What Are Nic Salts? How They Work And How To Use Them In 2026
Nicotine salts, commonly known as nic salts, are a form of vape juice that uses a chemically modified version of nicotine to deliver a smoother throat hit and faster absorption than traditional freebase nicotine. Since the UK disposable vape ban in June 2025, nic salts have become the most popular type of vape liquid in the country. If you have ever used a disposable vape, the e-liquid inside was almost certainly a nic salt.
This guide explains how nic salts work at a chemical level, why they feel different from standard vape juice, how to use them properly, and answers the most common questions and misconceptions around them.

How nic salts work: the science
All e-liquid contains nicotine in one of two chemical forms: freebase nicotine or nicotine salt. The difference between the two comes down to pH and how that affects the way nicotine interacts with your body.
Freebase nicotine is created by stripping the nicotine molecule of its natural proton, raising its pH to around 7 to 8. This makes it more volatile and easier to vaporise, but it also makes the vapour harsher on the throat at higher concentrations. Freebase nicotine has been the standard form used in cigarettes since the 1960s and was carried over into early vape juice formulations.
Nicotine salt is the form of nicotine that occurs naturally in the tobacco leaf. E-liquid manufacturers recreate this by combining freebase nicotine with an organic acid, most commonly benzoic acid. This lowers the pH of the nicotine to around 5 to 6, which does two important things. First, it makes the nicotine much smoother to inhale, even at high concentrations like 20mg. Second, it allows the nicotine to cross into the bloodstream more quickly, reaching the brain in as little as 6 to 10 seconds after inhalation. This speed of delivery is what makes nic salts feel closer to the sensation of smoking a cigarette than any other type of vape juice.
The addition of benzoic acid also lowers the vaporisation temperature of the nicotine, which means nic salts can be vaped effectively at lower wattages. This is why nic salts pair naturally with small, low-power pod kits rather than high-power sub-ohm devices.
Nic salts vs freebase nicotine: how they actually differ
The practical differences between nic salts and freebase nicotine come down to how each one feels when you vape it and which devices they work best with. Understanding these differences helps you choose the right type for your needs.
| Feature | Nic salts | Freebase nicotine |
|---|---|---|
| Chemical process | Nicotine bonded with benzoic acid, lowering pH to 5-6 | Nicotine stripped of its proton, raising pH to 7-8 |
| Throat hit | Smooth, even at 20mg | Gets harsher as strength increases, uncomfortable above 12mg for most vapers |
| Absorption speed | Fast. Reaches the brain in approximately 6 to 10 seconds | Slower. Takes longer to satisfy cravings |
| Best device | Low-power MTL pod kits (8-15W) | Higher-power devices, sub-ohm kits (30W+) |
| Bottle format | 10ml bottles, typically 50/50 PG/VG | 10ml bottles (3-18mg) or shortfills (0mg, 50-100ml) with nic shots |
| Vapour production | Small, discreet clouds | Can produce large, dense clouds in sub-ohm setups |
| Best for | Ex-smokers, beginners, anyone who previously used disposable vapes | Experienced vapers, cloud chasers, vapers on low nicotine strengths |

A brief history of nic salts
Nicotine salts were not always part of vaping. For the first decade of the e-cigarette industry, freebase nicotine was the only option available. This worked reasonably well at lower concentrations, but ex-smokers who needed higher nicotine levels to manage cravings often found the throat hit too harsh to tolerate.
The breakthrough came in 2015 when the US company Pax Labs (later known as JUUL Labs) filed a patent for a nicotine salt formulation using benzoic acid. Their research showed that combining nicotine with an organic acid dramatically improved absorption speed while reducing harshness. When JUUL launched its pod system using this technology, it became one of the fastest-growing consumer products in history. The concept was quickly adopted by e-liquid manufacturers worldwide, and by 2020 nic salts had become a mainstream product in the UK market.
Today, nic salts are the dominant vape juice format in the UK, driven further by the June 2025 disposable vape ban. With disposables gone, the 10ml nic salt bottle paired with a refillable pod kit has become the standard setup for millions of UK vapers.
How to use nic salts
Using nic salts is straightforward, but there are a few practical points that are specific to this type of vape juice. Getting these right will improve your experience and help your coils last longer.
Choose the right device
Nic salts are designed for low-power, mouth-to-lung (MTL) pod kits. These devices produce small amounts of vapour per puff, which is what you want when vaping higher nicotine concentrations. Devices like the OXVA Xlim Go 2 and the Elf Bar ELFX Mini are both popular choices for nic salt vaping.
Do not use nic salts in a high-power sub-ohm device. Sub-ohm kits produce much larger volumes of vapour, which means each puff delivers far more nicotine. Using 20mg nic salt in a sub-ohm kit would result in dizziness, nausea, and an extremely unpleasant experience. Sub-ohm devices are designed for low-strength freebase vape juice (3mg to 6mg), not nic salts.
Fill and prime your pod
Fill your pod with nic salt vape juice and wait 5 to 10 minutes before your first draw. This allows the cotton wick inside the coil to fully absorb the liquid. Skipping this step can burn the coil and produce a harsh, charred taste on your very first puff. For a full guide to coil priming and care, see our vape coils guide.
Adjust your expectations
If you are used to freebase nicotine, nic salts will feel noticeably different. The throat hit is milder, the nicotine satisfaction arrives faster, and you will likely need fewer puffs to feel satisfied. Many vapers switching from freebase find they vape less frequently with nic salts because each session is more efficient at delivering nicotine.
Common misconceptions about nic salts
Are nic salts more addictive than freebase?
Not inherently. Nic salts and freebase vape liquid at the same mg strength contain the same amount of nicotine per ml. The difference is in how quickly that nicotine reaches your brain. Nic salts absorb faster, which means each puff feels more satisfying more quickly. This can lead to consuming less vape juice overall, but it does not change the fundamental addictiveness of nicotine itself. Both types are equally addictive at the same total nicotine intake.
Are nic salts stronger than normal vape juice?
Not by default. Nic salts are available in 5mg, 10mg, and 20mg in the UK. Freebase vape juice is available in 3mg, 6mg, 12mg, and 18mg. The mg number on the bottle determines how much nicotine is in the liquid, regardless of whether it is a nic salt or freebase. A 10mg nic salt contains the same amount of nicotine per ml as a 10mg freebase. The difference is that the nic salt will feel smoother and absorb faster at that same concentration.
Do nic salts damage coils faster?
No. Coil wear depends on the sweetener content and VG/PG ratio of the vape juice, not on whether it uses nic salt or freebase nicotine. Nic salts are typically 50/50 PG/VG, which is actually gentler on coils than the high-VG (70/30+) vape juice used in sub-ohm kits. If your coil is wearing out quickly, the cause is more likely sweetener build-up from the flavouring or chain vaping without allowing the wick to re-saturate.
Can I mix nic salts with freebase vape liquid?
While it is technically possible, it is not recommended. Mixing two different nicotine formulations makes it difficult to predict the throat hit, absorption speed, and effective nicotine strength of the resulting liquid. Stick to one type per refill for a consistent experience.
Are nic salts safe?
Nic salts are subject to the same UK TPD regulations as all other vape juice. Every nic salt sold legally in the UK has been tested, registered with the MHRA, and must comply with strict ingredient, labelling, and packaging standards. The maximum legal nicotine concentration is 20mg/ml, and bottles are limited to 10ml with child-resistant caps.
The benzoic acid used in nic salts is a food-grade compound that is found naturally in many fruits and is widely used as a preservative in the food industry. There is no current evidence to suggest that benzoic acid in vape liquid poses additional health risks beyond those associated with vaping in general.
As with all nicotine products, nic salts are addictive and are not suitable for non-smokers. If you are concerned about the health implications of vaping, the NHS maintains that vaping is substantially less harmful than smoking and remains a recommended tool for quitting cigarettes.

Frequently asked questions
What are nic salts?
Nic salts are a type of e-liquid that uses nicotine bonded with benzoic acid to create a smoother, faster-absorbing form of nicotine. They are designed for use in low-power MTL pod kits and are the most popular e-liquid format in the UK since the disposable vape ban.
How do you use nic salts?
Fill a refillable pod with nic salt vape liquid, wait 5 to 10 minutes for the coil to prime, and take gentle draws from the mouthpiece. Use a low-power MTL pod kit, not a sub-ohm device. For device recommendations, see our beginner's guide to vape kits.
What is the difference between nic salts and normal vape juice?
Normal vape juice (freebase nicotine) uses a higher-pH form of nicotine that can feel harsh at high strengths. Nic salts use a lower-pH formulation that is smoother to inhale and absorbs into the bloodstream faster. Both contain nicotine, but nic salts are better suited to higher strengths and low-power devices.
Are nic salts bad for you?
Nic salts are regulated to the same standards as all UK e-liquids. They are not risk-free, but the NHS states that vaping is substantially less harmful than smoking. The benzoic acid used in nic salts is a food-grade compound with no current evidence of additional harm when vaped.
Can I use nic salts in any vape?
No. Nic salts should only be used in low-power MTL devices and pod kits. Using nic salts in a high-power sub-ohm device will deliver far too much nicotine per puff and can cause dizziness, nausea, and headaches.
What nicotine strength nic salt should I use?
This depends on your smoking history and how often you vape. For detailed guidance, see our nicotine strength guide which matches your daily cigarette intake to the right nic salt strength.
Do nic salts expire?
Nic salts have a shelf life of approximately 1 to 2 years from the date of manufacture. Nicotine is more stable in its salt form than in freebase form, which means nic salts can last slightly longer before the flavour and potency begin to degrade. Store them in a cool, dark place away from direct sunlight.
Why are nic salts so popular since the disposable ban?
Disposable vapes used nic salt e-liquid, so vapers switching to refillable pod kits naturally gravitated toward bottled nic salts to replicate the same experience. The combination of smooth throat hit, fast nicotine delivery, and familiar flavour profiles made nic salts the obvious replacement for the e-liquid that was already inside disposables.
