What Is Vape Juice?

Vape juice, e-liquid or e-juice, is a liquid in electronic cigarettes and personal vaporizers.

Vape juice typically consists of propylene glycol (PG), vegetable glycerin (VG), nicotine, and added flavorings. The juice in a vape pen creates vapor clouds. This is not the same as the smoke you find with traditional cigarette smoking.

Even though these vapor clouds are not smoke, they do have in common the presence of nicotine. You will find different nicotine strengths depending on the vape juice you choose.

Some zero-nicotine vape juices are available for those who like the experience of vaping but want to enjoy it without the added nicotine buzz. Sometimes former cigarette smokers start with higher nicotine strengths and then taper down to vape juices with lower nicotine as they get used to vaping.

Vape juice also comes in different bottle sizes and a wide variety of flavors, with something to suit every taste.

Vape Juice Ingredients

Vape Shack offers vape juices and e-liquids containing several ingredients that form the ideal base for quality vaping. Each of our options is loaded with flavor for the ultimate vaping experience!

You will typically find propylene glycol (PG), vegetable glycerin (VG), and nicotine in a vapor base. The combination of these ingredients yields a satisfying puff each time you vape, whether using a rechargeable pen or a disposable one.

Propylene glycol is an organic compound that carries the flavor of the vape liquid and also works to produce a consistent vapor. It’s typically used to retain and distribute flavor. PG is a common food additive, so it’s a non-toxic ingredient and totally safe for human consumption. You may often find it in medicines, cosmetics, and food products. 

Vegetable glycerin is a bit thicker than Propylene glycol, and this is the ingredient responsible for creating the larger vapor clouds. Found in a number of products, it’s a colorless and odorless ingredient that is produced from plant oils. Just like PG, VG is non-toxic and safe for consumption. 

Nicotine, an alkaloid, is found in the nightshade family of plants. It acts as a stimulant in small amounts and has been used medicinally for centuries. Nicotine is an optional ingredient, and you will find many e-juices that are produced with no nicotine at all. If you wish, you can purchase it separately and add it to your e-liquid. 

Different Types of E-Liquids  

VapeShack provides you with an unlimited variety of flavors and blends to match your taste. You can find e-juices with different nicotine strengths and ratios. Knowing which e-liquid suits your vape is important so that you don’t end up wasting money on juice you can’t enjoy.

Here’s a short breakdown of liquid types and vapes they are used with. 

70/30 Vape Juice 

70/30 vape juice is a high VG liquid, meaning it contains 70% vegetable glycerin and 30% propylene glycol. These vape juices are meant to be used with Sub-Ohm devices. The high concentration of VG results in a sweeter and richer flavor profile of an e-liquid and produces considerably thicker vapor clouds.

Using 70/30 vape juice on a vaporizer will not give it the same taste since the coil will have difficulties absorbing the thick VG liquid. 

50/50 E-Juice

The concentration of 50% VG and 50% PG is the most picked one among former smokers. This e-liquid is suitable for starter kits and can contain even 20mg of nicotine, the ideal strength for those just switching to vape. 

Nicotine Salts

If 20mg of nicotine doesn’t really give a strong punch, nic salts are the way to go. Unlike other vape juices, these ones are high in nicotine and won’t be harsh on your throat. Current smokers will find nicotine salts enjoyable because they absorb faster and give the desired nicotine punch. You won’t be craving a regular cigarette anymore. 

Nicotine salts are suitable for less-powerful kits.

Bar Juices

Bar juices are those liquids that replicate the flavor of disposable vapes. You can usually find them in 10ml bottles filled with nic salts, hence, they are best for Sub-Ohm devices. Disposable vapes have an extra sweet and strong flavor profile, hence, they’ve been quite popular over the years. 

If you don’t want to own a vape for a couple thousand puffs like Elf Bar or Flum, you can now purchase bar juices instead.

Nicotine Salts vs Sub-Ohm (Freebase)

Nicotine salts and freebase nicotine are two different forms of nicotine that are commonly used in e-liquids and vaping products. Here's a brief overview of the main differences between the two:

Chemical structure: Freebase nicotine is a form of nicotine that has been extracted from tobacco leaves and is in its purest form. Nicotine salts, on the other hand, are created by adding an acid to freebase nicotine, which creates a salt. This chemical alteration affects how the nicotine is absorbed by the body.

Nicotine delivery: Because of the chemical structure of nicotine salts, they are generally absorbed more quickly and efficiently by the body than freebase nicotine. This means that users may experience a stronger and more immediate nicotine hit when using nicotine salt e-liquids, compared to freebase nicotine e-liquids.

Smoothness: One of the main advantages of nicotine salt e-liquids is that they tend to be smoother and less harsh on the throat than freebase nicotine e-liquids. This is because the addition of an acid to the nicotine lowers the pH level of the e-liquid, which makes it less alkaline and therefore less irritating to the throat.

Flavor: Nicotine salts also tend to enhance the flavor of e-liquids, particularly at higher nicotine concentrations. This is because the lower pH level of the e-liquid allows for more of the flavor compounds to be released.

Overall, the choice between nicotine salts and freebase nicotine will depend on individual preferences and vaping habits. Some vapers prefer the strong and immediate nicotine hit of nicotine salts, while others prefer the smoother and more gradual nicotine delivery of freebase nicotine. It's important to choose the right nicotine strength and e-liquid formulation based on your individual needs and preferences, and to consult with a healthcare professional if you have any concerns about nicotine use.

Which Type of E-Liquid Should I Choose?

The type of e-juice you need depends on the vape device you’re using. The flavor and vaping experience highly depends on the ratio of VG:PG, so using the wrong ratio may hurt your throat or make a liquid taste blend. 

Pod Users

Pod users like Smok Novo and Voopoo Drag Nano should opt for nic salts and freebase e-liquids with or without nicotine. These are low-powered devices and are very compatible with thinner liquids. They work great with liquids containing up to 20mg of nicotine. 

Pods are great starter vapes as they resemble the smoking experience. You inhale the vapor that goes to your lungs before letting the vapor out.  

Balanced 50% VG and 50% PG liquids are ideal for pods. You will have a richer flavor, but less thicker clouds than with more powerful devices. Balanced liquids aren’t usually harsh on the throat, so you will have a smooth vaping experience. 

Sub-Ohm Users

Sub-Ohm users like Voopoo Drag and Smok Prince Stick are famous for their thick clouds of vapor. These devices have coils with thick holes, allowing better liquid absorption. You can opt for thicker juices like nic salts and Sub-Ohm vape juices. 

Unlike pods, when you inhale the vapor from Sub-Ohm vape kits, the vapor goes straight to your lungs, and you don’t hold it in your mouth first. 

You can use high VG liquid containing 80% VG and 20% PG or 70% VG and 30% PG. You will enjoy the rich flavor and thick clouds. Note that these liquids are usually sweeter because vegetable glycerin naturally adds sweetness to e-juices. 

What Nicotine Strength Should I Choose?

Most e-liquids come with added nicotine in various strengths. The strength you go for will solely depend on your unique preference and nicotine cravings. 

Using high-powered vape kits means you will likely prefer to keep the nicotine content as low as possible since higher amounts may be harsh for the throat. The ideal level is somewhere between 3mg to 6mg.  

Low-powered pod users can increase the nicotine strength to 20mg in nicotine salts and freebase liquids. The nicotine content may also depend on how many cigarettes you used to smoke:

  • 1-5 cigarettes per day equals about 5mg of nicotine in nic salts and 3mg in 50/50 freebase;
  • 6-15 cigarettes per day equals about 10mg in nic salts and 6mg in 50/50 freebase;
  • 15 or more cigarettes per day equals about 20mg in nic salts and 12mg in 50/50 freebase liquids

How Do E-Cigarettes Work?

Most vapes are powered by rechargeable batteries, except for disposable vapes that you throw away once the battery is depleted. Each of them, however, uses e-liquid that you inhale. Inside a vape, there is a coil that heats up the liquid inside as you inhale and transforms it into clouds of vapor. 

Basically, it mimics the smoking experience but without harmful chemicals present. Some vapes come with a coil or pod that has a limited lifespan. You can purchase pods or coils to replace the old ones and continue to enjoy your vape. Worth noting that there are also pre-filled cartridges so that you don’t deal with filling the liquid up but simply exchanging the cartridge.

Refilling an Electronic Cigarette: What You Should Know

Some people are hesitant to switch to an electronic cigarette if they are concerned about refilling it with e-juice and making a mess or a mistake that causes the electronic cigarette to malfunction.

Fortunately, refilling electronic cigarettes is an incredibly easy process. Users take the cartridge out of the e-cigarette and carefully drip the vape juice into the empty cartridge until it is completely refilled.

When you switch to an electronic cigarette, you can save money by purchasing the e-juice in bulk and refilling your device as needed. We suggest that before you purchase any vape juice in bulk, you try a small quantity to be sure you like the flavor. Once you know what flavors suit you best, you will know exactly what to stock up on for the best and most satisfying vape experience.

If you still think refilling a cartridge is a hassle and do not want to try it, another great option is available. Prefilled cartridges make it easy to pull out the empty cartridge and snap a new one into your device.

The main ingredients in vape juice are propylene glycol (PG), vegetable glycerin (VG), flavorings, and nicotine (optional). Some vape juices may also contain distilled water, alcohol, or other additives.

How is vape juice made?

Vape juice is made by mixing the main ingredients (PG, VG, flavorings, and nicotine) in specific proportions and then allowing them to steep to enhance the flavor. The ingredients are typically mixed in a sterile environment to ensure quality and safety.

What is the difference between VG and PG in vape juice?

VG (vegetable glycerin) is a thicker and sweeter ingredient that produces thicker vapor clouds, while PG (propylene glycol) is a thinner ingredient that provides a stronger throat hit and carries flavors better. Vape juices may contain a combination of both VG and PG to balance the vapor production, throat hit, and flavor.

What is the role of nicotine in vape juice?

Nicotine is an optional ingredient in vape juice that provides the "buzz" or "kick" that many users seek. It is a highly addictive substance that is derived from tobacco leaves and is typically available in a range of nicotine strengths to suit different users.

What are the different nicotine strengths available for vape juice?

Nicotine strengths for vape juice typically range from 0mg (nicotine-free) to 60mg or higher (for strong or heavy smokers). Some common nicotine strengths include 3mg, 6mg, 12mg, and 18mg.

What is the shelf life of vape juice?

The shelf life of vape juice can vary depending on factors such as the quality of ingredients, the storage conditions, and the nicotine content. Generally, most vape juices have a shelf life of around 1-2 years if stored properly.

How do I store vape juice to ensure it lasts longer?

To ensure that vape juice lasts longer, it should be stored in a cool, dry, and dark place away from direct sunlight and heat sources. It should also be kept in a tightly sealed container to prevent air exposure, which can cause the flavor and nicotine to degrade over time.

What are some common flavor profiles for vape juice?

Common flavor profiles for vape juice include fruity, dessert, menthol, tobacco, and candy flavors. Some popular flavors include strawberry, grape, watermelon, and mint.

Can I mix different flavors of vape juice together?

Yes, many vapers enjoy mixing different flavors of vape juice together to create their own unique blends. However, it is important to ensure that the flavors are compatible and that the nicotine strengths are balanced to avoid any negative effects.

How do I know which nicotine strength and flavor profile to choose?

The best nicotine strength and flavor profile for you will depend on factors such as your personal preference, smoking history, and vaping habits. It may be helpful to start with a lower nicotine strength and experiment with different flavors until you find one that you enjoy.

What are the potential health risks of using vape juice?

While vaping is generally considered to be less harmful than smoking, there are still potential health risks associated with using vape juice. Some of these risks include lung irritation, allergic reactions, and exposure to harmful chemicals. It is important to use vape juice responsibly and to consult with a healthcare professional if you have any concerns.

Is it safe to vape without nicotine?

You can find many liquids that are sold without added nicotine. Due to the lack of in-depth research, there is no clear evidence of whether vaping is totally safe and whether it leads to any consequences. As for people looking for alternatives to quit smoking, vaping may be more effective with nicotine. Otherwise, there is a risk of former smokers returning to their old habit of smoking cigarettes. What many smokers prefer to do is to vape liquids with high concentrations of nicotine and gradually decrease the nicotine strength.

What are the types of nicotine?

There are three types of nicotine in e-liquids:

  • Freebase nicotine
  • Nicotine salts
  • Hydrid nicotine

Freebase nicotine is a common ingredient in many e-juices. It’s the pure form of nicotine and it gives a strong punch when the liquid is heated. Vapers who take a few puffs throughout the day usually go for liquids with freebase nicotine.

Nicotine salts are gentler than freebase nicotine; they are smoother and less harsh on the throat. Nicotine salts are regular nicotine, just like freebase, but with a balanced level of pH. 

Finally, hybrid nicotine is a blend of freebase and nic slats. With hybrid nicotine liquids, you get a smoother experience and a powerful kick of nicotine.

Can I refill disposable vape kits with e-juice?

No, disposable vapes cannot be re-filled with e-liquid. They come pre-filled and have a closed tank. The same goes for pre-filled pods. When a disposable vape is depleted, you throw it away and replace it with a new one. When the liquid in the pre-filled pod is finished, you simply need to exchange it with a new one.
