Introduction
Choosing the right liquid is essential for both your device's performance and your overall experience. At Vapor Authority, we often receive questions about what exactly goes into e-liquid and, more importantly, what substances are safe to vaporize. Understanding these components helps you make informed choices that protect your hardware and ensure a consistent draw. This guide will detail the approved ingredients for vape juice, the different types of e-liquids available, and the dangerous household items you must always avoid.
Warning: This content is intended for adults of legal vaping age only. Vaping products contain nicotine, which is an addictive chemical. These products are not intended for use by minors, non-smokers, pregnant or breastfeeding women, people with heart conditions, high blood pressure, or asthma. Consult a physician if you have concerns about whether vaping products are appropriate for you.
Understanding the Components of E-Liquid
To understand what you can use for vape juice, you must first understand the four primary ingredients found in professional e-liquids. These ingredients are specifically chosen because they can be aerosolized at specific temperatures without damaging the heating element or creating immediate mechanical failure.
Vegetable Glycerin (VG)
Vegetable Glycerin is a thick, odorless liquid typically derived from plant oils like palm, soy, or coconut. In the context of e-liquid, VG is responsible for the density of the vapor produced. Because it is a viscous substance, liquids with high VG content are thicker. VG has a slightly sweet natural taste, which can influence the final flavor profile of the liquid.
Propylene Glycol (PG)
Propylene Glycol is a much thinner, odorless liquid than VG. While it does not produce large clouds, it is an excellent carrier for flavorings and nicotine. PG provides the "throat hit" that many adult vapers look for. Because of its low viscosity, it is absorbed into atomizer wicks much faster than VG.
Nicotine
Most e-liquids contain nicotine, though nicotine-free (0mg) options are common. The nicotine used in e-liquid is purified from tobacco plants. It is available in two primary forms: freebase nicotine and nicotine salts. Each serves a different purpose and requires different hardware configurations.
Flavorings
The flavorings used in e-liquids are concentrated, food-grade additives. However, it is important to note that these are not the same as the extracts you find in a grocery store baking aisle. E-liquid flavorings are specifically formulated to be stable when heated and inhaled as an aerosol.
Why You Should Never Use Household Liquids
A common question among beginners is whether household liquids like water, juice, or oils can be used as a substitute for e-liquid. The short answer is no. Using anything other than specifically formulated e-liquid can result in severe damage to your lungs and your device.
The Danger of Oils and Essential Oils
You must never put any form of oil into a vape device. This includes vegetable oil, olive oil, or essential oils used for aromatherapy. When oils are vaporized and inhaled, they can settle in the lungs and lead to a serious condition known as lipid pneumonia. Vaping hardware is designed to atomize water-soluble liquids, not lipids.
Why Water is Not a Substitute
While it might seem harmless, putting water into a vape tank is highly problematic. Water has a much lower boiling point than VG or PG. When the coil heats up, the water can turn into steam instantly, potentially burning your mouth or throat. Furthermore, water does not provide the viscosity needed to keep the wick saturated, which will lead to the heating element burning out almost immediately.
Alcohol and Sugary Liquids
Alcohol should never be vaped. Inhaling alcohol vapor can be toxic and highly irritating to the respiratory system. Similarly, liquids with high sugar content, such as soda, fruit juice, or syrup, will cause immediate hardware failure. The heat from the coil will caramelize the sugar, turning it into a thick, black gunk that destroys the coil and tastes like burnt carbon.
Matching E-Liquid to Your Hardware
Not all e-liquids are compatible with every device. Using the wrong "thickness" of juice can lead to leaking or "dry hits," where the cotton wick burns because the liquid is too thick to flow into it.
Sub-Ohm Vaping and High VG Liquids
Sub-ohm vaping involves using a coil with a resistance below 1.0 ohms. These devices typically operate at higher wattages and require thicker e-liquids.
- Best Ratio: 70% VG / 30% PG or higher.
- Nicotine Strength: Low (typically 3mg or 6mg).
- Experience: Large vapor production and a smoother throat hit.
Sub-ohm tanks have large wicking ports to accommodate thick VG. If you use a high-PG liquid in these tanks, the liquid will be too thin and will likely leak out of the airflow vents. For a closer look at the category, browse sub-ohm tanks and related tank options.
Pod Systems and High PG Liquids
Pod systems are compact devices that usually use coils with a resistance above 1.0 ohms. These are designed for a more restricted draw.
- Best Ratio: 50% VG / 50% PG.
- Nicotine Strength: Higher (nicotine salts ranging from 25mg to 50mg).
- Experience: Stronger throat hit and more discrete vapor production.
The small wicking holes in pod systems cannot absorb thick VG quickly enough. If you use high-VG juice in a small pod, you will likely experience a burnt taste after just a few puffs. If you want to compare device styles, take a look at pod systems.
Nicotine Types: Freebase vs. Nicotine Salts
Understanding what you can use also depends on the type of nicotine your body and device prefer.
Freebase Nicotine
This is the traditional form of nicotine used since the early days of vaping. It has a higher pH level, which makes it feel "harsher" on the throat at higher concentrations. This is why freebase nicotine is usually sold in lower strengths like 3mg, 6mg, or 12mg. It is the standard choice for those using box mods and sub-ohm tanks.
Nicotine Salts
Nicotine salts are created by adding benzoic acid to freebase nicotine. This lowers the pH level, resulting in a much smoother throat hit even at very high concentrations. This allows users to use 30mg or 50mg nicotine without the intense throat irritation. Nicotine salts are specifically intended for use in low-power pod systems and should never be used in high-wattage sub-ohm devices. You can browse our nicotine salt e-liquids to see the category in more detail.
The Importance of Professional Manufacturing
At Vapor Authority, we only carry e-liquids manufactured in the United States using food-grade and pharmaceutical-grade ingredients. This is a critical distinction when considering what you can use for vape juice. Professionally made liquids undergo rigorous testing to ensure consistency and purity. If you want to explore what we currently feature most prominently, visit our best sellers.
Homemade "DIY" liquids are an option for some enthusiasts, but they require a deep understanding of chemistry and safety. If you choose to explore DIY, you must use USP-certified (United States Pharmacopeia) Vegetable Glycerin and Propylene Glycol. Never experiment with random ingredients from your kitchen or medicine cabinet.
Storage and Handling of E-Liquids
Once you have the correct liquid, how you store it affects its quality. E-liquid is sensitive to light, heat, and oxygen.
- Avoid Sunlight: UV rays can break down nicotine and cause flavorings to oxidize, leading to a peppery taste or a change in color.
- Keep it Cool: Excessive heat thins the liquid, which can lead to leaking. Store your bottles in a drawer or cupboard.
- Seal Tight: Always keep the cap tightly closed to prevent oxygen from degrading the ingredients.
- Safety First: E-liquids should always be stored in a secure location out of reach of children and pets.
Hardware and Power Management
When discussing what can be used in a device, we must also address the power source. Many advanced devices use external batteries, such as 18650 or 21700 lithium-ion cells. These require specific care to ensure the device operates safely with your chosen e-liquid.
Battery Safety
If you are using a box mod or any device with removable batteries, follow these essential safety steps:
- Inspect Wraps: Never use a battery with a torn or peeling plastic wrap. The metal underneath is the negative terminal, and if it touches the mod's body or another metal object, it can short-circuit.
- Use a Dedicated Charger: While many mods allow for USB charging, using an external high-quality charger is safer and extends the life of your batteries.
- Avoid Loose Batteries: Never carry loose batteries in your pocket or bag. If they touch keys or coins, they can vent. Always use a plastic battery case.
- Married Batteries: In devices that use two or more batteries, always use a "married" pair. This means the batteries are the same brand, model, and age, and they are always charged and discharged together to ensure they share the load equally.
Choosing the Right Flavor Profile
Once you understand the technical requirements, the choice comes down to personal preference. The market is divided into several main flavor categories:
- Tobacco: Aimed at those who prefer earthy, smoky, or woodsy notes.
- Menthol and Ice: Provides a cooling sensation on the throat, often paired with fruit or mint.
- Fruit: Includes everything from single-note flavors like apple or strawberry to complex tropical blends.
- Dessert and Pastry: Rich flavors like custard, cheesecake, or glazed donuts.
- Beverage: Flavors mimicking coffee, soda, or lemonade.
We test every e-liquid line before it is added to our inventory to ensure that the flavor profiles are accurate and that the liquids do not contain unnecessary additives that could prematurely degrade your coils. For a preview of what’s arriving next, check out our new arrivals.

FAQ
Can I use regular food extracts as vape juice?
No, you should never use grocery store food extracts. These often contain alcohol, oils, or sugars that are dangerous to inhale and will ruin your vaping hardware. Professional e-liquid flavorings are specifically formulated for inhalation and are suspended in PG or VG.
Is it safe to put a few drops of water in my tank to thin the juice?
You should avoid putting water in your vape tank. Water boils at a lower temperature than e-liquid components, which can cause "spit-back" or steam burns. If your juice is too thick, it is better to switch to a liquid with a higher Propylene Glycol (PG) content.
What happens if I put essential oils in my vape?
Putting essential oils in a vape is extremely dangerous. Inhaling vaporized oils can lead to lipid pneumonia, a serious lung condition where oil droplets become trapped in the lungs. Vaping devices are designed only for water-soluble ingredients like PG and VG.
Can I mix two different types of e-liquid together?
Yes, you can mix different e-liquids as long as they are both legitimate vaping products. Many vapers mix flavors or combine different nicotine strengths to reach a specific level. However, ensure the resulting VG/PG ratio is still compatible with the coil you are using.
