Switching from cigarettes to vaping is one of the biggest changes many smokers make. Choosing the right vape kit matters, but choosing the correct nicotine strength can make an even bigger difference.
If your nicotine level is too low, you may continue craving cigarettes. If it's too high, you might experience dizziness, headaches or an overly harsh throat hit. The good news is that finding the right nicotine strength is much easier once you understand how different vape nicotine levels work.
Quick Answer: What Strength Should You Start On?
Match your strength to how much you smoked. Light smokers (under 5 a day) do well on 3mg freebase or 5mg nic salt; moderate smokers (around 10 a day) on 6mg freebase or 10mg nic salt; and heavy smokers (15–20+ a day) usually need 20mg nic salt — the UK legal maximum. When in doubt, nic salts in a refillable MTL pod kit give the closest feel to a cigarette.
Why Choosing the Right Nicotine Strength Matters
Many people believe buying a vape is enough to quit smoking. In reality, nicotine strength plays a much bigger role than most beginners realise. The NHS advises using a nicotine strength that's high enough to manage cravings, as choosing the wrong strength can make switching from cigarettes more difficult.
The correct nicotine strength can help you:
- Control cigarette cravings
- Reduce withdrawal symptoms
- Feel satisfied after fewer puffs
- Avoid returning to smoking
- Transition comfortably to vaping
What Do Vape Nicotine Strengths Mean?
In the UK, nicotine strength is measured in milligrams per millilitre (mg/ml) — for example 3mg, 5mg, 10mg or 20mg. UK law limits nicotine-containing e-liquids to a maximum of 20mg/ml, so this is the strongest e-liquid you can legally buy.
Nicotine Strength Chart for Ex-Smokers
Your starting strength is usually based on how many cigarettes you smoked each day. This isn't an exact rule, but it's a useful starting point — everyone absorbs nicotine differently, so you may make small adjustments in the first few weeks.
| You smoked | Nic salt | Freebase | Best setup |
|---|---|---|---|
| Light – under 5/day | 5mg | 3mg | Any MTL pod kit |
| Moderate – around 10/day | 10mg | 6mg | Refillable MTL pod kit |
| Heavy – 15–20+/day | 20mg | – | Refillable MTL pod kit + nic salts |
If you were a light smoker
If you smoked fewer than five cigarettes each day, you usually won't need the highest nicotine strength. Most light smokers find that 3mg freebase or 5mg nic salt provides enough satisfaction without being overpowering.
If you were a moderate smoker
People who smoked around half a pack each day generally feel comfortable using 10mg nic salt or 6mg freebase. These provide a balance between smooth flavour and satisfying nicotine delivery.
If you were a heavy smoker
If you regularly smoked 15 to 20 cigarettes or more each day, starting too low often leads to stronger cravings. Most heavy smokers begin with 20mg nic salt for the fastest, most satisfying hit.
Common Mistakes People Make After Switching
Starting with nicotine that's too low
Many smokers worry about higher strengths and choose 3mg straight away. For someone who smoked a pack a day, this is often too low and leads to stronger cravings — and a higher chance of relapse.
Using an old or burnt pod
Your vape replacement pod has a direct impact on flavour, vapour and nicotine delivery. As pods wear out they produce less vapour, mute the flavour, deliver nicotine less effectively and can create burnt or dry hits.
Using the wrong device
Not all vape kits suit high-strength nicotine. High-powered sub-ohm devices are better with lower strengths, while refillable pod kits are ideal for nic salts and smokers making the switch. Choosing the right combination of device, pod and e-liquid makes vaping far more satisfying.
Expert Tips for Choosing the Right Strength
- Match your nicotine strength to your previous smoking habits.
- Don't choose the lowest strength simply because it sounds healthier.
- Use nicotine salts if you're new to vaping.
- Replace your vape pods regularly for the best flavour.
- Give yourself a week or two before deciding whether your level is right.
- Reduce nicotine gradually rather than making large jumps.
- Stay hydrated, as vaping can occasionally cause a dry mouth.
Refillable vs Prefilled Starter Kits
Refillable starter kits let you fill the pod with your preferred nic salt or 50/50 e-liquid and replace the pod or coil when needed. They offer lower long-term costs, a wider choice of flavours, more strength options and less waste. For smokers using 10mg or 20mg nic salts, a refillable mouth-to-lung (MTL) pod kit gives the closest experience to a cigarette.
Prefilled starter kits are all about convenience — insert a compatible pod and start vaping with no manual refilling. They're ideal for people completely new to vaping, those who prefer minimal maintenance, or anyone wanting a simple replacement for disposable vapes.
Best Starter Kits for Beginners
| Kit | Type | Price |
|---|---|---|
| Prefilled pod kit | £11.99 | |
| Refillable bundle | £19.99 | |
| Prefilled pod kit | £6.99 | |
| Prefilled pod kit | £12.99 | |
| Refillable pod kit | £12.49 | |
| Refillable pod kit | £9.99 |
The refillable options (Hexus Go, Vaporesso XROS 4 Mini and Geekvape Sonder Q2) are the closest match to a cigarette when paired with 10–20mg nic salts, while the prefilled kits (Hayati, Elf Bar, IVG) are the easiest step across from disposables. Browse the full range of starter kits to compare.
Frequently Asked Questions
What nicotine strength is best for quitting smoking?
For many smokers, 10mg or 20mg nicotine salts provide enough satisfaction to replace cigarettes comfortably. The ideal strength depends on how much you previously smoked.
Is 20mg nicotine legal in the UK?
Yes. Under UK regulations, 20mg/ml is the maximum nicotine strength permitted in consumer e-liquids.
Should I choose nic salts or freebase nicotine?
Nicotine salts are generally recommended for new vapers because they provide a smoother inhale and faster nicotine satisfaction.
Can I reduce my nicotine strength over time?
Yes. Many former smokers gradually reduce their nicotine level once they no longer experience strong cravings.
How often should I replace my vape pod?
It depends on how frequently you vape and the e-liquid you use. Most replacement pods last between one and two weeks before flavour and performance begin to decline.
Does a burnt pod affect nicotine delivery?
Yes. A worn or burnt pod can reduce vapour production and flavour, making your vape feel less satisfying even if you're using the correct nicotine strength.
Final Thoughts
Switching from cigarettes to vaping isn't just about choosing a device — it's about finding the combination that works best for you. The right nicotine strength can reduce cravings and make your vape more satisfying, while a well-maintained refillable pod kit and fresh replacement pods ensure the best flavour and performance every day. Everyone's experience is different, so give yourself time to find what feels right.
