What Is Vape Juice, Exactly, and What Do I Need to Know About It?

Hello! It looks like you might be thinking about vaping. Well, you’ve stumbled across the right page. 

Are you looking into vape pens? Or, are you thinking about electronic cigarettes (eCigs)? No matter which style you want or need, you’ll need to know the break down of both.

Vape juice is present in both. But they are not the same. And neither are the types of vape juice used.

So, what is vape juice? How is it used? And what does it do for you? We’re about to tell you. Keep reading to get all the details!

The Break Down

Vape juice is the liquid that is put into electronic cigarettes. The electronic cigarette vaporizes the liquid. You then inhale the vapor.

The juice is stored in a cartridge. And when it’s heated up, you inhale the sweet flavors! But what is e-juice or e-liquid?

Vape juice is also referred to as e-juice or e-liquid. But the terms all refer to the same liquid. However, there are different types of vape juice.

And depending on what kind you buy, the ingredients and flavor differ. 

The Ingredients 

How is vape juice made? Let’s talk ingredients! 

There are very few ingredients placed into vape juice. Unlike cigarettes, vape juice consists of only water, propylene glycol or vegetable glycerin, artificial flavoring, and possible nicotine. Nicotine is not present in all vape juices.

About 90% of the juice is either propylene glycol or vegetable glycerin. And the remaining 10% is the flavoring and nicotine (if present). However, some juices contain propylene glycol and some contain vegetable glycerin while others contain both.

Let’s read more now to look at the differences. And we’ll find out exactly what is in vape juice!

Propylene Glycol

Vape juice that is made with propylene glycol is thinner. Because it has a thinner consistency than vegetable glycerin, it vaporizes completely. And it doesn’t leave a film in the back of your throat.

Not only does it not leave a thick film in your throat, but it doesn’t leave build up in the pen either. And because it turns to vapor so quickly, it hits more like a cigarette. So those who are wanting more of a cigarette feel, this is the better choice. 

Another great quality of propylene glycol is that it is tasteless and odorless. Both awesome traits to have in a vape juice if looking to taste the flavoring as is.

But, there are downfalls. Vape juices made with propylene are said to dry out the mouth and throat. So you can’t use it too consistently if this is a problem for you.  

There’ve also been reports of users experiencing side effects. Propylene glycol can cause irritation or allergic reactions. And users shouldn’t continue if side effects occur. 

Vegetable Glycerin

Luckily, there is another option! There have been little complaints of vegetable glycerin side effects. So, if you have a bad reaction to the propylene glycol, then this is the juice for you!

Vegetable glycerin is thicker. It will leave a film-like texture on the back of your throat. It’ll also cause buildup in the pen as well.

It’s less potent. And it won’t hit as hard or compare to a cigarette.

It has a sweeter taste to it. But that just adds to the sweetness of the flavoring. And thanks to its thicker consistency, it won’t leave your mouth dry! 


Ah, yes! Hybrids are awesome! Some vape juices come as a mixture of both ingredients. 

Depending on how you prefer it, the mixture will contain certain amounts of each. The mixture vape juices give the user the thick cloud of vape that the vegetable glycerin gives and the strong hit that the propylene glycol offers. 

Nicotine Levels

How much nicotine that is in the vape juice depends on your preference. And it’s not a requirement. Those who rape for recreational purposes often don’t use vape juice containing any nicotine. 

Nicotine levels in vape juice range from none and low to high and extra high. No nicotine would be 0mg. And it ranges all the way to 24mg.

A normal cigarette has 18mg of nicotine in a hit. But as concentration rises, the levels rise. So for someone who is making the transition from cigarette to eCig, a higher level of nicotine might work better.


The flavoring in vape juice is food grade. And only takes up about 10% of the actual makeup.

And the amount of flavors is endless. You can find just about anything that you’re looking for and give it a try.

Pens Vs eCig

Something that is important to consider before making a purchase is why you’re making the purchase in the first place. There is a difference between the vape pen and the eCig. Let’s break it down.

Vape Pen

Vape pens are used for recreational purposes. They have a similar shape to a normal writing pen. They are thin, long, and tube-shaped. 

And they come in several different colors or styles. There’s a pen to fit anyone’s style!


eCigs are for users who are beginning to coax themselves off of habits of using regular cigarettes. They make for an easier transition. The eCigs resemble actual cigarettes in their looks.

The eCigs are more limited on the colors and styles that they come in. But they do sometimes come in what looks like a cigarette pack. This gives the user a feeling that they are used to with regular cigarettes.
