What Is Vape Juice?

E-liquid, also called by the names e-juice or vape juice, is a liquid used in electronic cigarettes and personal vaporizers. It usually comprises propylene glycol (PG), vegetable glycerin (VG), food-grade flavorings, and nicotine.

The ratio of PG to VG determines the throat hit and vapor production of the e-liquid. Higher PG levels will produce more of a harsh throat hit, while higher a higher VG ratio will produce more vapor. Most vape juice brands will offer the same flavors in various PG/VG ratios to attract as many customers as possible.

Ordinarily, this product contains nicotine, an addictive substance found in tobacco that vape juice users need to help quit smoking. However, nicotine-free options are also available for those who do not want to consume nicotine.

There are endless vape juice flavors when it comes to vape liquids. Some of the most popular flavors include tobacco, menthol, fruit, dessert, and candy. But more unique flavors, such as coffee, tea, and even savory options like bacon and cheese, are available.

E-juice is most often sold in bottles ranging in size from 10ml to 100ml. The nicotine strength of the vape liquid is usually measured in milligrams per milliliter (mg/ml).

The most common nic strengths are 3mg/ml, 6mg/ml, 12mg/ml, and 18mg/ml. However, higher and lower options are also available for those who want more or less nicotine in their vape juice.

E-Juice Ingredients Explained

Now that you have a better understanding of vape juice, let’s take a closer look at the ingredients used to make it. They help turn regular chemicals into your favorite flavor. You’re about to understand why it makes your taste buds happy.

Propylene Glycol (PG)

Propylene glycol is a clear, odorless liquid that is used in many food and cosmetic products. It is also used in vape juice to produce the “throat hit” that smokers are accustomed to.

While PG is considered safe by the FDA, some people may experience allergic reactions when they use products that contain it. These reactions can include itching, redness, and swelling of the skin.

If you experience these reactions, you should switch to an e-liquid with higher VG content.

Vegetable Glycerin (VG)

Vegetable glycerin is a clear, odorless product that is made from vegetable oil. It is used in many food and cosmetic products, as well as in vape juice.

VG is thicker than PG and produces more vapor when it is vaporized. It also has a sweeter taste, which can affect the flavor of the e-liquid.

VG is considered safe by the FDA, but some people may experience digestive issues when they use products that contain it.

If you experience these reactions, you should switch to an e-liquid that has a higher PG content.


Vape juice flavorings are often derived from food-grade chemicals. They are used to give the e-liquid its desired flavor profile.

Anyone who’s ever picked up a bottle of vape juice knows that there are seemingly endless flavor options available, from strawberry kiwi to blue raspberry and all the tasty flavors inbetween, with new flavors coming out all the time. But have you ever wondered how those flavorings are made? It turns out that there’s a science to it.

Manufacturers add artificial or natural flavorings to the VG/PG base. These can be anything from essential oils to synthetic chemicals, and the exact mix of ingredients will vary depending on the desired flavor.

For example, strawberry vape juice might contain acetaldehyde and ethyl methylphenylglycidate for the characteristic fruity taste, while a chocolate flavor might use cocoa extract and dimethylcyclohexenone.

Once the desired flavors, such as peach pear or cookie butter, have been added, the juice is then ready to be bottled and sold. So next time you take a puff of your favorite candy king vape juice, remember that there’s much more going on behind the scenes than meets the eye.


This is a psychoactive substance that is found in tobacco products. It is also used in some vape juices to give users a similar feeling.

Nicotine is an addictive chemical that can harm your health because it’s a stimulant. If you’re sensitive to products like tobacco or caffeine, you shouldn’t vape or only vape zero nic e-juices.

It is vital to know the nic level of your e-liquid if you are trying to quit smoking cigarettes. If you pick up a bottle and see “Warning this product contains nicotine”, ask an employee of the shop if they offer a version without it.

Some vape juices do not contain any, while others have high levels. It is essential to read the labels carefully to make sure you are getting the right amount for your needs.

Nicotine Salts VS. E-Liquid

Nicotine salt e-liquid is a type of vape juice that employs nicotine salts rather than regular tobacco leaves’ nicotine. Nic salt e-liquids are generally 50/50 PG/VG. The goal of nic salts is to give more nicotine without being harsh. These types of e-liquids are often used in pod mods because they contain a lot of nicotine but very little vapor.

PG VS. VG Based Juice

PG Based

PG vape juice is preferred for people looking to get off a traditional tobacco product. You’ll get a more intense throat hit with this type of juice, but what you won’t get is a big thick cloud. This type of e-juice starts around 70% PG and is designed to simulate the feeling of smoking a cigarette.

VG Based

VG e-liquids are known for producing massive clouds. This higher VG e-juice begins at around 60% VG and is vaped at a higher temperature. Only lower nicotine concentrations are accessible because of this, so you’ll be hard-pressed to find anything above 6mg.

Is There a Best Ratio for Vape Juices?

Simply put: no. It comes down to you as an individual, the flavors you enjoy, your delivery system, and what you’re trying to get out of the experience. But we can help you find a good starting point, and then you can walk your path.

Good Starting Point for Vape Pen/New-to-Vaping Users

We see these products often being purchased by people who are new to vaping and/or trying to get off of traditional tobacco. These devices tend to have smaller tank surface areas and heat the liquid at a lower temperature.

VG is thicker than PG, so too much VG in this kind of product can result in frequent trips to the vape shop for new coils. Try starting with a 50/50 blend and see where it goes.

Good Starting Point for Mods

The higher the VG, the better. These mods have big tanks and operate optimally at higher temps.

However, it’s important to note that your coil’s resistance and wattage will have an impact on your experience. The higher a coil’s resistance, the less power it requires, and vice versa.

How to Choose the Right Vape Juice Flavors for You

There are a lot of factors to consider when choosing the best vape juice for your needs. The first thing to think about is what kind of flavors you like.

There are countless different flavors of vape juice on the market, so you should be able to find something that suits your taste buds. If you’re unsure where to start, try looking for a flavor similar to cigarette tobacco or even menthol flavors.

Once you’ve decided on a flavor, nicotine strength is the next thing to consider. Vape juices have different strengths, so you’ll need to choose one that is right for you.

Adult smokers probably want to start with a higher nic strength and then gradually reduce it over time. On the other hand, if you’ve never smoked before, you may want to start with lower nicotine strengths and then increase it if you find that you enjoy vaping.

Remember that nicotine is an addictive chemical. So take special care if you’ve never smoked before and want to try vaping.

Finally, choose a vape juice that is compatible with your vaporizer. Not all vape juices are compatible with all vaporizers, so check before buying.
