Vaping 101: The Ultimate Beginner’s Guide

Every day, thousands of people ditch cigarettes or throw away their last disposable and go looking for something better.

The problem is, the internet hands you a wall of jargon and a hundred conflicting opinions.

This guide cuts through all of it. I’ve been testing and writing about vaping for over 15 years, and what you’re reading now is the version I wish existed when I started. Whether you’re coming off smokes or just tired of binning £5 disposables every three days, this is where you begin.

Why People Switch From Smoking (And From Disposables)

The two biggest entry points into proper vaping are ex-smokers and people who’ve been running on disposables.

Both groups have different needs, but they share one goal: they want something that actually works without costing a fortune.

For ex-smokers, the appeal is simple. Vaping delivers nicotine without the tar, combustion, and the smell that follows you everywhere.

Public Health England’s much-cited report estimate put vaping at around 95% less harmful than smoking, and while that figure gets debated, the consensus among health bodies is consistent: switching is a meaningful harm reduction step.

For the disposable crowd, the maths does the talking. Single-use disposables like the Lost Mary BM600 and Elf Bar were banned in the UK in June 2025, pushed out by legislation targeting their environmental impact and appeal to underage users.

The industry’s answer was prefilled pod devices, which deliver the same convenience and flavour but with a swappable pod instead of a binnable device.

The cost, unfortunately, stayed roughly the same: £5-8 per pod is the going rate, which means your weekly spend barely moves.

A refillable pod kit with a bottle of nic salt changes that equation entirely. Same upfront cost, far lower ongoing spend.

The other thing both groups get wrong is thinking they need to go straight to complicated gear.

You don’t.

The best starter vape is almost always a simple pod kit, and that’s exactly where this guide starts.

Types of Vape Devices: What’s Actually Out There

Before you spend a penny, it helps to know what you’re choosing between. Here’s a no-nonsense breakdown of the main device types:

Device Type	Who It’s For	Our Picks
Pod kits	Ex-smokers, people leaving disposables	Best Pod Vapes Right Now
MTL mods	Smokers wanting a tighter draw	Best MTL Vape Kits
Disposables	Absolute beginners, backup devices	Best Disposable Vapes
Prefilled pods	People who want disposable convenience in a refillable form	Best Prefilled Vapes
Boro vapes	Experienced vapers who want maximum flavour control	Boro Vapes Explained

• Pod kits are the sweet spot for most beginners. They’re compact, they use nicotine salt e-liquid, and the draw feels close to a cigarette. Devices like the Vaporesso XROS series and OXVA Xlim are consistently the ones I point people toward first.
• MTL mods give you more battery and tank capacity but require a bit more setup. Think of them as pod kits for people who want to grow into vaping rather than just dabble.
• Prefilled pods sit somewhere between disposables and refillable kits. You swap out the pod rather than refilling it, which removes the mess but keeps the convenience. They cost a bit more per pod than buying e-liquid in bulk, but they’re genuinely foolproof.

Fun Fact: The world’s first modern e-cigarette was patented in 2003 by Chinese pharmacist Hon Lik. He developed it after his father died of lung cancer from smoking. The irony of a pharmacist inventing vaping is not lost on me.

Understanding Nicotine Strength

This is where most beginners get it wrong, and where most vape shops give terrible advice.

• Get your nicotine strength right, and vaping will feel satisfying from day one.
• Get it wrong, and you’ll either feel nothing or feel sick.

Here’s the straightforward version:

Your Smoking Habit	Format	Strength	Shop
Light (under 10/day)	Nic salt	10mg	Browse Nic Salts
Medium (10-20/day)	Nic salt	20mg	Browse 20mg Nic Salts
Heavy (20+/day)	Bar salt	20mg	Browse Bar Salts
Cost-conscious	Longfill	20mg	Browse Longfills

The key distinction is between freebase nicotine (the old-school kind in most e-liquids) and nicotine salts.

Nic salts use benzoic acid to create a smoother hit at higher strengths, which is why they pair so well with pod kits.

You get a satisfying nicotine hit at 10mg or 20mg without the harsh throat burn you’d get from freebase at those levels.

If you’re a heavy smoker, don’t start at 10mg. You’ll crave more and end up reaching for cigarettes.

Start at 20mg, get comfortable, and step down later if you want to.

Nic Salts vs Bar Salts vs Freebase: Which One Do You Actually Need?

Three formats dominate the UK vape juice market right now. Here’s how they differ, and where each one makes sense.

• Nic salts (10ml bottles) are what most pod kit users buy. They come in thousands of flavours, cost around £2-4 per bottle, and are the closest thing to disposable-grade flavour in a refillable format. If you’re switching from an Elf Bar or Lost Mary, this is your first stop.
• Bar salts (60ml-100ml bottles) deliver that same disposable-style sweetness but in larger volumes with a lower cost per ml. They’re designed to taste like the disposables people know and love. If you’ve been buying disposables purely for the flavour profile, bar salts are the direct replacement.
• Freebase e-liquid is for sub-ohm devices (higher wattage, bigger clouds). It comes in bigger bottles (50ml-120ml shortfills and longfills), uses lower nicotine strengths (3mg-6mg), and produces significantly more vapour. Not the right starting point for most beginners, but worth knowing about for later.

Hate tiny 10ml bottles? You’re not alone. Here’s the solution for UK vapers: Why Longfills Make More Sense

Format	Bottle Size	Cost Per ML (approx.)	Best For	Shop
10ml Nic Salt	10ml	~62p/ml	Trying flavours, pod kits	Browse
20ml Nic Salt	20ml	~35p/ml	Regular pod vapers	Browse
Shortfill + shot	50ml	~28p/ml	Sub-ohm/cloud fans	—
60ml Longfill	60ml	~23p/ml	Pod users buying in bulk	Browse
120ml Longfill	120ml	~15p/ml	Heavy vapers	Browse

Shortfills, Longfills, and the UK Vape Tax (What You Need to Know Now)

This section matters more than most beginner guides will admit, because the UK vape tax is coming in October 2026 and it will change how you buy e-liquid.

Here’s the quick version: the UK government is introducing an excise duty on vaping products.

• The Vaping Products Duty lands at a flat rate of 22 pence per ml on all vaping liquid.
• That means a 10ml bottle picks up £2.20 in duty on top of its retail price.
• Even a 2ml prefilled pod adds 44p.

It’s not catastrophic on a single purchase, but across a month of vaping it adds up fast.

• Shortfills are 50ml or 100ml bottles that come with space for a nicotine shot. You buy the flavoured base at 0mg, drop in a nic shot, shake, and you’re done. No 10ml limit, no nicotine tax on the base.
• Longfills work the same way but in even larger volumes (60ml-120ml). The cost per ml drops significantly, and you’re future-proofing yourself against the incoming tax hike.

• Shortfill vs Quickmix vs Longfill Explained
• Best Longfill E-Liquid UK
• Buy 60ml/120ml Nic Salts in Bulk

If you’re a heavy vaper buying 10ml bottles every few days, switching to longfills now is one of the most practical moves you can make.

Fun Fact: The UK vaping market is worth an estimated £1.3 billion per year. Despite the incoming tax, Britain still has one of the most progressive harm-reduction frameworks for vaping in the world, with the NHS actively recommending it as a cessation tool.

Best Vape for Beginners: What I’d Actually Recommend

Let’s be straight here. There is no single “best vape” for everyone. But there are clear winners depending on your situation.

You Are…	Best Device Type	Our Pick
Just quit smoking	MTL pod kit	Best MTL Vapes
Coming off disposables	Refillable pod kit	Best Pod Vapes
On a tight budget	Prefilled pod	Best Prefilled Vapes
Want more vapour/clouds	DTL kit	Best Vapes Overall

My personal go-to recommendation for most people starting out is the Vaporesso XROS series. They’re compact, reliable, and the coils last 4-6 weeks between changes, and they don’t leak. Simple as that.

Read the Vaporesso XROS 5 Review for an overview of the best value option.

And check out the Vaporesso XROS Pro 2 for a slightly more advanced version with more battery and slightly more power.

The OXVA Xlim Pro 2 DNA is another one I point people toward constantly. It uses the same refillable pod system but with slightly more airflow options, which suits people who want a fractionally less tight draw than a cigarette.

For juice pairing: What Vape Juice Should I Use With My Pod?

The one thing I’d tell any beginner: don’t overthink it.

A £25 pod kit and a couple of bottles of 20mg nic salt will tell you everything you need to know about whether vaping works for you.

You don’t need to spend £80 on a mod to find out.

How To Use a Vape (And How to Fix Common Problems)

Setting up a pod kit takes about two minutes. Fill the pod, wait five minutes for the coil to prime, then take a few gentle puffs.

That’s genuinely it for most devices.

Where beginners run into problems is almost always one of these four things:

1. Burnt taste This is a dry hit. It means your coil didn’t have enough liquid on it, or you puffed too fast. Prime the coil properly, wait longer between puffs, and keep the pod at least a quarter full. Full breakdown here: Why Your Vape Tastes Burnt

2. Pod dying early Chain vaping, using high-VG juice in a pod designed for nic salts, or just getting a dud coil. All fixable. Why Your Pod Keeps Dying Early

3. Leaking Some pods are more prone than others. Fill from the side (not the centre), don’t overfill, and keep the device upright when not in use. If yours leaks constantly, it might just be the wrong device. Pod Vapes That Don’t Leak

4. Flavour not as good as a disposable This is a real thing and it’s worth addressing. Most people compare their pod flavour to a disposable and feel shortchanged. The gap is real, but it’s closeable. How to Get Disposable-Grade Flavour From a Pod Kit

Wrapping Up

Vaping doesn’t need to be complicated. Start with a pod kit, use 20mg nic salts if you’re a moderate-to-heavy smoker, and give it a week before you judge whether it’s working.

Most people who bounce back to cigarettes do so in the first 72 hours before the nicotine delivery starts to feel natural.

The kit, the juice, the strength — all of that can be refined. But you won’t know what refinements you need until you’ve got a baseline to work from.

Start simple, get comfortable, then explore from there.
