You’re standing in a shop staring at a shelf of pods. Maybe you’re fed up with paying a fortune for disposables. Or maybe you just want to quit smoking without feeling like you’re breathing in something mysterious. Either way, you’ve probably wondered: What Chemicals Are in Vapes? And honestly, you’re not alone. Most vapes contain four main things:
- Nicotine
- Propylene glycol (PG)
- Vegetable glycerine (VG)
- Food-grade flavourings
That’s it for the vast majority of devices. Whether it’s a simple pod like the Vaporesso Xros, a refillable tank, or even a cheap disposable, those are the usual suspects.
What Chemicals Are in Vapes?
1. Nicotine
Nicotine is the same stuff you get from cigarettes. But with vaping, you choose the strength that suits you. That control makes a huge difference. There are two types you’ll see:
- Freebase nicotine – older style, a bit harsher on the throat.
- Nicotine salts (nic salts) – smoother, used in things like Elf Bars and pods. Great for beginners.
Nicotine isn’t what creates smoke or tar. It creates the “craving” feeling, but not the burning damage you get from cigarettes.
2. Propylene Glycol (PG)
PG sounds scary because it’s got one of those sciencey names. But it’s basically a thin, clear liquid used in asthma inhalers and food products. Why do vapes use it?
- It carries flavour well.
- It gives you a stronger throat hit.
- It makes the vapour feel a bit like smoking.
If you’ve ever taken a puff and thought, “Oof, that one hits,” that’s the PG working.
3. Vegetable Glycerine (VG)
VG is thicker and sweeter than PG. It creates big vapour clouds. Why do you need it?
- It smooths out the vape.
- It stops it from feeling scratchy.
- It makes the vapour look dense.
High-VG liquids are popular for larger kits. Low-VG liquids are better for pods and nic salts.
4. Food-Grade Flavourings
This is the bit everyone talks about. Flavourings in vape juice are the same type used in sweets and drinks. The difference is that you’re breathing them in instead of eating them, so you want them to be safe and properly made. UK rules are strict. Brands have to test their liquids before selling them. If you’re buying from a proper UK shop like VapesDaddy, you’re covered.
What Chemicals Are in Vapes?
This part is important, especially if you’re switching from cigarettes. You won’t find:
- Tar
- Carbon monoxide
- Cigarette smoke
- 7,000+ burning chemicals
- Fibreglass
- Industrial oils
- Diacetyl (banned in the UK)
Most of the horror stories you see online come from untested, illegal products. Stick with known brands, and you avoid all that nonsense.
Why These Chemicals Are Used
Let’s keep it simple.
PG = carries flavour
VG = makes vapour
Nicotine = stops you climbing the walls
Flavourings = make it actually enjoyable
Together, they create a vapour that hits like a cigarette but with far fewer nasties. Think of it like making a cuppa:
- Water = VG
- Tea bag = PG with flavour
- Sugar = flavourings
- The kick of caffeine = nicotine
But Are These Chemicals Safe?
Nothing you breathe in is 100% harmless. Even standing by a busy road can’t be called “healthy.” But compared to cigarettes? Vaping is far less harmful, according to multiple UK health organisations. You’re removing the burning. And the burning is what creates the real danger in smoking. Most people switch from cigarettes because they notice:
- No more coughing
- Better senses of taste and smell
- Less wheezing
- More energy
- Less morning gunk in the throat
That alone tells you something.
What Chemicals Are in Vapes?
Disposables
Most disposables are used:
- Nic salt
- High PG/VG blend
- Strong flavourings
- A single-use coil and battery
Flavours tend to be punchy. Nicotine tends to be higher. The problem? Cost. Vaping something like a Vaporesso Xros 3 with bottled juice is way cheaper.
Pod Systems
Pods usually contain the same chemicals, but in a smoother mix. You’ll find:
- 50/50 PG/VG
- Nic salts
- Lighter flavours
These feel more like smoking. Perfect if you don’t want massive clouds.
Refillable Bottles (Shortfills & Nic Salts)
Shortfills (bigger bottles without nicotine) let you add your own “nic shot.” Nic salt bottles come ready to vape. Either way, the ingredients stay the same. You’re just getting more control and more value.
What About Nicotine Pouches?
If you’ve ever looked at things like Nordic Spirit or VELO, you’ll see a similar idea:
- Nicotine
- Flavourings
- Plant fibres to hold it together
No vapour. No PG. No VG. Just a pouch that sits under your lip. Some people use pouches at work and vape at home. A decent combo if you’re trying to cut down.
Common Myths About Vape Chemicals
Let’s knock out a few things you might have heard.
Vapes contain antifreeze.
PG can be used in antifreeze, but so can water. Doesn’t mean you’re drinking coolant.
Vape juice is full of metal
The liquid isn’t. Old coils can shed tiny particles, but modern kits are much better. Swap coils regularly, and you’re fine.
Vape chemicals stay in your lungs forever
Not true. PG and VG break down quickly.
Nicotine causes cancer
Nicotine is addictive. But the cancer risk from cigarettes comes from burning, not nicotine itself.
Should You Be Worried?
If you’re coming from smoking, vaping is almost always the easier, cheaper, and cleaner option. If you’ve never smoked, you don’t need nicotine at all. But if you’re using vaping to quit smoking, the chemicals in regulated UK vapes are far lower risk than cigarette smoke. Ask any long-time vaper. Most of us switched, noticed the difference within a week, and never looked back.
Final Verdict
If you want the truth about What Chemicals Are in Vapes, here it is:
- Most vapes use PG, VG, nicotine, and flavourings.
- UK rules keep out the nasty stuff.
- Pod kits and bottled liquids are cleaner and cheaper than disposables.
- If you want a simple switch, go for something like the Vaporesso Xros with a 10ml nic salt bottle.
- If you want a smokeless option, nicotine pouches work well.
