When people start vaping, they often hear the terms PG and VG. These letters may seem confusing, but they are super important in the vaping world. PG means Propylene Glycol. VG means Vegetable Glycerin. Both are used in e-liquids — the liquid you put into a vape. But they do different things.
Let’s break it all down in simple words.
Introduction to PG and VG in E-Liquids
E-liquid is like the “juice” your vape needs to work. It often comes in small bottles and includes flavour, sometimes nicotine, and the base — which is made up of PG, VG, or both. Think of PG and VG like the water in squash. Without it, there would be no way to vape.
PG and VG are safe ingredients used in food and medicine too. They help carry flavours and make the clouds you see when someone exhales.
What is Propylene Glycol (PG)?
Propylene Glycol is a clear, runny liquid. It doesn’t have a taste or smell. PG is good at carrying flavour. That means e-liquids with more PG usually have a strong taste. PG also gives you that “throat hit,” which some ex-smokers like because it feels like smoking a real cigarette.
Some people may find PG too strong or irritating, especially if they have sensitive throats. That’s why it’s important to try a small amount first.
What is Vegetable Glycerin (VG)?
Vegetable Glycerin is thicker and a bit sweet. VG makes those big clouds you see when people vape. It gives a smoother feeling when you inhale. E-liquids with high VG are popular among cloud chasers — people who like to blow big vapour clouds.
VG is also gentle on the throat. But since it’s thick, it may not work well in all vape devices. It can also sometimes dull the flavour a little bit.
Key Differences Between PG and VG
Here’s what makes them different. PG is thinner, stronger in flavour, and gives more throat hit. VG is thicker, smoother, and makes more vapour. That’s the simple way to look at it.
Some vapers like a mix of both. For example, a 50/50 mix gives a balance between taste and vapour. Others prefer more VG for smoother clouds. If you want stronger taste and throat feel, more PG is better.
Which is Better: PG or VG for Your Vaping Style?
The best choice depends on what kind of vaping experience you want. If you are just quitting smoking, PG might feel more familiar. If you care about smoothness or big clouds, VG will be your friend.
Some brands offer both. One great option is elux Nic salt, which usually comes in a smooth blend that works for beginners and experienced users alike. These e-liquids help deliver flavour without making the throat feel harsh.
Another option is Bar Juice 5000, a well-known brand that offers a range of fruity and sweet flavours. Their liquids also come in different PG/VG blends, so you can choose what feels right for you.
Common Uses and Blends of PG and VG in E-Liquids
Most vape juices are not 100% PG or VG. Instead, they are blended. A common mix is 70/30 or 50/50. A 70/30 VG/PG blend gives thick clouds and a smooth puff. A 70/30 PG/VG blend will hit the throat more and deliver strong flavour.
Nicotine salt e-liquids often use a balanced PG/VG blend. These are perfect for small vape devices and people who want a quick hit of nicotine without a harsh feeling.
If you’re unsure which to pick, start with a 50/50 blend. Then you can change later based on what you like more.
Health and Safety Considerations When Choosing PG vs. VG
Both PG and VG are considered safe by health experts when used in e-liquids. They are also used in cough syrup, toothpaste, and even food. But everyone is different. Some people might get dry mouth or a sore throat with high PG liquids. VG, being thicker, may clog up smaller vape devices over time.
Always buy your e-liquids from trusted brands. Cheap liquids can sometimes have poor ingredients. And remember to drink water when vaping — it helps your throat stay happy.

Conclusion
PG and VG may sound confusing, but they’re easy to understand once you know what they do. PG is all about flavour and feel. VG is all about clouds and smoothness. Most vapers use a mix of both, based on what feels right.
Choosing the right e-liquid can make vaping much better. Whether you want a big cloud or a strong taste, now you know how to find the perfect match.
