There’s a lot of conflicting information about vaping online. Some claims are based on misunderstandings, while others come from confusing vaping with smoking or with products that don’t meet UK regulations.
For adult smokers and vapers, separating myths from facts can make the subject easier to understand.
Here are seven common vaping myths and a straightforward look at what’s behind them.
1. Myth: Vaping Is Just as Harmful as Smoking
Vaping and smoking are not the same thing.
Traditional cigarettes burn tobacco. This combustion process produces smoke containing many harmful chemicals.
Vape devices work differently. Instead of burning tobacco, they use a battery-powered coil to heat e-liquid and create an aerosol that is inhaled.
That doesn’t mean vaping is risk-free. Nicotine is addictive, and vaping products can carry health risks. However, the way a vape produces an aerosol is fundamentally different from the way a cigarette produces smoke.
The important distinction is simple:
Smoking burns tobacco. Vaping heats e-liquid.
2. Myth: Vapes Aren’t Regulated in the UK
Vaping products are regulated in the UK.
Nicotine-containing vaping products are subject to rules covering areas such as age restrictions, product capacity, nicotine concentration and product notification.
Some of the requirements consumers may recognise include:
- Nicotine-containing e-liquid refill bottles are limited to 10ml
- Vape tanks and cartridges are generally limited to 2ml
- Nicotine concentration is limited to 20mg/ml (2%)
- Nicotine vaping products must meet applicable notification requirements
- Selling nicotine-inhaling products to anyone under 18 is prohibited
These regulations are one reason legitimate products sold in the UK have specific packaging, warnings and product information.
Buying from a reputable retailer also helps reduce the risk of purchasing counterfeit or non-compliant products.
3. Myth: Vaping Causes Popcorn Lung
“Popcorn lung” is a nickname for a rare lung condition called bronchiolitis obliterans.
The vaping claim is usually linked to diacetyl, a chemical that has been associated with the condition following high levels of occupational exposure.
Diacetyl is prohibited as an ingredient in regulated nicotine-containing e-cigarettes and refill containers in the UK.
This is an important example of why it’s worth checking where vaping claims come from rather than relying on alarming headlines or social media posts.
Vaping is not risk-free, but the specific claim that regulated UK nicotine vapes cause “popcorn lung” because they contain diacetyl leaves out an important part of the picture: diacetyl is not permitted as an ingredient in these regulated products.
4. Myth: Vape Batteries Are Inherently Unsafe
Vape devices commonly use lithium-ion batteries—the same general battery technology found in many rechargeable electronic products.
Problems can occur when batteries are damaged, incorrectly handled, improperly charged or used with incompatible equipment.
That’s why battery care matters.
Use the correct charging equipment, follow the manufacturer’s instructions and avoid using a device or battery that appears damaged, swollen or unusually hot.
If your vape uses removable batteries, make sure you’re using the correct battery specification for the device.
The battery itself isn’t automatically unsafe simply because it is inside a vape. How the device and battery are designed, maintained and used matters.

5. Myth: All E-Liquids Are Basically the Same
E-liquids can look similar, but that doesn’t mean every bottle is identical.
Formulations can vary depending on the manufacturer, flavour, nicotine strength and intended device.
Common e-liquid ingredients can include:
Propylene Glycol (PG) – a thinner liquid commonly used as part of the e-liquid base.
Vegetable Glycerine (VG) – a thicker ingredient that contributes to aerosol production.
Flavourings – used to create different flavours.
Nicotine – included in nicotine-containing products at different concentrations.
Some e-liquids are also available without nicotine.
The PG/VG balance can affect how an e-liquid performs, so it’s important to use a liquid that’s suitable for your particular device.

6. Myth: E-Liquid Is Just Oil
This misunderstanding often comes from the word Vegetable Glycerine (VG).
VG can be derived from plant oils, but that doesn’t mean a bottle of e-liquid is simply filled with vegetable oil.
Typical vape e-liquids use ingredients such as PG and VG as their base, along with flavourings and, depending on the product, nicotine.
These ingredients are formulated specifically for use in compatible vaping devices.
This is also why you shouldn’t substitute ordinary household or cooking oils for e-liquid. Only use products specifically manufactured and intended for your vaping device.
7. Myth: You Can Drink E-Liquid
No. E-liquid should never be consumed as a drink.
E-liquid is designed for use inside a compatible vaping device, where it is heated by the coil.
Nicotine-containing e-liquid in particular can be harmful if swallowed and should be kept safely away from children and pets.
If e-liquid is accidentally swallowed, seek appropriate medical advice rather than waiting for symptoms to develop.
It’s also sensible to follow the handling and storage instructions provided with the product.
Why Vape Myths Spread So Easily
Vaping is a complicated subject because products, regulations and research continue to develop.
It’s also easy for information about cigarettes, illicit vaping products and regulated vaping products to become mixed together online.
A dramatic headline can then lose important context as it gets repeated across websites and social media.
When you come across a new claim about vaping, consider a few simple questions:
Where did the information come from? Is it referring to regulated UK products? Is there reliable evidence behind the claim? Is the information still current?
Checking the source can make a big difference.

The Quick Takeaway
You don’t have to believe every positive or negative claim you see about vaping.
The reality is usually more nuanced.
Vaping is not risk-free, and nicotine is addictive. At the same time, vaping works differently from smoking, UK nicotine vaping products are regulated, and some widely repeated vaping claims can be misleading or lack important context.
Understanding those differences is much more useful than relying on myths.
Final Thoughts
There’s plenty of information about vaping online, but not all of it tells the whole story.
Whether you’re researching devices, e-liquids or UK regulations, look for reliable and current information and be cautious about claims that sound overly simple or sensational.
And remember: vaping products containing nicotine are intended for adults. Nicotine is addictive.
