Nicotine Strength Guide: What Level Should You Vape?

Picking the wrong nicotine strength is the main reason new vapers give up in the first week. Too high and you feel sick after three puffs. Too low and you are buying cigarettes again by lunchtime.

The short answer: if you smoke 10 or more cigarettes a day, start at 20mg nicotine salt in a pod kit. If you smoke fewer than 10, start at 10mg. If you are already vaping and want to cut down, drop one level at a time and stay there for at least four weeks before going lower.

How Nicotine Strength Is Measured

Nicotine strength is shown in milligrams per millilitre (mg/ml). A bottle labelled 20mg contains 20mg of nicotine in every 1ml of liquid. Some brands use percentages instead: 20mg = 2%, 10mg = 1%, 5mg = 0.5%, 3mg = 0.3%.

The UK legal maximum is 20mg/ml (2%) under TPD rules. You will not find anything stronger on a legitimate UK vape shop shelf.

A cigarette contains roughly 10mg to 12mg of nicotine in the tobacco, but your body only absorbs about 1mg to 1.5mg per smoke. Vaping delivers nicotine differently, so there is no exact one-to-one conversion. The chart below gives you a practical starting point.

Nicotine Strength Chart: Match Your Smoking Habit

If you are unsure between two strengths, go higher. You can always reduce later. Starting too low means cravings never get satisfied, and that is when people go back to cigarettes.

Nic Salts vs Freebase: Which Type Suits Which Strength?

These are the two types of nicotine used in e-liquids. They feel different at the same mg level, and picking the wrong type is almost as common as picking the wrong strength.

The practical takeaway: if you are switching from cigarettes, nicotine salts at 20mg in a pod kit give the closest match to smoking. If you already vape and prefer bigger clouds at lower strengths, freebase at 3mg to 6mg in a sub-ohm setup is the way to go. Avoid 18mg or 20mg freebase unless you specifically enjoy a harsh throat hit.

Popular nic salt ranges include ELFLIQ, Fumot nic salt, Lost mary nic salt, Ghost Salts, Pod Salt Nexus, and SKE Crystal Salts. For a wider look at what brands are worth your money, our best vape brands in the UK guide covers the full picture.

What Nicotine Level Do Prefilled Pods Use?

Since the UK banned single-use disposable vapes in June 2025, prefilled pod kits have become the go-to replacement. Almost every prefilled pod contains 20mg nicotine salt. Brands like Hayati, Elf Bar, Lost Mary, and Crystal Prime all use the TPD maximum.

This matters if you want a lower strength. Most prefilled pods do not come in 10mg or 5mg. To go lower, you need a refillable vape pod kit paired with bottled nic salts at the strength you want. Our top 10K puffs prefilled pod kits roundup compares the best current options if you are staying at 20mg.

How to Step Down Your Nicotine Over Time

Gradually reducing your nicotine is one of the biggest advantages vaping has over cigarettes. The NHS recommends stepping down rather than quitting nicotine cold turkey.

• Weeks 1 to 6: Stay at the strength that stops cigarette cravings. For most smokers, 20mg nic salt.

• Weeks 6 to 12: Drop to 10mg. You might vape more often to compensate, and that is normal.

• Weeks 12 to 20: Drop to 5mg. Cravings are much weaker by this point.

• Week 20 onward: Try 0mg if your goal is to quit nicotine entirely. Plenty of vapers stay at 5mg long term, and that is fine.

How the October 2026 Vape Duty Changes the Maths

From 1 October 2026, a Vaping Products Duty of £2.20 per 10ml applies to all e-liquids sold in the UK. Bottled nic salts and e-liquids will cost roughly £2 to £3 more per bottle.

Higher strength liquids give you more nicotine per millilitre, so you use less liquid overall. Vaping 20mg instead of 10mg could save a few pounds a week once the duty kicks in. That is not a reason to vape a strength that feels too strong, but if two levels both feel comfortable, the higher one stretches further.

Signs You Have Picked the Wrong Strength

Too high

• Dizzy or lightheaded after a few puffs

• Nausea, especially in the morning

• Headaches that ease when you stop vaping

• Harsh, burning throat sensation

Too low

• Still craving cigarettes through the day

• Vaping constantly without feeling satisfied

• Burning through pods or liquid faster than expected

• Restless or irritable between sessions

If you are buying vapes online in the UK for the first time, buy a single 10ml bottle or one prefilled pod to test the strength before committing to a larger order.

Conclusion

Getting the nicotine strength right matters more than which brand you pick or what flavour you choose. The wrong strength will make you either sick or unsatisfied, and neither leads anywhere good.

Start by matching your smoking habit to the chart above. Heavy smokers do best at 20mg nic salt in a pod kit. Light or social smokers can start lower at 5mg to 10mg. If you are coming from a disposable vape, you were already on 20mg, so a prefilled pod kit at the same strength is the smoothest transition. Once settled, step down at your own pace. The priority is staying off cigarettes, not hitting zero as fast as possible. We offer free delivery on orders over £25.

FAQ

Is 20mg nicotine too strong for a beginner?

Not if you are switching from 10+ cigarettes a day. 20mg nic salt in a pod kit delivers nicotine smoothly and closely matches smoking satisfaction. If you smoke fewer than five a day, 10mg or lower is better.

What nicotine strength is equal to a cigarette?

No exact conversion exists. A cigarette delivers about 1mg to 1.5mg of absorbed nicotine. A few puffs of 20mg nic salt in a pod kit delivers a similar amount, but the speed and feel differ.

Can I mix different nicotine strengths?

Yes, in a refillable kit. Mixing a 20mg and a 0mg bottle in equal parts gives you roughly 10mg. This is a common way to create a strength that is not sold off the shelf.

What nicotine level do Elf Bar and Lost Mary pods use?

Almost all prefilled pods from Elf Bar, Lost Mary, Hayati, and Crystal Prime use 20mg nicotine salt. If you want a lower strength in the same flavours, ELFLIQ nic salts come in 10mg and 20mg bottles for refillable kits. Our best ElfBar flavours guide covers the top picks.

Is 0mg vaping pointless?

No. 0mg e-liquid lets you keep the hand-to-mouth habit and flavour without nicotine. It is a useful final step if you have already reduced to 5mg and want to quit nicotine entirely. Many online vape stores in the UK stock 0mg options in both freebase and shortfill formats.
