1. What Is Vaping?

Vaping is the process of inhaling aerosol (vapour) produced when an e-liquid is heated by a battery-powered device. Unlike cigarettes, vaping does not involve combustion — there is no burning tobacco, no tar, and no carbon monoxide.

E-cigarettes and vape devices work by heating a liquid (called e-liquid or vape juice) that typically contains:

• Propylene glycol (PG)
• Vegetable glycerine (VG)
• Flavourings
• Nicotine (optional)

Public Health England (now UK Health Security Agency) famously stated that vaping is approximately 95% less harmful than smoking. It is the UK's most popular smoking cessation tool, with over 4.5 million adults currently vaping in Britain.

2. How Does Vaping Work?

Every vape device — from the simplest disposable to a professional sub-ohm mod — works on the same basic principle:

1. Battery — powers the device
2. Coil — a metal heating element (usually Kanthal, stainless steel, or mesh) that heats up when the battery fires
3. Wick — usually cotton, absorbs e-liquid from the tank or pod
4. E-liquid — drawn onto the wick and vaporised by the coil
5. Vapour — inhaled by the user through the mouthpiece

When you press the fire button (or inhale on a draw-activated device), the battery sends power to the coil. The coil heats instantly, vaporising the e-liquid soaked into the wick. You inhale the resulting vapour.

3. Types of Vape Devices

Choosing the right device is the most important decision for a new vaper. Here are the main types available in the UK in 2026:

Disposable Vapes

Best for: Absolute beginners, casual vapers, trying new flavours

Disposable vapes are pre-filled, sealed, single-use devices requiring zero setup. In the UK, TPD-compliant disposables contain 2ml of e-liquid at up to 20mg nicotine salt, delivering approximately 600 puffs. Simply open, vape, and responsibly recycle at a WEEE collection point when finished.

Popular UK options: SKE Crystal Bar, Lost Mary BM600, Elf Bar 600, Geek Bar

Key facts: No charging, no refilling, no coil changes. The most accessible entry point into vaping.

Pod Kits (Closed System)

Best for: Beginners wanting reusability, ex-smokers

Pod kits use pre-filled or refillable pods that click into a rechargeable battery. They are compact, discreet, and simple to use. Most support nic salt e-liquids for a satisfying nicotine delivery similar to cigarettes.

Pod Mods (Open System)

Best for: Intermediate vapers wanting more control

Refillable pod mods give you freedom to fill with any compatible e-liquid. They offer adjustable wattage, replaceable coils, and longer battery life than basic pod kits.

Vape Pens

Best for: Vapers who want simplicity with more battery capacity

Slim, pen-shaped devices with a tank and replaceable coils. Easy to use, relatively affordable, and widely available across the UK.

Box Mods / Sub-Ohm Kits

Best for: Experienced vapers, cloud chasers

Powerful devices with extensive customisation — variable wattage, temperature control, and compatibility with a wide range of sub-ohm tanks and coils. Use with high-VG shortfill e-liquids for maximum vapour production.

4. The Complete E-Liquid Guide

E-liquid (also called vape juice or e-juice) is the fluid that is vaporised in your device. In the UK, there are three main formats:

10ml TPD E-Liquids (Nic Salts & Freebase)

All nicotine-containing e-liquids in the UK are sold in 10ml bottles, regulated under the Tobacco Products Directive. They are available in freebase nicotine or nicotine salt formats in strengths of 3mg, 6mg, 10mg, and 20mg.

Shortfill E-Liquids (50ml / 60ml / 100ml)

Shortfills are nicotine-free e-liquids sold in large bottles (typically 100ml) with space left to add a 10ml nicotine shot. They are not subject to the same 10ml bottle restriction as nicotine e-liquids, making them excellent value. Add one 10ml 18mg nic shot to a 100ml shortfill to achieve a 3mg finished e-liquid.

Nicotine Shots (Nic Shots / Boosters)

Concentrated 10ml bottles of pure nicotine base (typically 18mg) designed to be added to shortfill bottles. Available in 50/50, 70VG/30PG, and 80VG/20PG blends.

5. Nicotine Strengths Explained

Choosing the right nicotine strength is critical — too low and you will not get satisfaction; too high and it will be harsh or overwhelming.

Nicotine Strength	Best For	Equivalent Smoking Level
0mg (nicotine-free)	Ex-vapers stepping down, flavour chasers	Not applicable
3mg	Light smokers, sub-ohm vapers	Very light / social smoker
6mg	Light to moderate smokers	Under 10 cigarettes per day
10mg (nic salt)	Moderate smokers switching	10–15 cigarettes per day
20mg (nic salt)	Heavy smokers, immediate switchers	20+ cigarettes per day

Rule of thumb: If you smoke a full pack (20 cigarettes) daily, start with 20mg nic salt. If you smoke fewer than 10 a day, try 10mg or 6mg. You can always adjust.

6. Nic Salts vs Freebase Nicotine

This is one of the most common questions from new UK vapers.

Freebase Nicotine

• The traditional form of nicotine in e-liquids
• Stronger throat hit, especially at higher strengths
• Best in 3mg–6mg for sub-ohm devices
• Slower absorption than nic salts

Nicotine Salts

• Uses benzoic acid for smoother, faster nicotine absorption
• Closely mimics the nicotine delivery of a cigarette
• Available in 10mg and 20mg (max legal UK strength)
• Smooth throat hit even at 20mg
• Best in low-power MTL pod devices
• Recommended for ex-smokers

Verdict: If you are switching from cigarettes, choose nic salts in a pod device. If you are an experienced vaper using a sub-ohm kit, choose freebase 3mg shortfill.

7. VG/PG Ratios — What Do They Mean?

Every e-liquid contains a blend of Vegetable Glycerine (VG) and Propylene Glycol (PG). This ratio affects throat hit, cloud production, and flavour intensity.

Ratio	Throat Hit	Cloud	Flavour	Best For
50VG/50PG	Strong	Light	Intense	MTL pods, starter kits
70VG/30PG	Moderate	Dense	Good	Sub-ohm kits, shortfills
80VG/20PG	Smooth	Very dense	Moderate	Advanced sub-ohm

8. UK Vaping Laws & TPD Regulations 2026

The UK regulates vaping under the Tobacco and Related Products Regulations 2016 (implementing the EU Tobacco Products Directive, retained post-Brexit). Key rules:

• Age restriction: You must be 18 or over to purchase vaping products in the UK
• Nicotine limit: Maximum 20mg/ml nicotine in any e-liquid
• Tank/bottle size: Maximum 2ml for nicotine-containing tanks; maximum 10ml for nicotine e-liquid bottles
• MHRA registration: All nicotine-containing products must be notified to the MHRA before sale
• Advertising restrictions: Nicotine products cannot be advertised on TV, radio, print, or most online channels
• Disposal: Disposable vapes must be recycled at WEEE collection points — not general waste

All products sold at Absolute Vape UK are fully TPD compliant and MHRA registered.

9. Is Vaping Safe? UK Health Authority Guidance

No form of nicotine consumption is entirely risk-free, but the UK health establishment has reached a clear consensus:

• UK Health Security Agency (UKHSA): Vaping is approximately 95% less harmful than smoking
• NHS: Recommends vaping as a smoking cessation tool and actively supports its use in Stop Smoking services
• Cancer Research UK: States that e-cigarettes are far less harmful than smoking
• Royal College of Physicians: Supports vaping as a harm reduction strategy

Important: Vaping is intended for adult smokers switching from cigarettes. It is not recommended for non-smokers, pregnant women, young people, or individuals with certain heart or lung conditions.

10. How to Switch from Smoking to Vaping

Making the switch successfully comes down to three things: the right device, the right nicotine strength, and the right flavour.

Step 1: Choose Your Device

For most smokers, a pod kit or disposable vape is the best starting point. These devices deliver nicotine quickly and feel closest to the draw of a cigarette.

Step 2: Match Your Nicotine Strength

• Heavy smoker (20+ a day): 20mg nic salt
• Moderate smoker (10–20 a day): 10mg–20mg nic salt
• Light smoker (under 10 a day): 6mg–10mg

Step 3: Pick Your Flavour

Flavour is personal — but research consistently shows that ex-smokers who enjoy their e-liquid flavour are more likely to stay vaping and away from cigarettes. Try menthol, tobacco, or fruit flavours to start.

Step 4: Commit for at Least 2 Weeks

Most smokers feel the full benefit of vaping after 2–4 weeks. The first few days can be an adjustment — stick with it.

12. Vaping FAQs — Answered by the Absolute Vape Team

Is vaping allowed indoors in the UK?

UK law does not ban indoor vaping in public places (unlike smoking), but individual businesses and venues set their own policies. Many workplaces, restaurants, and public transport operators prohibit vaping indoors. Always check venue rules before vaping.

Can I vape on a plane?

No. Vaping is prohibited on all commercial flights. E-cigarettes must be carried in hand luggage (not checked bags) due to battery regulations. Check the vaping laws of your destination country before travelling.

How do I know when my vape coil needs replacing?

Signs your coil needs replacing include: a burnt taste, reduced vapour production, leaking, or a gurgling sound. Most coils last 1–2 weeks depending on usage. Using sweet, high-VG e-liquids shortens coil life.

What is the cheapest way to vape in the UK?

The most cost-effective approach is a refillable pod device with 10ml nic salt e-liquids or a sub-ohm kit with 100ml shortfill e-liquids. Disposable vapes are convenient but more expensive per puff than refillable alternatives.

Are there nicotine-free vapes available?

Yes. All 100ml shortfill e-liquids contain 0mg nicotine by default. Many brands also produce 0mg versions of their 10ml e-liquids. Zero nicotine vaping allows you to enjoy flavour and the physical habit without nicotine.

How do I store e-liquid?

Store e-liquid in a cool, dark place away from direct sunlight and heat. Keep bottles tightly sealed. Properly stored e-liquid has a shelf life of 1–2 years. Always keep e-liquids out of reach of children and pets.

What is TPD compliance?

TPD (Tobacco Products Directive) compliance means a vaping product has been tested and registered with the UK's Medicines and Healthcare products Regulatory Agency (MHRA). All nicotine-containing products sold legally in the UK must be TPD compliant. Every product at Absolute Vape UK meets this standard.
