What is the difference between nic salts and freebase nicotine?
The main difference between nic salts and freebase nicotine is the throat hit and the device each one suits. Nic salts bond nicotine with an acid for a smooth draw at 20mg in pod kits, while freebase keeps nicotine in its purer, more alkaline form for a sharper throat hit in higher-power kits. Both carry the same tobacco-derived nicotine, so the choice comes down to feel, strength and hardware.
Nicotine type decides how smooth, strong and satisfying every draw feels, which matters most for adult smokers switching from cigarettes. The NHS describes vaping as less harmful than smoking, though not risk-free. Royal Vapery stocks both nicotine types across its e-liquids range in UK-compliant 10ml bottles.
The table below compares nic salts and freebase nicotine across the 8 attributes that decide which one fits your setup.
| Characteristic | Nicotine salts | Freebase nicotine |
|---|---|---|
| Throat hit | Smooth, even at 20mg | Sharp, harsher above 12mg |
| Common UK strengths | 10mg and 20mg | 3mg, 6mg and 12mg |
| Vaping style | Mouth-to-lung (MTL) | MTL and direct-to-lung (DTL) |
| Best device | Pod kits and starter kits | Sub-ohm kits and high-power mods |
| Flavour style | Bold, sweet, bar-inspired | Subtler, layered, all-day |
| Cloud production | Small and discreet | Large and dense |
| Shelf life | Around 2 years, more stable | Around 2 years, oxidises faster |
| Best suited to | Heavy smokers switching, ex-disposable users | Cloud chasers, lower-strength vapers |
Throat hit and device fit explain why nic salts dominate pod vaping and bar-style flavours, while freebase powers sub-ohm clouds and subtler all-day blends. The sections below define each nicotine type in turn.
What is freebase nicotine?
Freebase nicotine is nicotine in its pure, deprotonated form, used in the first generation of e-liquids and in cigarettes since the 1960s. Manufacturers raise the pH of natural nicotine, historically with ammonia, to increase potency and speed absorption. Higher pH means higher alkalinity, which gives freebase a strong throat hit that grows harsher above 12mg.
Freebase suits vapers who want a cigarette-like draw, and vapers who run lower strengths for bigger clouds. Royal Vapery stocks freebase nicotine e-liquids in 3mg, 6mg and 12mg for MTL and DTL setups.
What are nicotine salts (nic salts)?
Nicotine salts are the natural form of nicotine found in the tobacco leaf, bonded with an acid to make them smooth to vape. Benzoic acid is the most common addition, with citric acid used in some blends, both lowering the pH for a gentler throat hit. Lower acidity lets nic salts carry 20mg of nicotine without harshness, a strength raw tobacco nicotine cannot manage at vaping temperatures.
Most UK nic salts use a 50/50 VG/PG blend in 10ml bottles at 10mg and 20mg, a format built for low-power pod kits and for adult smokers moving off cigarettes.
What are bar salts?
Bar salts are nic salt e-liquids blended with concentrated flavourings that recreate the taste of disposable vapes. Since the single-use disposable ban took effect on 1 June 2025, bar salts have become the main way UK vapers keep those bold flavours in a refillable format.
The nicotine inside is identical to any nic salt: salt-based, 10mg or 20mg, and best in low-power MTL pod kits. Only the flavour intensity changes, usually with a higher flavour percentage and a cooler finish. Subtler original-style salts remain available, though fewer brands still blend them. Royal Vapery stocks bar salts alongside classic nic salt blends for former disposable users.
How do nic salts and freebase nicotine differ in throat hit?
Nic salts deliver a smooth throat hit even at 20mg, while freebase nicotine delivers a sharp one that intensifies with strength. The acid in nic salts lowers the pH, so high-strength salts stay comfortable on the inhale. Freebase keeps a higher pH, which many ex-smokers enjoy because it mimics the catch of a cigarette.
Above 12mg, freebase can feel harsh enough to push new vapers into cutting their strength too soon, which leaves cravings unsatisfied. Vapers who find high-strength e-liquid uncomfortable usually prefer the softer nic salt draw. Experienced DTL vapers keep freebase at 3mg or 6mg precisely because the throat catch stays mild at low strengths.
How do nic salts and freebase nicotine differ in nicotine absorption?
Nic salts are widely reported to reach the bloodstream faster than freebase, though nicotine researchers dispute the size of the difference. The lower pH of nic salts is said to speed absorption and settle cravings quickly.
Some experts argue the smoother draw simply lets vapers inhale more deeply, creating the impression of a faster hit rather than a true chemical advantage. No settled consensus exists on the exact figure, so treat any precise percentage claim with caution.
Whichever view holds, most vapers describe nic salts as more immediately satisfying at 20mg, while freebase releases nicotine more gradually across a longer session.
Which nicotine strengths suit nic salts and freebase nicotine?
Nic salts suit 10mg and 20mg strengths, while freebase nicotine suits 3mg, 6mg and 12mg. UK law caps every nicotine e-liquid at 20mg/ml, alongside a 2ml pod limit and a 10ml bottle limit, a framework GOV.UK sets out under the Tobacco and Related Products Regulations 2016. Match the strength to your smoking habit:
- 3mg to 6mg: light smokers of 1 to 5 cigarettes a day, usually in freebase.
- 6mg to 12mg: moderate smokers of 5 to 15 a day, in freebase or 10mg nic salt.
- 10mg to 20mg: heavy smokers of 15 or more a day, in nic salt for a smooth high-strength draw.
Heavy smokers who find 12mg freebase harsh often move to 20mg nic salt, which carries the same nicotine with a softer throat hit.
Which devices work with nic salts and freebase nicotine?
Nic salts work with low-power pod kits, and freebase nicotine works with high-power sub-ohm kits. The 50/50 blend and high strength of nic salts suit compact pod kits running MTL coils above 1.0ohm.
Freebase in a high-VG shortfill needs the low-resistance coils of sub-ohm kits, below 0.6ohm, to vaporise the thicker liquid properly.
Best devices for nic salts
- Refillable and prefilled pod kits
- MTL coils of 1.0ohm to 1.8ohm
- Output of 8W to 15W
- 50/50 VG/PG at 10mg or 20mg
Adults switching from smoking suit compact starter vape kits paired with 20mg nic salt.
Best devices for freebase nicotine
- Sub-ohm kits and box mods
- Mesh coils below 0.6ohm
- Output of 25W to 80W
- 70/30 VG/PG at 3mg or 6mg
Cloud chasers reach for low-strength freebase in a high-VG shortfill, mixed with a nicotine shot.
Which is right for you, nic salts or freebase nicotine?
It depends on the draw, strength and clouds you want from your vape. Choose nic salts for a smooth, high-strength pod vape, and choose freebase for a sharp throat hit or big DTL clouds. The table below matches 6 common preferences to the right nicotine type.
| What you want | Choose |
|---|---|
| A smooth draw at high nicotine | Nic salts at 10mg or 20mg |
| A cigarette-like throat hit | Freebase at a higher strength |
| Big clouds and DTL vaping | Freebase in a high-VG shortfill |
| A discreet pod for switching from smoking | Nic salts in a pod kit |
| To lower nicotine over time | Freebase at 3mg or 6mg |
| Bold, sweet disposable-style flavour | Bar salts at 10mg or 20mg |
Many vapers keep both, running a nic salt pod through the day and a freebase shortfill for relaxed cloud sessions at home.

Frequently asked questions about nic salts and freebase nicotine
No, neither nic salt nor freebase nicotine is safer than the other. Both contain the same tobacco-derived nicotine and carry the same nicotine-related risks. The only chemical difference is the acid added to nic salts, usually benzoic acid, which changes the throat feel rather than the toxicity. Start at a lower strength if you are new to vaping.
No, freebase nicotine is not stronger than nic salts at the same strength. A 20mg nic salt and a 20mg freebase e-liquid hold the same amount of nicotine. Nic salts can feel stronger because the smooth draw lets you inhale more deeply, while freebase feels harsher at the throat for the same figure.
Yes, you can use freebase nicotine in a pod system at lower strengths of 3mg or 6mg. Low-strength freebase suits refillable pods with coils between 0.8ohm and 1.2ohm. Higher freebase strengths feel harsh in a small pod, so most pod users choose nic salts or low-strength freebase for a comfortable draw.
No, you should not use 20mg nic salts in a sub-ohm kit. Sub-ohm coils below 0.6ohm vaporise far more liquid, so a high-strength nic salt delivers too much nicotine at once and feels overwhelming. Nic salts belong in low-power MTL pod kits, while sub-ohm kits pair with high-VG shortfill.
MTL coils between 1.0ohm and 1.8ohm work best with nic salt e-liquids. High-resistance coils run at 8W to 15W, which suits the 50/50 VG/PG blend of most nic salts and keeps the throat hit smooth. A 0.8ohm mesh MTL coil handles 10mg nic salt at 12W to 18W.
Nic salt and freebase e-liquids last around 1 to 2 years from the manufacture date when stored correctly. Keep bottles sealed in a cool, dark place away from sunlight. Nic salts stay chemically stable slightly longer, while freebase oxidises faster and can turn a darker colour with a peppery edge over time.
No, a true 0mg nic salt or 0mg freebase does not exist, because both terms describe nicotine. Without nicotine there is no salt and no freebase. You can buy 0mg e-liquid, usually a shortfill, and vape it nicotine-free or add a nicotine shot to reach your preferred strength.
Bar salts are nic salts made with bolder, sweeter flavourings that copy the taste of banned disposable vapes. The nicotine type is identical: both are salt-based, both come in 10mg and 20mg, and both suit low-power MTL pod kits. The difference is flavour style and intensity, not nicotine strength.
Yes, you can mix nic salt and freebase e-liquid, though it is rarely necessary. Mixing blends the smooth salt draw with the sharper freebase throat hit and can muddy the flavour. Most vapers keep the two separate, using nic salts for a smooth pod vape and freebase for cloud production.
Yes, nic salts often taste bolder and sweeter than freebase e-liquids, because modern bar-style salts use concentrated flavourings. Freebase nicotine carries subtler, more layered flavours that suit longer all-day vaping. Some vapers report freebase flavour reads cleaner, while nic salt flavour lands harder on the inhale.
Nic salts are best for most beginners switching from smoking, because the smooth draw satisfies cravings at 10mg or 20mg without a harsh throat hit. A refillable pod kit paired with 20mg nic salt closely matches the routine of smoking. Heavy smokers usually start at 20mg, lighter smokers at 10mg.
Yes, freebase nicotine produces bigger clouds than nic salts in the right setup. Low-strength freebase in a high-VG shortfill, vaped on a sub-ohm kit, generates large, dense vapour. Nic salts run in low-power pod kits with a 50/50 blend, so they make smaller, more discreet clouds by design.
Nic salts and 10ml freebase e-liquids sit at a similar price per bottle in the UK. Freebase works out cheaper per millilitre in large shortfills. From 1 October 2026, GOV.UK confirms a Vaping Products Duty of £2.20 per 10ml applies to both nicotine types, with VAT charged on top.
