What Is Vaping and How Does It Work? A UK Beginner's Guide

What Is Vaping?

Vaping means inhaling an aerosol produced by an electronic device, often called a vape or e-cigarette. Instead of burning tobacco, the device heats e-liquid using a coil.

Most vape kits use these basic components:

• Battery: Powers the heating element.
• Tank or pod: Holds the e-liquid.
• Coil: Heats the e-liquid held in the wick.
• Mouthpiece: The part you inhale through.
• Button or airflow sensor: Activates the device, depending on the model.

If you are new to vaping, our vape kits collection includes different types of devices for different vaping styles.

How Does Vaping Work?

So, how does vaping work when you take a puff? The process happens within seconds:

1. You press the button or inhale, depending on the type of device.
2. The battery sends power to the coil.
3. The coil heats the e-liquid held in the wick.
4. The heated liquid forms an aerosol.
5. You inhale the aerosol through the mouthpiece.

In simple terms, the battery powers the coil, then it heats the e-liquid, and the resulting aerosol is inhaled.

With a refillable vape, the wick needs to stay soaked with e-liquid. Using a device with a dry wick can cause a burnt taste. This is why a new coil should be saturated with e-liquid before you start vaping.

What Is Vape Juice Made Of?

If you are asking what vape juice is, it is another name for e-liquid. Most e-liquids contain propylene glycol (PG), vegetable glycerine (VG), flavourings and, where included, nicotine.

Each ingredient has a different role:

• PG: Carries flavour and provides more throat hit.
• VG: Produces thicker aerosol and a smoother inhale.
• Flavourings: Give the e-liquid its taste.
• Nicotine: Provides nicotine in products that contain it.

E-liquids can also use different types of nicotine. Freebase nicotine generally provides more throat hit, while nicotine salts are usually smoother at higher strengths.

You can explore our e-liquids and nic salts to see the different options available.

How Do Different Vaping Styles Work?

Vaping style describes how you draw and inhale the aerosol. It can also affect the type of device, coil, and e-liquid you use.

• Mouth to lung (MTL): You draw the aerosol into your mouth before inhaling it into your lungs. The tighter draw can feel similar to smoking a cigarette.
• Restricted direct to lung (RDL): You inhale more aerosol than with MTL, but the airflow remains more restricted than a DTL setup.
• Direct to lung (DTL): You inhale the aerosol directly into your lungs. These setups usually have more airflow and produce more aerosol.

Nicotine strength is measured in mg/ml. The right strength depends on factors such as your previous smoking habit, device, and vaping style. Higher-powered DTL devices commonly use lower nicotine strengths than smaller MTL devices.

There is no single nicotine strength that suits every adult smoker. If you are using vaping to move away from cigarettes, a specialist vape shop or Stop Smoking Service can provide guidance.

What Types of Vapes Are Available?

Once you understand how a vape works, you will come across several types of devices.

The best type for an individual depends on their vaping needs, nicotine strength and preferred inhalation style.

What Are the UK Vaping Rules in 2026?

UK vaping regulations continue to change, so it is worth checking current guidance.

• Age restrictions: Nicotine vaping products cannot be sold to anyone under 18. From 29 October 2026, the age restriction will also cover nicotine-free vaping products.
• Single-use vapes: The sale and supply of single-use vapes have been banned across the UK since 1 June 2025.
• Nicotine limits: Nicotine-containing e-liquids are limited to 20mg/ml. Nicotine refill containers are limited to 10ml, while tanks and cartridges are limited to 2ml.
• Product notification: Regulated nicotine vaping products must meet the relevant requirements and be notified to the MHRA before they can be sold.
• Vaping Products Duty: From 1 October 2026, a new duty of £2.20 per 10ml will apply to vaping liquid, including nicotine-free liquid.

These rules apply alongside packaging, labelling and safety requirements for regulated products.

Is Vaping Safe?

Vaping is not risk-free. Nicotine is addictive, and the long-term effects of vaping are not yet fully known. However, the NHS states that nicotine vaping is less harmful than smoking because cigarette smoke contains many toxic substances produced by burning tobacco. For adult smokers who switch completely, vaping can reduce exposure to these harmful substances.

Non-smokers and young people should not start vaping. If you are using vaping to quit smoking, the NHS recommends eventually stopping vaping too once you are ready.

FAQs

What Is the Difference Between a Vape and an E-Cigarette?

The terms are often used interchangeably. E-cigarette is the broader term, while vape is the more common everyday term.

What Mistakes Should New Vapers Avoid?

Common mistakes include choosing the wrong nicotine strength, using unsuitable e-liquid, or vaping with a dry coil. Always follow your device instructions.

How does vaping work compared with smoking?

Smoking burns tobacco and creates smoke. Vaping heats e-liquid with a coil to produce an aerosol. Nothing is burned during the vaping process.

What nicotine strength should a beginner use?

It depends on your previous smoking habit, device,e and vaping style. Smaller MTL devices commonly use higher nicotine strengths than more powerful DTL devices.
