own, presenting itself as a blank slate for e-juice makers to do whatever they want to it. Because of this, a whole variety of different e-juices use PG as a base. As it has a stronger feeling when inhaled, a lot of makers like to use it for tobacco-inspired flavors.

How PG Affects Your Vape

If you're making the switch from smoking cigarettes, PG could be a great way to start. It has a much stronger throat hit than VG, making you feel the vapor as you inhale. This doesn't replicate the feeling of smoking cigarettes, but it does make for a decent substitute.

Some people find that this stronger throat hit leaves their throat feeling irritated or scratchy. This feeling will go away a few days after you've stopped using the PG liquid. If this occurs, you should switch to VG instead.

PG is not as thick as VG, having more of a syrup-like consistency. Due to this thinness, PG isn't known to create as large of clouds as VG liquids. Regardless, cloud chasers can still be happy with PG vapor production.

PG and VG Mixed

One of the best things about the vaping experience is the fact that we get to customize it to our own personal preference. In the vaping world, you can have the best of both worlds.

Getting a mixed liquid of PG and VG can get you the kind of vape you want. If you want that strong throat hit but still want to create huge vapor clouds, the go for a 50Pg/50VG liquid. If you'd like a small throat hit but want even larger clouds, 30PG/70VG would be your perfect match.


These food-grade additives are what make your e-juice shine with a life of its own. It's that burst of citrus, the tangy sweetness.

When it comes to e-juice flavors, the sky is the limit. You can find flavors ranging from cherry soda to creamy custard. You can also find menthol flavors and flavors that remind you of the tobacco you used to love.

Only the highest quality of food-grade flavorings make their way to e-juice liquids.

Flavorings to Avoid

Although all flavors used in e-juice are food grade, which makes them fine to eat, some of them create problems when inhaled.

The most dangerous ingredient is diacetyl. When inhaled in large amounts, this chemical causes bronchiolitis. Diacetyl is most often used as an additive to popcorn to give it that delicious buttery flavor.

Scientists have tested diacetyl many times for its use in food, but now its use as an inhalant is under close study. Avoidance with this ingredient is the best course of action.

Acetyl propionyl and acetoin are being used as alternatives to diacetyl but are still proving to be a problem. These two chemicals react with and strengthen even the smallest traces of diacetyl.

There isn't concrete evidence if they are harmful on their own, but their reaction with diacetyl make it best to avoid them altogether.


Nicotine is the addictive substance found in all cigarettes. There is a certain amount of nicotine found in a lot of different e-juices as well. But the great thing is that you can find e-juices without nicotine, letting you enjoy vaping without the fear of addiction.

As vaping is an alternative to smoking, some people find that the addition of nicotine is what they need to lay off the cigarettes. Over time, a vaper can lower the amount of nicotine they use until they are vaping nicotine-free.

The range of nicotine found in e-juice can range from 0mg all the way to 24mg. Some can go even higher, though such high quantities aren't meant for beginners.

The best way to know what amount works for you is to start off small and then increase the nicotine level in increments. Even if you were once a smoker, it's better to start small until you know what your tolerance is.

The Process

Putting these different ingredients together isn't a difficult process, but it does take an experienced hand. Getting the measurements correct takes a lot of practice and know-how.

First, the selected flavorings get added to the VG/PG base, mixing until the flavors incorporate. A little flavoring can go a long way when added to VG or PG, so a small amount is all you need.

Next is the nicotine, adding the desired amount and then mixing the liquid together once more.

The last step is to let the e-juice steep for however long the maker decides. This allows the flavors to sink into the base in a stronger way, making the e-juice more flavorful and tasty.
