Whether you call it vape juice, e-liquid, vape juice, or ejuice: vape liquids are what vapes are built around. Today we will be looking at some of the most common questions about vape liquids and giving you the information you need to always get the most out of your juice.
What Is Vape Liquid?
Vape liquid, also known as e-liquid or vape juice, is the substance used in electronic cigarettes and vaporizers to create vapor. It typically consists of propylene glycol (PG), vegetable glycerin (VG), nicotine (optional), and flavoring agents.
What Are the Main Ingredients in Vape Liquid?
The primary ingredients in vape liquid include:
Propylene Glycol (PG): A thin, odorless liquid that provides a stronger throat hit and carries flavors well.
Vegetable Glycerin (VG): A thicker liquid that produces more vapor and has a slightly sweet taste.
Nicotine (Optional): Can range from 0mg to high levels depending on the user’s preference.
Flavoring: Food-grade flavor concentrates used to create different taste profiles.
What’s the Difference Between PG and VG?
PG is thinner and enhances the throat hit and flavor intensity, whereas VG is thicker and produces denser vapor clouds. Most vape juices have a blend of both to balance throat hit, flavor, and vapor production.
What Nicotine Strength Should I Choose?
Nicotine strength varies based on preference and previous smoking habits:
0mg (Nicotine-Free): For those who enjoy vaping without nicotine.
3mg - 6mg: Suitable for light smokers or those transitioning from smoking to vaping.
12mg - 18mg: Best for moderate smokers looking for a noticeable nicotine hit.
20mg+ (Nicotine Salt E-Liquids): Typically used in pod systems and for heavy smokers.
What Are Nicotine Salts?
Nicotine salts are a form of nicotine derived from tobacco leaves. They provide a smoother throat hit and allow for higher nicotine concentrations, making them ideal for those seeking a stronger nicotine experience without harshness.
Can Vape Liquid Expire?
Yes, vape liquid has a shelf life of about 1-2 years. Signs of expired e-liquid include:
Changes in color (darkening over time)
Separation of ingredients
Weakened or altered flavor
Reduced vapor production To prolong shelf life, store e-liquid in a cool, dark place away from direct sunlight.
What’s the Best Way to Store Vape Liquid?
To maintain quality and flavor, store your vape juice in:
A cool, dark place (e.g., a drawer or cupboard)
Airtight containers to prevent oxidation
Glass bottles instead of plastic if storing long-term
Why Does My Vape Juice Taste Burnt?
A burnt taste usually results from:
A worn-out coil that needs replacing
Dry hits due to lack of e-liquid in the wick
Vaping at too high of a wattage for your coil’s rating
Using high-VG juice in a device not designed for it
What’s the Best Type of Vape Juice for My Device?
Sub-ohm Tanks & High-Wattage Devices: High VG (70VG/30PG or 80VG/20PG) for dense vapor and smooth hits.
Pod Systems & Low-Wattage Devices: Higher PG or nicotine salts (50PG/50VG or 60PG/40VG) for stronger throat hits and quicker nicotine absorption.
Can I Mix Different Vape Liquids?
Yes, you can mix different vape liquids to create custom flavors, but ensure they have similar VG/PG ratios to maintain consistency in vapor production and performance.
Is There a Difference Between Freebase Nicotine and Nicotine Salts?
Yes:
Freebase Nicotine: More commonly used in standard e-liquids and delivers a stronger throat hit at higher concentrations.
Nicotine Salts: Smoother and absorbed faster, making them ideal for higher nicotine strengths and low-wattage pod systems.
Why Is My Vape Leaking?
Common reasons for leaking include:
Overfilling the tank
A damaged or improperly installed coil
Thin, high-PG e-liquid in a sub-ohm tank
A loose or faulty seal
Can I Make My Own Vape Liquid?
Yes, DIY e-liquid mixing is possible, but it requires careful handling of nicotine and precise measurements of ingredients. If you’re new to DIY mixing, start with small batches and follow safety guidelines.
Can I Vape Without Nicotine?
Yes! Many vapers enjoy vaping with 0mg nicotine juice purely for the flavors and vapor production.
What Are the Most Popular Vape Juice Flavors?
Popular flavor categories include:
Fruity: Strawberry, mango, watermelon
Dessert: Vanilla custard, cheesecake, cinnamon roll
Menthol: Mint, ice-cold fruit blends
Tobacco: Classic and sweet tobacco flavors
Candy: Gummy bears, sour belts, cotton candy
How Can I Tell If My Vape Juice Is High-Quality?
Look for:
A reputable brand with lab-tested ingredients
Clear labeling of VG/PG ratios and nicotine strength
No artificial or chemical aftertaste
Proper packaging and safety seals
Can I Travel With Vape Liquid?
Yes, but follow TSA and airline regulations:
Carry vape juice in 100ml bottles or smaller if bringing it in a carry-on
Store extra bottles in checked luggage
Be aware of local vaping laws at your destination
