Vaping has become super popular. But have you ever stopped to think about what’s actually in vape juice? If you're using something like Elux Nic Salts or bar juice salt, it's smart to know what you're putting in your device—and into your body.

This guide breaks down what’s inside vape juice in the simplest way possible.

What Is Vape Juice and Why Do People Use It?

Vape juice, also called e-liquid, is the stuff that turns into vapour when you use a vape. It's what makes the flavours, clouds, and sometimes gives that hit of nicotine.

People vape for different reasons:

• Some want to quit smoking.
• Others enjoy the flavours and the chill experience.
• Some just like blowing clouds (let’s be honest, it looks cool).

Whatever your reason, it all starts with the juice.

The Main Ingredients in Vape Juice

Almost all vape juices use the same basic ingredients. There are usually four:

• PG (Propylene Glycol)
• VG (Vegetable Glycerin)
• Flavourings
• Nicotine (optional)

Let’s break each one down in plain English.

Propylene Glycol (PG): Carries the Flavour

PG is a thin, clear liquid. It’s used in food and medicine too. In vape juice, it’s there to carry flavour.

• PG makes the vape taste strong.
• It gives a little "throat hit"—like smoking.
• Less vapour, more flavour.

If you like sharp flavours or want that classic smoking feel, go for a vape juice with more PG.

Vegetable Glycerin (VG): Makes Big Clouds

VG is thicker and sweeter than PG. It’s also found in lots of food products. In vape juice, VG is what creates those big clouds of vapour.

• More VG = more vapour.
• It feels smooth and soft when you inhale.
• Slightly sweet on its own.

If you're all about the clouds, look for juices with high VG. They’re perfect for sub-ohm vapes and cloud chasers.

Flavourings: The Fun Part

This is where it gets tasty. Flavourings make vaping fun. Think watermelon, cola, menthol, or even dessert-like tastes. Some vapes taste just like sweets or drinks.

Good brands like bar juice salt use food-grade flavourings that are safe to inhale. Poor quality juices might taste off or even burn your throat. So always buy from trusted names.

Nicotine: Optional but Powerful

Not all vape juices have nicotine, but many do. It’s the part that helps smokers switch to vaping. Nicotine comes in different strengths—usually from 3mg to 20mg.

Elux Nic Salts, for example, use “nicotine salts” instead of regular nicotine. These give a smoother hit even at high strengths. That means you get the buzz without the harshness.

New to vaping? Start with a low or medium nicotine level. Heavy smoker switching to vape? Nic salts can help.

What Should You Look For in a Good Vape Juice?

Picking the right vape juice isn’t just about flavour. You should always check a few things:

• Ingredients on the label – Make sure it clearly lists PG, VG, and nicotine.
• Nicotine strength – Choose what’s right for your needs.
• Clear packaging – Trusted brands label their bottles properly.
• Childproof caps – Keep kids safe.
• No weird smells or colours – If it looks or smells wrong, don’t use it.

When in doubt, go for well-known brands. You’re better off paying a little more for quality than risking your health with a cheap liquid.

Is Vape Juice Safe?

No vape juice is 100% risk-free. But using proper, tested products is much safer than using random ones.

Authorities like Public Health England say that vaping is far less harmful than smoking. Still, it’s best to avoid dodgy, unlabelled juices or those with unknown chemicals.

Stick with known products like Elux Nic Salts and bar juice salt, and always buy from trusted stores.

How to Store Vape Juice the Right Way

Even vape juice needs some care. Here’s how to keep it fresh:

• Store in a cool, dark place – Heat and light can ruin the liquid.
• Keep away from kids and pets – Nicotine can be dangerous if swallowed.
• Don’t use old juice – Most bottles have expiry dates.

If your vape juice smells weird or tastes off, it’s probably time to throw it out.

Final Thoughts: What’s in Your Vape Matters

Knowing what’s inside your vape juice helps you make smarter choices. PG gives you flavour. VG gives you clouds. Nicotine gives you that buzz (if you want it). And flavourings? They bring the fun.

When you choose trusted brands like Elux Nic Salts or bar juice salt, you get safe, tasty, and satisfying juice that works well with your device.

Vaping should feel good—not confusing or risky. So next time you shop, read the label, pick what fits your style, and enjoy every puff.
