What Are Nic Salts? The Simple Explanation
What are nic salts in basic terms? Nicotine salts are the natural form of nicotine as it exists in the tobacco leaf. In its natural state, tobacco nicotine bonds chemically with other organic compounds, forming what chemists call a salt structure. This is where the name comes from.
Standard freebase nicotine, which older e-liquids use, is a refined form of nicotine with a high pH level. That high pH is what produces the harsh throat hit many vapers experience at higher strengths. Freebase works fine at lower strengths like 3mg or 6mg, but at 18mg or 20mg it becomes noticeably uncomfortable for most people.
Nic salts solve this problem. Manufacturers add benzoic acid to the nicotine during production, which lowers the pH significantly. The result is a liquid that delivers high nicotine strengths, up to the UK legal maximum of 20mg, without the harshness. This is why what are nic salts e liquid options feel so much smoother to vape than equivalent freebase juices at the same strength.
The why nic salts are smoother and stronger guide at Vaping 101 covers the full chemistry behind this for anyone who wants the deeper explanation. The freebase vs nic salts guide covers the comparison side-by-side in practical terms.
What Ingredients Are in Nic Salts?
Understanding what ingredients are in nic salts helps you know exactly what you're vaping. The ingredient list for a standard nic salt e-liquid looks like this:
Every nic salt e-liquid contains these core components:
- Vegetable Glycerine (VG): the base liquid responsible for vapour production and a slightly sweet character. In nic salts, this is typically 50% of the blend.
- Propylene Glycol (PG): the thinner base liquid that carries the flavour compounds and produces the throat hit sensation. Also typically 50% of the blend in nic salts.
- Food-grade flavouring concentrates: these are pharmaceutical-grade flavour compounds tested for vapour compatibility, the same class used in the food industry.
- Nicotine in salt form: the natural nicotine extracted from tobacco leaf, combined with benzoic acid to lower the pH and create the smooth, fast-absorbing salt formulation.
The 50/50 VG/PG ratio is the standard for what are nic salts vape liquids because it creates a thin enough consistency to wick properly in the low-resistance coils found in pod vapes and starter kits.
All nic salts sold in the UK must be TPD-compliant, meaning they come in 10ml bottles with a maximum nicotine strength of 20mg. Every product in the nic salts collection at Vaping 101 meets these standards. For a detailed breakdown of what VG and PG do in e-liquid, the VG and PG ratios guide covers both ingredients clearly.
How Nic Salts Differ From Freebase Nicotine
Nic salt guideThe practical differences between what are nic salts e liquid options and freebase e-liquids come down to four key areas.
Throat Hit
Freebase nicotine at high strengths produces a sharp, peppery throat hit that many vapers find uncomfortable. Nic salts at the same strength, even 20mg, feel smooth and gentle on the throat. This is the single biggest reason nic salts have become the preferred choice for ex-smokers who need higher nicotine but don't want harsh vapour.
Nicotine Absorption Speed
Nic salts enter the bloodstream significantly faster than freebase nicotine. Research suggests nic salts absorb in around six seconds, closely matching how quickly cigarettes deliver nicotine. This speed is important for cravings: a fast, satisfying hit makes it easier to resist reaching for a cigarette. Freebase nicotine absorbs more gradually over ten to fifteen seconds.
Quick differences:
- Nic salts: Smoother throat hit
- Nic salts: Faster absorption
- Nic salts: Best for pod vapes
- Freebase: Better for shortfills and sub-ohm
Device Compatibility
Nic salts work in low-powered devices only. The 50/50 VG/PG ratio and high nicotine concentration are designed for pod vapes, starter kits, and MTL tanks that operate at 8 to 15 watts with coils above 0.8 ohms. Using nic salts in a high-powered sub-ohm device pushes too much nicotine into the vapour, producing an uncomfortable experience.
Freebase nicotine in high-VG shortfill format suits sub-ohm devices. If you want a larger-format e-liquid rather than a 10ml bottle, browse the shortfills collection for nicotine-free options to which you add your own nic shots.
Strength Options
What are nic salts available in, strength-wise? The main options in the UK are 5mg, 10mg, 15mg, and 20mg. Freebase nicotine typically tops out at 18mg in practise because the throat hit becomes too harsh above that. Nic salts can go to 20mg comfortably due to their smooth delivery.
The nic salts vs 50/50 guide covers all these differences in more detail. For a full breakdown of nic salt ingredients and chemistry, check the nic salts vs nic shots comparison which explains how both salt and freebase nicotine behave in vape juice.
What Are the Best Vape Kits for Nic Salts?
Knowing what are the best vape kits for nic salts comes down to one rule: low wattage, high resistance coils. Nic salts need a device that operates between 8 and 20 watts with coils rated at 0.8 ohms or above. These conditions produce the right amount of vapour and nicotine delivery without overwhelming the vaper.
Pod Systems
Pod vapes are the most popular choice for nic salts. They're compact, draw-activated or button-fired, and designed specifically for the 50/50 VG/PG ratio of nic salt liquids. OXVA and Vaporesso both produce highly rated pod systems well-matched to nic salt use.
Brands like OXVA offer pod options that optimise flavour delivery from nic salt liquids, while Vaporesso produces pod kits with coil technology designed to extract maximum flavour from 50/50 e-liquids.
Starter Kits
Starter kits often include a small tank and a battery with adjustable wattage. These work well with nic salts when set to the lower end of the wattage range. A starter kit gives you more control over your vaping experience and suits vapers who want to try both nic salts and 50/50 freebase e-liquids without committing to a single format device.
Avoid using nic salts in advanced vape kits and sub-ohm setups. These devices operate at 40 watts or more, which vaporises too much liquid per puff and delivers an uncomfortable amount of nicotine in a very short time.

Choosing the Right Nic Salt
Start with your device first. If you use a pod vape or starter kit, choose a 50/50 nic salt in a strength that matches your nicotine needs. If you use a sub-ohm kit or high-powered advanced vape kit, avoid nic salts and choose a shortfill with a nic shot instead.
For flavour, disposable-inspired ranges like Bar Juice 5000 and Elfliq are the easiest first step for vapers moving from disposable vapes. Dinner Lady is better for dessert profiles, while Vampire Vape suits vapers who want classic UK flavours with fruit, menthol, and stronger identity.
