Nicotine Strength Guide UK 2026: How to Choose the Right mg
Written by the Vape7Store UK Team — real vapers since 2024. Last updated: April 2026.
If you smoke 10 or more cigarettes a day, start with 20mg nic salt in a pod kit. If you smoke fewer than 10 a day, 10mg nic salt is usually the right level. If you have never smoked and are not switching, you should not vape at all. That is the short version of this guide.
Getting the nicotine strength right on your first vape is the single most important decision you will make as a new vaper. Too low and you will crave cigarettes and relapse. Too high and you will cough, feel dizzy, and give up. This guide walks you through what strengths are legally available in the UK, what each one is for, and how to match them to your smoking history.
All products referenced are TPD compliant, TRPR registered, MHRA notified, and for adults aged 18 and over only.
Nicotine Strengths Available in the UK
The UK legal maximum is 20mg per millilitre, set by Regulation 36 of the Tobacco and Related Products Regulations 2016. Anything advertised above 20mg in the UK is non-compliant. Here are the strengths you will actually find on the Vape7Store shelves:
- 0mg — Zero nicotine. For vapers who want the ritual and flavour but have finished reducing nicotine.
- 3mg — Freebase. For experienced sub-ohm vapers on high-powered mods.
- 6mg — Freebase. Light smokers or mid-range sub-ohm users.
- 10mg — Nic salt. Light-to-moderate smokers (under 15 a day).
- 12mg — Freebase. Rarely used now; legacy MTL option.
- 20mg — Nic salt. Heavy smokers, the default for ex-smokers in pod kits.
In 2026, the vast majority of UK pod kit users vape 20mg nic salt because it is the closest match to cigarette nicotine delivery the law permits.
Cigarettes Per Day vs Nicotine Strength
The table below is our team's working guide based on customer feedback and consistent advice from the NHS and Public Health England. These are starting points, not fixed rules — if the first strength you try feels wrong, you can step up or down.
| Cigarettes per day | Recommended nicotine strength | Recommended device type |
|---|---|---|
| 30+ | 20mg nic salt | Pod kit with 1.1Ω coil |
| 20 | 20mg nic salt | Pod kit (BM6000, NERA, Hayati) |
| 10–20 | 10mg or 20mg nic salt | Pod kit |
| 5–10 | 10mg nic salt | Compact pod kit |
| Under 5 | 10mg nic salt or 6mg freebase | Pod kit or MTL tank |
| Social smoker | 6mg freebase or 10mg salt | MTL tank |
| Quit attempt (reducing) | Step down: 20 → 10 → 6 → 3 → 0 | Any refillable |
What Strength for Heavy Smokers?
If you smoke 20 or more cigarettes a day and you want any serious chance of switching completely, you need 20mg nic salt in a pod kit. No exceptions. The NHS specifically notes that "you're roughly twice as likely to quit smoking if you use a nicotine vape compared with other nicotine replacement products" — but that statistic assumes you are getting enough nicotine. Under-dosing is the number one reason heavy smokers relapse in their first month of vaping.
Our team's most-recommended starter combo for a 20-a-day smoker:
- Device: Lost Mary BM6000 (£6.99 at Vape7Store)
- Strength: 20mg nic salt — comes pre-loaded in the pod
- Flavour to start: Watermelon Ice or Fresh Mint (both close to menthol cigarettes)
Find the full range at our Lost Mary BM6000 collection.
What Strength for Light Smokers?
If you smoke 5–10 cigarettes a day, 10mg nic salt is usually the sweet spot. It delivers enough nicotine to kill cravings without the throat punch of 20mg. Some light smokers find 20mg uncomfortable — dizziness, sore throat, hiccups. If that sounds like you, drop to 10mg and see how you feel after a week.
Light smokers often have more flexibility on device choice. Both pod kits and traditional MTL tanks work well at 10mg.
What Strength for People Who Want to Quit?
If your goal is to quit nicotine entirely, the best approach is a slow step-down. Start at the strength that fully controls your cravings (usually 20mg if you were a smoker), then reduce every 6–12 weeks:
- Weeks 1–12: 20mg nic salt — let your body adjust to vaping vs smoking
- Months 3–6: Drop to 10mg nic salt
- Months 6–9: Drop to 6mg freebase (requires switching from pod to MTL tank)
- Months 9–12: Drop to 3mg freebase
- Month 12+: 0mg for vaping without nicotine, or stop entirely
Do not rush this. Cancer Research UK confirms that nicotine itself is not the harmful part of smoking — the tar and combustion chemicals are — so staying on nicotine longer while fully off cigarettes is still an enormous health improvement. There is no prize for quitting nicotine in month six if it makes you relapse to smoking.
Nic Salt vs Freebase at Each Strength
The type of nicotine matters almost as much as the strength. At identical mg, nic salts feel much smoother. Here is a quick comparison of how each feels:
| Strength | Freebase feel | Nic salt feel |
|---|---|---|
| 3mg | Smooth, gentle throat hit | Not usually available |
| 6mg | Noticeable throat hit | Very smooth, gentle |
| 10mg | Strong throat hit, close to harsh | Smooth, satisfying |
| 12mg | Harsh in most devices | Smooth and comfortable |
| 20mg | Not legally sold in this form in the UK | Smooth — feels like 6mg freebase |

Can You Get Too Much Nicotine From Vaping?
In theory yes, in practice almost never. Your body has a built-in warning system: if you take in too much nicotine you will feel dizzy, nauseous, get a headache, and probably hiccup. This usually happens to new vapers in their first day because they chain-vape at 20mg like they would puff a cigarette — except a vape delivers nicotine continuously, not in 10 sharp puffs over 5 minutes.
The fix is simple: vape in small sessions, take shorter puffs, and wait longer between them. Your body will tell you when to stop. If you feel dizzy, put the vape down for 30 minutes.
For context, you would need to drink several millilitres of concentrated nic salt to reach genuinely dangerous levels, which is why UK law caps bottle sizes at 10ml and tank/pod sizes at 2ml — a deliberate safety measure under Regulation 36 of the TRPR.
Frequently Asked Questions
What nicotine strength should I start with if I smoke 20 cigarettes a day?
For a 20-a-day smoker, 20mg nic salt in a pod kit is the recommended starting strength. It delivers the nicotine level closest to a cigarette within UK legal limits and is the most effective at stopping cigarette cravings.
Is 20mg nic salt too strong for a beginner?
Not for a former cigarette smoker. 20mg nic salt is smooth at pod kit wattages and designed to match cigarette nicotine delivery. It is only too strong for people who were never heavy smokers.
What is the highest legal nicotine strength in the UK?
The highest legal nicotine strength in the UK is 20mg per ml, set under Regulation 36 of the Tobacco and Related Products Regulations 2016. Any e-liquid sold at higher strengths in the UK is non-compliant.
How do I know if my nicotine strength is too high?
Signs of too much nicotine include dizziness, headache, nausea, hiccups, and a racing heartbeat. If you feel any of these, stop vaping for 30 minutes and consider dropping to a lower strength.
Can I mix two different nicotine strengths?
Yes. Mixing a 10mg and a 20mg nic salt gives you roughly 15mg. This is a common way to fine-tune your strength, especially for people who find 20mg slightly too strong but 10mg too weak.
Does a higher mg mean more vapour?
No. Nicotine strength does not affect cloud size. Cloud size is determined by your device wattage and VG/PG ratio, not by how much nicotine is in the e-liquid.
Do I need to reduce my nicotine strength over time?
Only if you want to eventually stop vaping entirely. There is no health benefit to reducing nicotine if you have already quit smoking — Cancer Research UK confirms nicotine is not the harmful part of cigarettes. Stay on the strength that keeps you off tobacco.
Your Next Step
If you have read this far and you are ready to pick a kit, here is the short version: 10+ cigarettes a day means 20mg nic salt in a pod kit. Fewer than 10 a day means 10mg nic salt. Non-smokers should not vape. Everything else is refinement.
