We don’t need to know why you chose to start vaping. There are many reasons why you might choose to vape. Some people start vaping to get rid of smoking. Perhaps you learned that vape juice comes in different flavors. Therefore, it is a whole experience to try them. Regardless of the reason, you need to know which vape juice ingredients are because you must be aware of what you are putting into your body.

Vape Juice Ingredients

People put in their vape or electronic cigarette a liquid called vape juice. It may or may not contain nicotine because it depends on the vape juice that you buy. By heating the e-liquid in your vape, you generate a cloud of vapor.

What you inhale when vaping is the e-liquid you have chosen. So, you need to know which the main vape juice ingredients are. Those main ingredients are four: vegetable glycerin, propylene glycol, flavoring, and nicotine.

“All of these chemicals are considered “Generally Recognized As Safe (GRAS)” by the FDA for human ingestion.”

Still, the effects of ingesting these chemicals through the vapor are not yet known. Only time and research will tell how these chemicals react in our bodies.

What’s in Vape Juice?

You need to take good care of what goes into your body. So let’s take a closer look at what is in vape juice. What are those ingredients used for, and how do they affect your vaping experience?

Vegetable Glycerin

Glycerol or vegetable glycerin is a thick and transparent liquid. It generally comes from palm trees and soybeans. Also, it can come from animal fat. However, that option is less common. The FDA approved vegetable glycerin as a generally recognized safe chemical for humans to ingest. Nevertheless, we still don’t know the health effects that can come from inhaling vegetable glycerin.

What is VG Used For?

The food industry uses vegetable glycerin as a sweetener. It also retains moisture. Therefore, it helps foods to homogenize and thicken certain ingredients. Food products like gel capsule pills, yogurt, cheese, baked goods, and other processed foods may also have vegetable glycerin.

You can also find vegetable glycerin in your skin cream because it preserves moisture and increases the other ingredients’ solubility. Therefore, it makes the cream more absorbable through the skin. Other household products containing vegetable glycerin are deodorant, shampoo, toothpaste, makeup, and eye drops.

How Does VG Affect Your Vaping Experience?

Vegetable glycerin can affect the quantity of vapor produced. The vapor produced increases because of the liquid’s viscosity. As a result, the clouds will get thicker with the ratios of vegetable glycerin in the e-liquid. However, it has a relatively smooth and soft throat hit.

Dry heats may occur because of the thickness of vegetable glycerin because it makes it harder to wick for your vape coil. Also, it will take a longer time for a high ratio of vegetable glycerin to saturate your vape coil’s cotton.

Since it has a goopy consistency, it will be harder to clean vegetable oil from your tank. That is in comparison to propylene glycol.

Propylene Glycol

“Propylene Glycol is a chemical compound having the formula CH3CHCH2OH.” It comes from petroleum, and it is an odorless and colorless liquid. Companies utilize propylene glycol in products for pets and people. The FDA approved propylene glycol for human ingestion. However, we still don’t know the long-term effects on health that inhaling propylene glycol can cause. Also, it isn’t considered as cancerous.

What is PG Used For?

Since propylene glycol can retain moisture, people commonly use it as a food additive. Because it makes the ingredients thicker, it also helps to bind together the different ingredients.

The most common foods that utilize propylene glycol as an additive are: commercial food coloring, boxed cake mix, packaged roasting, soft drinks, ice cream, and salad dressings.

Also, you can find propylene glycol in several cosmetic products: deodorant, toothpaste, ointments, mouthwash, lotion, and shampoo.

How Does PG Affect Your Vaping Experience?

E-juices utilize propylene glycol to transport the flavoring. As a result, the higher the propylene glycol ratio, the sharper the flavor. Also, if you increase your propylene glycol, you will get a stronger throat hit.

In comparison to vegetable glycerin, propylene glycol has a thinner consistency. Therefore, it will be easier to clean it off your vape depending on the vaping device that you use. However, you could have some leaking issues if you use a high ratio of propylene glycol.

You need to consider that if you’re sensitive to propylene glycol, this will give you an allergic reaction. You may feel skin irritation or a sore throat. So, in that case, you would need to look for juice with a higher ratio of vegetable glycerin instead.


E-juices utilize a flavor concentrate that is a combination of artificial and natural flavoring. That is to replicate a drink or food’s taste. The Flavor Extracts Manufacturers Association approved certain flavoring concentrates as food grade. Therefore, those are the ones that e-juice manufacturers utilize. Nevertheless, we still don’t fully understand as of yet the inhalation effects of those concentrates.

What Are Flavoring Concentrates Used For?

You can find flavoring concentrates in candy, soda, and baked goods. You can also find flavoring concentrates in other processed foods which contain any kind of artificial flavoring. The flavoring concentrates allow the vape juice to have a replica of a specific taste. So, you get the feeling of eating a certain specific food or ingredient.

How Does Flavoring Concentrates Affect Your Vaping Experience?

You will not find more than 10% of flavoring concentrates in your e-juice. You will not find any oil-based flavorings in your e-juice.

Certain specific ingredients can be hazardous if you inhale them. As an example, flavorings like acetyl propionyl, acetoin, and diacetyl can be hazardous to your health. However, cigarettes have between 10 and 100 times more diacetyl than any e-juice. So, you will need to consider that when you check your e-juice contents.


You can find nicotine in certain specific plants like tobacco, potatoes, eggplants, and tomatoes. It is an alkaloid. Nicotine is considered a substance that is highly addictive. It is one of the main reasons people find it so difficult to quit smoking cigarettes.

Even though we consider nicotine as a stimulant, it can also help the person relax. Another misconception is that nicotine can cause cancer in cigarette smokers. But it is actually the tar and other additives that cigarettes cause cancer when you inhale them.

The quantity of nicotine in e-liquids is expressed as a percentage of the total volume. A 6 mg e-liquid is a mix with 6 milligrams of nicotine per 100 ml of e-liquid. Reflected in percentage, a 6 mg e-liquid is labeled as 0.6%.

What is Nicotine Used For?

Nicotine can be helpful to smokers who wish to quit smoking. That is why you may be able to find nicotine in e-liquid, nicotine patches, nicotine inhalers, and nicotine gum.

Since nicotine causes intense cravings, it is tough to quit cold turkey smoking cigarettes. So that is the reason why some nicotine replacement therapies use nicotine. Because it will help the person quit smoking cigarettes. Also, vaping provides a less harmful way to get a smoking sensation.

How Does Nicotine Affect Your Vaping Experience?

You can find vaping nicotine in different levels. You may find it in 12 mg, 6 mg, 3 mg, and 0 mg, known as freebase. So, as you can see, some vape juices don’t have nicotine.

The higher your nicotine level, the harsher your through hit will be. Also, it would be best if you remembered that it has a peppery taste. Therefore, that can cause the flavor to be harsher.

Two types of nicotine exist nicotine salts and freebase nicotine. Another common name for freebase nicotine is regular nicotine. On the other hand, nicotine salts are pretty new. You can find nicotine salts in strengths of 25 mg and 50 mg. It differs from freebase nicotine because you can vape with a higher nicotine strength without getting a harsh taste. Therefore, it’ll be a vaping experience that comes closest to getting the same amount of nicotine as a cigarette provides.

Companies that make bottles of e-juice must child-proof them because children could overdose on nicotine. If children overdose on nicotine, it would be fatal for them.

The Bottom Line

So, as you can see, you might be able to find some harmful ingredients in vape juice. However, there aren’t many. If you want to get the healthiest vape juice, you should find the safest vape juice brands. Also, make sure to read the labels on the products to ensure that you’re getting what you want.
