The Ultimate Guide to Vaping

What is Vaping? Vaping means inhaling vapour produced by an electronic cigarette (e-cigarette) or vape device instead of burning tobacco. Vapes heat a liquid (“e-liquid” or “juice”) to create a breathable aerosol. In other words, you’re inhaling vapour, not smoke.

Modern e-cigarettes are battery-powered devices that deliver nicotine (if present) via flavoured liquid. They do not contain tobacco, and so they produce none of the tar or many of the toxins of a cigarette.

This guide covers the basics about vaping: how devices and e-liquids work, why many smokers switch, current UK laws and trends, safety information and practical tips. Whether you’re curious about vaping as a quit aid or just want to know what all the buzz is about, we’ll walk through the essentials and answer common questions.

June 05, 2025 — By maff ali

Vape pods hit the market in 2017, revolutionising the vaping scene. Then came the era of disposables in 2020. But everything will change after the UK’s major vape ban on June 1st, 2025. Read on to discover what’s hot, what’s not, and what’s next.

Why Switch to Vaping?

Why Switch to Vaping

Discover the benefits of making the switch to vaping. From reduced harmful chemicals compared to traditional cigarettes to a wide variety of flavours, vaping offers a modern alternative that many adults are turning to for a cleaner experience.

A Great Alternative to Smoking

For example, the NHS states that “nicotine vaping is less harmful than smoking” and even calls it “one of the most effective tools for quitting smoking”. Cancer Research UK agrees that legal e-cigarettes “are far less harmful than smoking” and “can help people stop” smoking.

Further, ASH, an independent public health charity, points out, “smokers don’t die from exposure to nicotine, it's the chemicals in tobacco smoke that cause harm”. In practice, many smokers who switch to vaping find they cough less and feel better in the weeks and months afterwards (though some throat irritation or cough can occur initially).

What Else?

Besides health, cost and convenience are big factors. A UK smoker paying ~£16 for a pack of 20 is burning through about £4,000–5,500 a year (ASH Scotland calculates ~£5,569/yr for an average pack-a-day habit). In contrast, even a regular vaper might spend only a few hundred pounds a year. A basic vape starter kit costs maybe £10–£20 up front, plus the cost of coils (≈£10/month) and e-liquid (≈£15/month). In practice, most vapers end up paying far less than they did for cigarettes. (If health didn’t convince you, perhaps saving thousands of pounds each year will!)

It’s Odourless!

Vaping also fits many people’s lifestyles better. There’s no ash and no lingering stale smoke smell on clothes or in your home. Vapour dissipates quickly, so you’re not blowing thick smoke everywhere (though etiquette still matters around non-vapers).

Overall, if you’re a smoker looking to quit or cut down, UK health bodies say vaping is a far better alternative than staying with cigarettes.

What Are Hybrid E-Liquids?

The idea of vapour-based nicotine delivery has been around for a long time. As early as 1927, a patent was filed in the US for a basic “vaporiser” device. But it wasn’t until much later that the concept took off. For decades, it remained an idea — one that couldn’t quite beat the dominance of traditional cigarettes.

Hybrid E-Liquids

The Breakthrough in 2003

Modern vaping began in 2003, thanks to Chinese pharmacist Hon Lik. After losing his father to lung cancer, he set out to create a less harmful alternative to smoking. What he came up with was the first truly viable electronic cigarette — a small device that delivered nicotine via heated vapour instead of smoke. It was a personal solution, but it didn’t stay personal for long.

The Breakthrough in 2003

2004: The First E-Cigs Hit the Market

By 2004, Hon Lik’s invention was already being sold in Chinese pharmacies. Not long after, it quietly made its way to Europe and the US. In the UK, early adopters started spotting them in odd corners of high streets. Around 2007, these were usually sold in tiny shops between takeaway joints and betting shops. The devices were known as "cigalikes," and they looked almost exactly like cigarettes.

2007: Cigalikes

These first-generation devices were designed to feel like smoking. But they had their downsides. Battery life was short, vapour was weak, and the flavour didn’t impress. They used disposable cartridges you’d toss when empty. Still, they helped many smokers take the first step away from tobacco.

2010: The Rise of Vape Pens and Tank Kits

Soon after, vape pens began to take over. These were slightly bigger devices with refillable tanks and replaceable coils. The experience improved dramatically — better battery life, stronger vapour, and a wider range of flavours. Vape pens were still easy to use, but offered a more satisfying vape. For many, this was the moment vaping stopped feeling like a novelty and started to feel like a real alternative.

2013: Enter the Box Mod

By the mid-2010s, box mods arrived on the scene. These were larger, customisable devices that delivered massive clouds and intense flavour. Vapers could adjust power settings, change airflow, and swap out coils — even build their own. It was a big leap from cigalikes, but for hobbyists, this level of control was the appeal. Box mods weren’t for everyone, but they pushed the limits of what vaping could do.

The Breakthrough in 2003

2015: A Turning Point

In 2015, Public Health England released a report stating that vaping is “around 95% less harmful than smoking.” That line was quoted everywhere. It didn’t end all debate, but it gave vaping credibility, especially as a tool for smoking cessation. The narrative began to shift: vaping wasn’t just a gadget; it had public health potential.

2017: The Pod Kit Boom

Between 2018 and 2020, pod systems took over. Sleek, compact, and almost foolproof, pod kits used pre-filled or refillable pods, often with nicotine salt e-liquids. They were popular because they were simple: no buttons, no settings — just inhale. Pod systems made vaping more accessible than ever, especially for smokers looking for an easy switch.

2020: The Disposable Explosion

Disposables surged in popularity soon after. Colourful, lightweight, and pre-filled, they required no maintenance — just puff and go. Brands like Elf Bar and Geek Bar became household names. Walk down any high street by 2021 and you’d see them everywher

The Shift

The big new change in 2025 is the ban on disposable vapes. From 1 June 2025, it will be illegal across England, Scotland and Wales to sell or supply any single-use, non-refillable disposable vape – even if it has no nicotine. This ban was introduced mainly as an environmental measure (millions of disposable vapes were being tossed as litter) and also to control youth uptake (cheap disposables helped fuel the recent teen vaping surge).

The Parliament’s Role

Aside from the disposables ban, more laws are on the horizon. The Tobacco and Vapes Bill (introduced late 2024) would give the UK government more powers to minimise or control youth vaping – for example, banning any vape advertising aimed at under-18s, and enabling plain or restricted packaging for e-liquid.

It even proposes a “smoke-free generation” (a phased ban on selling tobacco to people born after a certain year). But these changes are still pending. For now, the main legal points for vapers in 2025 are: 18+ only, products must meet EU-derived safety limits (≤2 ml tank, ≤20 mg nicotine, etc), and no single-use vapes from June 1, 2025.

Current Vaping Trends in the UK

Why Switch to Vaping

Vaping is now a mainstream behaviour in the UK, with prevalence continuing to rise among both former and current smokers. According to ASH’s 2024 report, about 11% of UK adults — that’s roughly 5.6 million people — are current vapers. That’s the highest it’s ever been. More people now vape than smoke.

Most vapers aren’t new to nicotine. In fact, 53% of them are ex-smokers. That stat alone suggests vaping’s playing a big role in helping people quit cigarettes. Around 32% of current smokers also vape, meaning a third of them are (kind of halfway) out the door

On the other end, you’ve got the non-smokers - only about 1.6% of them vape regularly. So the narrative that vaping is attracting a generation of non-smokers might be a bit overstated, at least when it comes to adults.

Popular Vapes & Flavours in the UK

Device use among UK vapers shows a clear preference for refillable devices. As of 2024, approximately 53% of adult vapers report using a refillable tank or pod device as their primary setup. These systems allow for customisation, are more cost-effective over time, and appeal to users seeking flexibility in nicotine strength and flavour. However, the popularity of disposable vapes has increased incredibly in recent years. In 2021, only 7% of vapers reported using disposables; by 2024, that figure rose to 30%. Among adults aged 18 to 24, usage is even higher, with 52% identifying disposables as their usual device. This trend is largely attributed to their ease of use and low upfront cost, factors that continue to drive uptake among younger demographics. Refillable vape devices offer greater customisation and long-term cost efficiency. Users can select their preferred nicotine strength, experiment with a wide range of flavours, and typically spend less over time compared to those using single-use disposables. While disposables are convenient, refillable systems are better suited for users seeking sustained use, flavour variety, or gradual nicotine reduction.

Hybrid E-Liquids

Flavour preferences among UK vapers continue to be dominated by fruit profiles. According to ASH’s 2024 survey, approximately 47% of adult vapers primarily use fruit-flavoured e-liquids. In comparison, menthol/mint flavours account for around 17%, while tobacco flavours represent 16%. Dessert and confectionery-style flavours remain less common among adults but are somewhat more prevalent among younger users. Among under-18 vapers, 59% report preferring fruit flavours, with sweet or dessert-like options ranking second in popularity.

Hybrid E-Liquids

Vaping's Influence on Youth

Youth uptake of vaping remains a central concern. It gets a lot of attention, and for good reason. The ASH youth survey (11–17-year-olds) says about 7.2% of British teens currently vape — that’s 390,000 kids. Compared to the 5.1% who smoke, vaping is ahead now. But context matters. Most of those young vapers aren’t daily users. A big chunk (about 76% of non-smoking youth) say they’ve only tried it once or twice. Curiosity is the biggest driver. Not an addiction. Not yet, anyway. To sum it all up, roughly 1 in 9 British adults vape. Smoking rates keep falling. Refillable devices still dominate, but disposables rose in popularity, especially with younger users. Flavours are fun, fruit-forward, and controversial depending on who you ask. And youth vaping is rising, though everyone’s keeping a very close eye on it.

What is in a Vape & How Does a Vape Work

Why Switch to Vaping

Every e-cigarette (no matter the shape) has the same basic parts. It consists of a mouthpiece, battery and cartridge or tank containing the nicotine solution. The common components are:

  • Battery: This is the power source. It may be built into the device or a separate cell you insert. Batteries come in various sizes (e.g. 18350, 18650, 21700 are common formats for larger mods) or as a small 400–1000 mAh pack in pod kits. The battery charges via USB or replaceable cells and powers the coil. Some devices are button-activated, while many are “auto-draw”.
  • Atomiser / Coil: The coil (or “atomiser head”) is a small metal unit that contains a coil of wire and a cotton wick. When you inhale the vape, the battery heats the coil, which vaporises the e-liquid absorbed in the wick. Coils have different resistances (measured in ohms): low-ohm coils vaporise liquid quickly and make lots of vapour (for DTL), while high-ohm coils give a tighter draw (for MTL). Coils need replacing regularly (typically every 1–2 weeks with heavy use) because the wick degrades.
  • Tank or Cartridge: This holds the e-liquid. Tanks (or clearomizers) are usually refillable reservoirs made of glass or plastic that screw onto the device. Some kits use small cartridges or “pods” that you fill or swap out. The tank feeds liquid to the coil via the wick. You fill the tank with e-liquid through a fill port (some devices have top-fill or bottom-fill designs).
  • Mouthpiece (Drip Tip): This is the tip you draw from. It sits at the top of the tank or pod. Drip tips can be wider for DTL devices or narrower for MTL. Some tanks allow changing the drip tip for comfort or airflow reasons.
  • Other parts: Many modern vapes also include: an airflow control (a ring or slider to increase/decrease air entering the tank), controls or screen (on mods, to set power), and safety features (overheat protection, short-circuit protection, etc).

Understanding Vaping Styles

There’s more than one way to inhale from a vape. Your “vaping style”, as it is commonly referred to, depends on your preference and how much vapour you want filling your lungs (or not).

Here’s a breakdown of the three vaping styles:

Mouth-to-Lung (MTL)

This one’s the most cigarette-like. You draw the vapour into your mouth first, then breathe it into your lungs, just like how you’d smoke a cig. It's sharp, deliberate, and gives a nice throat hit. MTL is common in beginner kits and lower-power devices. It’s where most people start, and honestly, it just feels familiar if you're quitting smoking.

Hybrid E-Liquids

2. Direct-to-Lung (DTL)

DTL is inhaling vapour straight into your lungs, like taking a big, deep breath. You’ll need a device with open airflow and a bit more power. Sub-ohm coils are common here (they create big, dense clouds). It’s smooth and kind of theatrical. You’ll recognise it right away if you’ve seen someone blow massive clouds; it was probably DTL. But it’s not for everyone. Some people love it, while others might feel like they’re choking on a fog machine.

3. Restricted Direct-to-Lung (RDL or RDTL)

This style of vaping is a bit of an in-between. You still inhale straight into your lungs, but the airflow’s tighter. The result is more flavour than MTL, but less air than DTL. You get a warm, dense hit without going full cloud-chaser. Some pod kits let you tweak the airflow to find your RDL sweet spot.

Hybrid E-Liquids

Which One Should You Choose?

If you’re new, MTL is the usual first stop. It’s smoother, less intense, and gives you time to figure things out. Later on, you might fancy more vapour or want to try new flavours. That’s when people start switching to RDL or DTL setups. Your vaping style influences what kind of device and coil you’ll need. But once you know whether you prefer a tight, cigarette-like draw or a lungful of fruity fog, things get much easier

Types of Vape Kits

Why Switch to Vaping

Vape devices come in many forms, and this is one of the reasons vaping has such a broad appeal. Vaping devices typically fall into the following categories:

  • Cig-a-likes: These are battery-powered, cigarette-sized devices, operated by 90mAh to 280mAh lithium-ion batteries, which provide a constant voltage of about 3.7V. They possess pre-filled cartomisers with resistances of 2.2 to 3.0 ohms and capacity for 0.5ml to 1.0ml of e-liquid, with nicotine strengths between 12mg/ml and 24mg/ml. They are draw-activated and meant to be simple, with small vapour production and battery life.
  • Pod Kits / Vape Pens: Pod kits and vape pens use larger rechargeable batteries, usually ranging from 400mAh to over 1500mAh. Pod systems use refillable or pre-filled pods with coils, with or without replaceable coils. Vape pens use a refillable tank with replaceable coil heads and with fixed or variable wattage. Both deliver well-balanced vapour production, simple-to-use design, and are popular with mouth-to-lung (MTL) consumers and beginners due to their simplicity.
  • Box Mods: Mods are advanced vaping devices with big internal or replaceable batteries. They support large, adjustable wattage or voltage control, usually through digital means, and allow sub-ohm coils (usually below 1.0 ohm) for dense vapour output. Mods are tank compatible and allow full control over power levels, coil setups, and airflow. Designed for direct-to-lung (DTL) vaping, they deliver strong vapour and flavour.
  • Disposable Vapes: Disposable vapes consist of single-unit, non-refillable units pre-filled with e-liquid and charged for immediate use. They typically contain 1.5ml to 2ml of liquid and a small internal battery, typically between 280mAh and 1000mAh. Single-use only, they do not require filling, charging, or maintenance and are triggered on inhalation. While popular because of their convenience, especially for youth and new users, they are being taken off the UK's shelves, with a single-use vape ban across the UK taking effect on June 1, 2025.
  • Specialised Kits: Specialised kits include modern devices such as rebuildable atomisers (RBAs, RDAs, RTAs), in which the user can build and install their preferred coils to gain total control of performance.

E-Liquids Explained

Why Switch to Vaping

Vapers inhale a mix of vapour and flavour from a liquid known as e-liquid or vape juice. The basic ingredients of e-liquids are food-grade Vegetable Glycerin (VG) and Propylene Glycol (PG), plus flavourings, and usually nicotine. Both VG and PG are commonly used in food and are considered safe to consume by major health authorities, like the FDA in the U.S. and EFSA in the EU, as long as they're used in the right amounts.

  • Vapers inhale a mix of vapour and flavour from a liquid known as e-liquid or vape juice.

Both VG and PG are commonly used in food and are considered safe to consume by major health authorities, like the FDA in the U.S. and EFSA in the EU, as long as they're used in the right amounts.
  • VG (Vegetable Glycerin): A thick, sweet liquid that produces dense vapour clouds. Higher VG ratios give big clouds and a smoother throat feel. VG carries sweet/dessert flavours well (like candy or custard).
  • PG (Propylene Glycol): A thinner liquid that delivers flavour more strongly and gives a stronger “throat hit” (kind of a tingling sensation in the throat). Higher PG ratios make the vape feel more similar to smoking and work well with menthol or tobacco flavours.
  • Nicotine: E-liquids usually contain freebase nicotine (the same type as cigarettes) or nicotine salts. Nicotine salt e-liquids allow higher nicotine strength with a smoother inhale, so many pod systems use them (e.g. 20 mg salt can feel like a mild 12 mg freebase). Freebase nicotine comes in strengths from 0 mg up to the UK limit of 20 mg/ml. (Legally, UK vape liquids cannot exceed 20 mg/ml due to EU-derived rules.)
  • Flavours: Thousands of flavours exist. Popular categories include fruit (berry, citrus, melon), dessert/sweets (vanilla custard, chocolate, cake), menthol/mint, and traditional tobacco. The UK market is very rich in variety. Many vapers find switching flavours each week keeps vaping interesting and helps reduce cravings.
  • Note: Most e-liquids are a blend of VG and PG (common ratios are 50/50, 70VG/30PG, etc). Pod systems often use high-PG salt e-liquids for a cigarette-like hit, while cloud-chasing mods might use 80VG/20PG mixes. Find a balance you like: more VG for vapor, more PG for throat hit.

Types of E-Liquid

Why Switch to Vaping

E-liquids come in a few types. Here’s what sets them apart:

Freebase Nicotine

Traditional nicotine was used in early vape juice. Offers a stronger throat hit at higher strengths — good for low-wattage devices and ex-smokers.

Nicotine Salts (Nic Salts)

Smoother, faster-absorbing nicotine. Ideal for higher strengths (like 10–20 mg) without the harshness. Great for pod kits and anyone looking for a satisfying vape without the sting.

Bar Salts

A newer twist on nic salts, designed to mimic the intense flavour of disposable vapes. Super sweet, bold, and perfect for those switching from throwaway vapes to refillables.

Shortfills

Big bottles with no nicotine — usually 50 ml or more, with room to add your own nic shot. Perfect for sub-ohm vapers or anyone who wants control over their nicotine level.

Be aware (Note):  Nicotine is addictive, so a safer approach is to start with enough nicotine to satisfy cravings (so you don’t relapse to cigarettes), then gradually reduce according to your preference. Apart from buying store-bought e-liquids from a store, you can also create your own liquid at home. Let’s explore the steps and details of DIY liquid in the next section.

E Liquid Calculator

Making your own e-liquid can put you in full control of your flavour experience. As opposed to store-bought e-liquids, you can not only choose the nicotine strength that suits you, but also the PG and VG ratio that matches your vaping style, and how bold or subtle you want your flavours to be.

How to start?

Once you’ve got all your ingredients, you need to do a bit maths. For example, calculate the VG/PG ratio, determine the nicotine strength, and so on. That’s obviously time-consuming, especially if you aren’t a math wizard.

Good news?

With e-liquid calculators, you can do the calculation in just a few seconds. Just put the information, like VG/PG ratios, nicotine strengths, etc., to get your recipe.

Here is your e-liquid calculator:

How to Use the DIY E Liquid Calculator?

It’s easy. Follow the steps and instructions to use an e liquid mixing calculator:

Set the batch size

Enter the total amound of e-liquid you want to make, in millilitres.

Choose your nicotine level

Enter the strength of nicotine you want in the final mix (mg per ml).

Pick your PG/VG ratio

Adjust the balance between Propylene Glycol (PG) and Vegetable Glycerin (VG) using the slider. This affects the throat hit, the amount of vapour, and the flavour.

Add your flavours

  • Say what percentage of the total mix it should be.
  • Specify if it’s PG or VG-based, as this will change the overall PG/VG balance.

Get your recipe

After entering all details, the calculator will show you how much of each ingredient to use, both in millilitres and grams.

Mix it up

Check your recipe, measure everything carefully, and mix as per the results of the e liquid calculator. Handle nicotine and other ingredients with care.

How to Use a Vape?

If you’re ready to start vaping, you might be feeling a bit unsure about where to begin. Whether you're a smoker trying to make the switch or just someone curious about vaping, getting the basics right can make all the difference. Here’s a simple guide to help you start vaping:

Hybrid E-Liquids
  • Choose a Starter Device: For most new vapers, a basic pod kit or vape pen is ideal. Look for something small and easy (many kits come ready to go with a built-in battery and either a refillable pod or pre-filled pods). Avoid diving straight into a complex box mod. Start simple. Popular beginner devices include those with refillable pods or small tanks.
  • PG (Propylene Glycol): A thinner liquid that delivers flavour more strongly and gives a stronger “throat hit” (kind of a tingling sensation in the throat). Higher PG ratios make the vape feel more similar to smoking and work well with menthol or tobacco flavours.
  • Charge It Up: Fully charge the battery before first use (usually via USB). Read the manual: if it has buttons, hold the power button or press it to turn it on. If it’s draw-activated (no button), make sure it’s charged and ready.
  • Fill or Insert E-Liquid: If your device uses refillable pods or tanks, fill it with e-liquid up to the recommended line (don’t overfill). Let it sit a minute so the coil can soak up liquid (this is called “priming the coil”). If using pre-filled pods or disposables, they’ll come loaded. Pick an initial nicotine strength similar to your smoking level (see nicotine note above).
  • Take Your First Vapes: If it’s draw-activated, just inhale through the mouthpiece. If it is a button-activated device, press the fire button as you inhale. Start with gentle, 2–3 second draws into your mouth, then breathe in (MTL style). You might cough a little at first (this is normal) – try slower draws or a slightly lower nicotine if it’s harsh. You’ll notice the vapour and flavours immediately; many find the throat hit satisfies the nicotine craving similarly to smoke.
  • Adjust as Needed: If the vapour is too thin or the flavour is weak, you might need a more powerful device or a higher VG liquid. If the throat hit is too strong (making you cough), try a bit lower nicotine or more PG. If you taste burnt cotton (“dry hit”), take a break and add a bit more e-liquid. Experiment until it feels comfortable.
  • Maintenance: Change coils regularly (every 1–2 weeks for heavy use) to avoid a burnt taste. Keep the tank at least 1/4 full (running completely dry can burn the coil). Clean the tank once in a while (rinse with warm water, dry fully). Always turn off (or lock) your device when not using it to avoid accidental firing.

Vaping Mistakes to Avoid

Why Switch to Vaping

Here are some of the most common mistakes new vapers make and how you can avoid them:

  • Too Low Nicotine: If a heavy smoker switches to a low-strength (e.g. 3 mg) e-liquid, they may find it unsatisfying and might relapse. Conversely, too high nicotine (20 mg) on a large mod can feel overwhelming. Start around 12–18 mg if you were a moderate-to-heavy smoker, or around 6–12 mg if light smoker.
  • Battery Safety: Only use the charger that came with your device. Don’t leave charging unattended overnight (modern devices do cut off, but it’s safer not to test limits).
  • Improper Use: Don’t blow into the device (it can flood the coil). Don’t store it upside-down (liquid can leak out). And never use oils not meant for inhalation (stick to purpose-made e-liquids).
  • Trial and Comfort: Starting vaping is mostly about trial and comfort. If the first flavour or kit doesn’t click, try another one as there’s a lot of choice. Many shops will let you sniff or sample flavours. Over time, as long as you use the device regularly, you’ll get the hang of the inhalation rhythm. Most importantly, keep cigarettes out of reach as consistency helps vaping take over the routine.

Debunking Common Vaping Myths

There’s no shortage of misinformation when it comes to vaping. So, let’s set the record straight and take a closer look at some of the most common myths, with facts from trusted UK sources:

Hybrid E-Liquids
  • “Vaping is just as bad as smoking.” No. UK experts repeatedly emphasise that vaping is substantially less harmful than smoking. Biomarker studies show vapers have much lower exposure to the toxic chemicals of smoke. PHE’s review found around 95% fewer harms in vaping compared to smoking. Many studies confirm that vaping removes tar and carbon monoxide completely (two main killers in cigarettes). It’s true that inhaling any substance isn’t 100% safe, but relative to cigarettes, e-cigs are far safer.
  • “Nicotine in vapes causes cancer or kills you.” No. Nicotine itself is addictive, but it isn’t the main cause of smoking-related diseases. As ASH explains, smokers “don’t die from exposure to nicotine” – it’s the tar and other combustion chemicals that cause cancer, heart and lung damage. Studies show no evidence that vaping causes cancer. In short, nicotine withdrawal causes cravings, but switching to vaping eliminates the deadly smoke cocktail.
  • “Vape fumes are just secondhand smoke in disguise.” Vaping produces visible vapours, and these vapours are much cleaner than cigarette smoke. UKHSA reports there’s no significant risk from others breathing vape mist in the short term. Vapes don’t emit carbon monoxide or most carcinogens. The aerosol mainly contains VG/PG (which dissipates quickly), tiny nicotine residue (can linger on surfaces in heavy use), and trace flavourings. Current evidence says passive vaping is far less harmful than passive smoking, though most people still avoid vaping right next to non-vapers.
  • “Kids vaping will lead to a new generation of smokers.” Concerns about the gateway from vaping to cigarettes have been studied closely. UK data do not show a large gateway effect. In fact, a PHE review found that “almost all” of the 2.6 million adult vapers were current or ex-smokers, and “very few” non-smokers became regular vapers (less than 1% in surveys). Among teenagers, most vaping occurs in those who have already tried smoking, or who only experiment occasionally. If anything, youth smoking rates have continued to fall as vaping has risen. The great majority of 11–17 year-olds have never vaped at all, and 98% of non-smoking teens are not vaping.
  • “Vapes explode or cause popcorn lung.” Exploding vape batteries make sensational headlines, but they’re extremely rare and almost always due to misuse (like using chargers or batteries incorrectly). Modern regulated batteries and mods have safety mechanisms in place. Follow basic battery care to avoid issues. As for “popcorn lung” (bronchiolitis obliterans), it was linked to the buttery flavour chemical diacetyl in early e-liquids. Almost all responsible e-liquid makers now avoid diacetyl and similar chemicals. There is no confirmed case of a vaper developing “popcorn lung”. Throat or mouth irritation can occur for new vapers (common with high-PG liquids or cold air), but genuine lung disease from vaping in humans hasn’t been observed in the available evidence.

Wrapping Up

Both improved vape regulations and high-quality ingredients have advanced to minimise risks. UK health bodies agree that, relative to cigarettes, vaping is much safer. As one public information video put it, “smokers who use e-cigarettes and get support have the highest quit rates”. So don’t let scary stories distract you. If you’re switching from cigarettes, vaping is likely significantly better for your health.

Vaping Glossary

Whether you’re completely new to vaping or simply brushing up on the terminology, the jargon can seem a bit technical at first. Here’s a clear and concise guide to some of the most common vaping terms you’re likely to come across:

  • Atomiser/Coil: The heating element (wire + wick) inside your vape that vaporises e-liquid. Think of it as the “heart” of the device – it needs to be replaced every 1–2 weeks.
  • Battery: The power source (built-in or removable cells) that heats the coil. Varies from small (pod kit battery) to large (18650/21700 cells in mods).
  • Tank/Clearomiser: A refillable chamber that holds e-liquid. It screws onto the battery. Tanks often have a glass window.
  • Pod: A small cartridge that may be pre-filled or refillable. Modern pod kits use pods instead of larger tanks.
  • Drip Tip: The mouthpiece you breathe through. Comes in different shapes (narrow for MTL, wide for DTL).
  • Mod: Short for “modification.” A customisable vaping device (usually box-shaped) with adjustable power. Also called an advanced vaporiser.
  • Cig-a-like: Early e-cig resembling a cigarette, often disposable or using replaceable mini cartridges.
  • PG/VG (Propylene Glycol / Vegetable Glycerin): Base liquids in e-juice. PG carries flavour and gives a throat hit; VG creates thicker clouds.
  • Nic Salts (Nicotine Salts): A type of nicotine in e-liquid that absorbs smoothly at higher strengths. Often used in pod devices.
  • RTA/RDA: (Rebuildable Tank/Dripping Atomiser) For hobbyists who build their own coils. Not needed for beginners.

  • Sub-ohm: Using a coil with resistance less than 1Ω for big clouds (common in DTL).

Vaping FAQs

Answers to common questions about vaping safety, laws, usage, and quitting.

Q: Is vaping safe?

Vaping is far safer than smoking tobacco. Health agencies stress that switching to vaping reduces harm significantly. However, because e-cigs are relatively new, long-term effects are still being studied. If you’re a smoker, the advice is that vaping is much better than continuing to smoke.

Q: Can I vape anywhere?

There is no UK law strictly banning vaping in public (unlike smoking in enclosed public places), but many venues follow smoke-free rules. Many workplaces, pubs and transport companies now request no vaping indoors (for courtesy). You cannot vape on aeroplanes or in UK hospitals by default, as they follow strict no-smoking rules. Don’t blow vapour in someone’s face. Legally, you can vape in parks or open pubs at the owner’s discretion.

Q: How do I choose nicotine strength?

Base it on your smoking habit. If you smoked a pack a day, try 12–20 mg/ml to start. If you were light (a few a day), try 6–12 mg. Nicotine salts, as compared to freebase nicotine, can hit faster. It’s best to avoid guessing too low and ending up unsatisfied (which risks going back to cigarettes). You can always ease down the strength over time.

Q: Will vaping keep me addicted to nicotine?

If you use nicotine-containing e-liquid, yes, you’re still using nicotine, which is addictive. But remember that the biggest addiction factor in smoking is nicotine, plus the behavioural habit of lighting up and inhaling smoke. Vaping lets you get off the deadly smoke. Many people eventually reduce the nicotine percentage in their vape (or quit it) once they are comfortable with vapes.

Q: Is vaping legal?

Yes, for adults. You can legally buy vape products (nicotine or zero-nicotine) only if you are 18+. Just follow the laws when it comes to age (18+), nicotine strength (20mg/ml max) and e-liquid limits (2ml per pod, 10ml per e-liquid bottle max). It’s legal to use vapes in private and public places where smoking is allowed (subject to any venue rules). Check local regulations if you travel (some countries ban vaping entirely).

Q: What about e-liquid spills or storage?

E-liquid with nicotine is an irritant and could be harmful if swallowed or absorbed through the skin. Keep e-liquid bottles away from children and pets. Wash your hands if you spill it. Store e-juice in a cool, dark place as sunlight can degrade nicotine and flavour. Empty pods/cartridges and disposable vapes should be recycled if possible (there are UK recycling points for electronics and batteries).

Q: Can ex-smokers switch back?

Some ex-smokers who vape eventually stop vaping, too. There’s no requirement to continue vaping forever. The aim for many is to quit cigarettes, and then gradually reduce nicotine until they don’t need it. The best outcome is quitting smoking; vaping may be temporary. Even if you keep vaping long-term, experts say your health is still much better than if you had gone back to smoking.

Q: What if I want to stop vaping completely?

Treat it like quitting any nicotine product. You can step down strength or use nicotine replacement if needed. Because vaping is more controllable, quitting is often easier once you’re only vaping and not smoking. Support is available, as many stop-smoking services now include vape guidance.

Q: Are there side effects of vaping?

Some vapers report dry mouth, coughing, or headache, especially at first. These usually lessen over days or weeks. Make sure to drink water (nicotine is a mild diuretic). If you get a rash or nausea from a specific flavour or high nicotine, try a different one. Switching from cigarettes to vaping generally improves lung function and reduces chest tightness over time.

Q: Who can I trust for help or products?

In the UK, buy from reputable and responsible vape shops like Greet Vape or pharmacies. Ask shop staff for advice on kits and e-liquid. Websites with clear company info and MHRA-registered vapes are best. Beware of cheap, unbranded products online (some may be mislabelled). If you’re under medical supervision, tell your doctor you’re vaping to quit smoking, as you will find many GPs and clinics support that choice.

Remember

Vaping is primarily intended as an aid to quit or reduce smoking. For smokers, it is widely considered far less harmful than cigarettes. If used properly, it can save lives and money. As Public Health England put it, smokers who switch “have the highest quit rates”. We hope this beginner’s guide to vaping helps you understand how to vape and navigate vaping with confidence and correct information. Stay safe, and vape responsibly!
