Best Nic Salt E-Liquid Strength Guide UK
What is the best nic salt e-liquid strength?
The best nic salt e-liquid strength matches your smoking history, 20mg suits heavy smokers, 10mg suits moderate smokers, and 5mg suits light or stepping-down vapers. Every UK nic salt caps at 20mg/ml, and each strength performs best in a low-wattage MTL pod kit.
Royal Vapery stocks nic salt e-liquid in every UK strength across brands such as ELFLIQ, IVG, Hayati and Elux, so a switching smoker can match nicotine to an old cigarette habit without giving up a favourite flavour. Picking the right level settles cravings on a compact pod kit without pushing too much nicotine into a single puff.
The NHS describes vaping as less harmful than smoking, though not risk-free. This guide is written for adult smokers and vapers aged 18 and over.
What nic salt strengths can you buy in the UK?
UK vape shops sell nic salt e-liquid in three strengths: 5mg, 10mg and 20mg. The Tobacco and Related Products Regulations 2016 cap nicotine at 20mg/ml, per GOV.UK, so 20mg is the strongest nicotine salt e-liquid on any UK shelf, sold in 10ml bottles. Each strength serves a different stage of switching from cigarettes.
The light option
The lightest UK strength: made for light smokers of under 5 a day and for vapers stepping down from 10mg.
The middle ground
The balanced middle strength: matched to moderate smokers who want steady all-day satisfaction.
The UK maximum
The strongest UK strength: built for heavy smokers who need fast craving relief in the first weeks.
The concentration is the only variable between the three. The 50/50 VG/PG ratio and the flavour formula stay identical across a range, so the decision rests on how much nicotine your body expects.
What nic salt strength should I choose?
It depends on your smoking history, the best nic salt e-liquid strength matches your old cigarette intake rather than the highest number on the shelf.
A strength set too low leaves cravings unsettled, while a strength set too high feels harsh and brings on a head-rush. The table below pairs daily cigarette intake with a starting strength and a suitable device.
| Smoker type | Cigarettes per day | Nic salt strength | Device type |
|---|---|---|---|
| Heavy smoker | 20+ | 20mg (2%) | Pod kit or MTL starter kit |
| Moderate smoker | 10 to 20 | 10mg (1%) | Pod kit or MTL starter kit |
| Light smoker | 5 to 10 | 5mg to 10mg | Pod kit or MTL starter kit |
| Social smoker | Under 5 | 5mg (0.5%) | Pod kit or MTL starter kit |
If you sit between two rows, start with the higher strength. Fewer puffs of a stronger nic salt e-liquid satisfy more reliably than constant puffing on a weaker one, and stepping down later takes one bottle.
Who should choose 20mg nic salt?
Heavy smokers who got through 20 a day or more should choose 20mg nic salt e-liquid. This strength is the UK legal maximum at 20mg/ml, and it delivers nicotine within a few puffs to settle strong cravings during the first weeks of switching.
Keep 20mg in a tight MTL pod kit at 8W to 15W, because higher wattage pushes too much nicotine into each puff. Former disposable users ran 20mg as standard, so a 20mg refill in a prefilled pod kit holds a familiar strength after the single-use vape ban of 1 June 2025.
Who should choose 10mg nic salt?
Moderate smokers who got through 10 to 20 a day should choose 10mg nic salt e-liquid. This middle strength keeps cravings quiet while fruit, dessert and menthol flavours come through clearly, because the nicotine sits less prominently than at 20mg.
10mg suits any pod kit or MTL setup, and it handles a wider power window of 10W to 18W. Vapers who start at 20mg commonly drop to 10mg once the early cravings pass, then stay there long term.
Who should choose 5mg nic salt?
Light and social smokers of under 5 a day should choose 5mg nic salt e-liquid. This is the lightest UK strength at 0.5%, the throat hit nearly disappears, and flavour becomes the main event.
5mg suits vapers stepping down from 10mg who keep the hand-to-mouth habit on less nicotine. Fewer 5mg options reach UK shelves than 10mg or 20mg, though the range grows as more vapers lower their intake.
How does nic salt strength compare to freebase nicotine?
The main difference is throat hit: nic salt e-liquid feels smoother than freebase nicotine at the same mg/ml, because benzoic acid lowers the pH of the liquid. That smoothness lets a brand offer 20mg comfortably, where 18mg freebase feels sharp in the same kit. Nic salts absorb faster too, which settles a craving sooner.
| Characteristic | Nic salt e-liquid | Freebase e-liquid |
|---|---|---|
| Throat hit | Smooth, even at 20mg | Sharp, harsher as strength rises |
| Nicotine delivery | Faster absorption | Slower absorption |
| UK strengths | 5mg, 10mg, 20mg | 3mg, 6mg, 12mg, 18mg |
| VG/PG ratio | 50/50 | 50/50 or 70/30 |
| Device compatibility | Low-wattage MTL pod kit | Sub-ohm kit or wider MTL range |
| Best for | New switchers, all-day pod use | Cloud chasing, paced vaping |
Freebase nicotine keeps its place for cloud chasing at low strengths in bigger devices. For a smoker moving to a compact pod kit, the smoother and faster nic salt is the more comfortable match.
What device and coil suit each nic salt strength?
Every nic salt e-liquid strength suits a low-wattage, mouth-to-lung (MTL) device: a pod kit, a starter kit or an MTL vape pen. Nic salts are blended at a 50/50 VG/PG ratio for smaller, higher-resistance coils, and they perform best on low power. The table below pairs each strength with a wattage and coil range.
| Nic salt strength | Wattage range | Coil resistance | Draw style |
|---|---|---|---|
| 20mg | 8W to 15W | 0.8Ω to 1.2Ω | Tight MTL |
| 10mg | 10W to 18W | 0.8Ω to 1.0Ω | MTL |
| 5mg | 12W to 18W | 0.8Ω to 1.0Ω | MTL to loose MTL |
Start on a higher-resistance coil of 1.0Ω to 1.8Ω for a tighter draw and steadier nicotine delivery. A beginner-friendly starter vape kit sets the wattage from the coil you fit, which removes the guesswork.
Avoid sub-ohm kits: nic salts belong in MTL coils. A sub-ohm coil of 0.6Ω and below produces large clouds and pulls far too much nicotine into a single breath, which causes coughing and a rough head-rush. Freebase e-liquid at 3mg or 6mg is the correct choice for a sub-ohm device.
How do you convert nic salt strength from percentage to mg?
Multiply the percentage by 10 to convert nic salt strength to mg/ml: 0.5% equals 5mg, 1% equals 10mg, and 2% equals 20mg. UK labels print mg/ml, while US brands and overseas reviews print a percentage. The table lines up both measurement standards.
| Percentage | mg/ml | UK nic salt strength |
|---|---|---|
| 0.5% | 5mg/ml | 5mg |
| 1% | 10mg/ml | 10mg |
| 2% | 20mg/ml | 20mg (UK maximum) |
| 3.5% | 35mg/ml | Not legal in the UK |
| 5% | 50mg/ml | Not legal in the UK |
Anything labelled 3.5% or 5%, which equals 35mg/ml or 50mg/ml, sits above the 20mg/ml TRPR cap and cannot be sold legally for direct vaping in the UK. A 10ml bottle at 20mg/ml holds 200mg of nicotine in total, and 10ml is the largest bottle size permitted for nicotine-containing e-liquid.
What are the signs of the wrong nic salt strength?
Two clear signs point to the wrong nic salt strength: discomfort from too much nicotine, or constant cravings from too little. Reading these signals early lets you adjust before a poor experience sends you back to cigarettes.
Signs the strength runs too high
- ↓Lightheadedness: a head-rush or dizziness within a few puffs.
- ↓Nausea: a queasy or unsettled stomach.
- ↓Harsh draw: roughness even on a tight MTL coil.
- ↓Muted flavour: nicotine overpowering the blend.
Step down one strength, for example 20mg to 10mg.
Signs the strength runs too low
- ↑Constant puffing: vaping non-stop without feeling settled.
- ↑Morning cravings: reaching for a cigarette first thing.
- ↑Fast pod use: emptying pods quicker than expected.
- ↑Tobacco pull: cigarettes still on your mind at the end of a day.
Step up one strength, for example 5mg to 10mg.
Give any new strength 3 to 4 days before switching again, because your body needs time to adjust after a change. If discomfort continues, speak to a GP or NHS Stop Smoking Services for personal support.

Nic salt strength FAQs
Yes, 20mg nic salt is the strongest strength sold in the UK, capped at 20mg/ml under TRPR rules. It feels smoother than 18mg freebase nicotine in the same kit, because benzoic acid lowers the pH. For a smoker coming off 20 cigarettes a day, 20mg settles cravings fastest in the early weeks.
Choose 20mg nic salt if you have just stopped a pack-a-day habit and cravings feel strong. Choose 10mg nic salt once the worst cravings pass and you want a lighter throat hit. Most vapers start on 20mg, then step down to 10mg after a month or two of steady vaping.
Yes, 10mg nic salt is strong enough for most moderate smokers who got through 10 to 20 a day. This middle strength keeps cravings manageable and lets fruit, dessert and menthol flavours come through cleanly. If morning cravings still feel intense, 20mg nic salt is the more reliable starting point.
Yes, 5mg nic salt is worth it for light vapers who want maximum flavour with barely any throat hit. It suits people who smoked under 5 a day, plus vapers stepping down from 10mg. You can vape at 5mg across a full day without taking in too much nicotine.
20mg/ml means 20 milligrams of nicotine sit in every millilitre of e-liquid. A standard UK 10ml nic salt bottle at 20mg/ml holds 200mg of nicotine in total. 20mg/ml is the highest nicotine strength allowed for sale in the UK under TRPR regulations, per GOV.UK.
2% nicotine equals 20mg/ml, the maximum legal nic salt strength in the UK. Some overseas brands label bottles as 2% rather than 20mg, though the concentration of nicotine is identical. Multiply any percentage by 10 to reach the mg/ml value, so 1% equals 10mg and 0.5% equals 5mg.
Yes, you can mix nic salts to make 15mg by combining equal parts of a 10mg bottle and a 20mg bottle in the same flavour and brand. The blend averages to 15mg/ml. This gives a useful stepping stone when the jump between two strengths feels too large in one move.
Vape 20mg nic salt between 8W and 15W on a coil resistance of 0.8 ohm or higher. Going above 15W pushes too much nicotine into each puff and leaves you lightheaded. Most pod kits set the wattage from the coil you fit, so a tight MTL coil keeps 20mg comfortable.
No, you cannot comfortably use nic salts in a sub-ohm kit. Sub-ohm coils of 0.6 ohm and below produce large clouds and pull far too much nicotine into a single breath, which causes coughing and a rough head-rush. Nic salts belong in low-wattage MTL pod kits with high-resistance coils.
Bar salts are nic salts with bar-inspired flavours, so the nicotine formula is identical between them. Both use a 50/50 VG/PG base, arrive in 10mg and 20mg, and run best in low-wattage MTL pod kits. The only real difference is flavour style rather than strength. Browse the bar salt e-liquids range for bar-style blends.
Yes, lower nic salt strengths give more flavour, because less nicotine sits in the mix to mask the profile. At 5mg, fruit, dessert and menthol notes taste sharper, while 20mg dulls a delicate blend slightly. The flavour formula stays the same across strengths, so the effect is subtle rather than dramatic.
It varies with how often you vape. A 10ml nic salt bottle lasts a moderate pod-kit vaper roughly one week, and a lighter vaper longer than that. Unopened, nic salt e-liquid keeps for around 1 to 2 years, so check the batch code and expiry date printed on the bottle.
Royal Vapery publishes no cigarette-equivalence figure for 20mg nic salt. Nicotine absorption changes with the device, the draw length and the coil, so no fixed puff-for-puff number applies. For personal advice on switching from cigarettes, contact NHS Stop Smoking Services or your GP, who can tailor guidance to your own habit.
