Nicotine salt e-liquid vs freebase e-liquid: difference and effect

If you use a pod system or are looking for a suitable liquid, you'll quickly come across two terms: nicotine salt e-liquid (nic salt) and classic e-liquid with freebase nicotine. In this guide you'll learn how they differ, how they feel when vaping and which liquid suits which device.

What is freebase nicotine?

Freebase nicotine is the "free" form of nicotine that has been used in liquids since the early days of the e-cigarette. Chemically, this form has a higher, i.e. more alkaline, pH value.

Properties of freebase nicotine

• Noticeable throat hit: at higher strengths (e.g. 12 or 18 mg/ml), freebase nicotine produces a noticeable, sometimes harsh scratch in the throat.
• Slower absorption: the nicotine is absorbed comparatively more slowly.
• Typical for sub-ohm vaping: at low strengths (3 or 6 mg/ml) it scratches little and is therefore often used in powerful devices with large vapour production and direct-to-lung (DL) draws.

What is nicotine salt?

Nicotine salt is created when nicotine is combined with an organic acid (usually benzoic acid). This lowers the pH of the liquid and makes the vapour milder.

Properties of nicotine salt

• Smooth draw: even at higher strengths such as 20 mg/ml, nicotine salt scratches the throat much less.
• Faster absorption: thanks to the lower pH, the nicotine is absorbed more quickly. This also means the effect sets in sooner, and high strengths are correspondingly intense.
• Clearer flavour: because the nicotine is less harsh, the flavour (e.g. fruit or menthol) comes through better.

Nicotine salt and freebase compared

Which liquid suits you?

Nicotine salt is a better fit if …

• you use a compact pod system with a mouth-to-lung (MTL) draw,
• you prefer a smooth draw without a strong scratch,
• you want to vape discreetly with little vapour.

Freebase is a better fit if …

• you like a noticeable throat hit,
• you vape with sub-ohm atomisers and big clouds,
• you use very low nicotine strengths (e.g. 3 mg/ml).

Important: nicotine salt is not "lighter" just because it tastes milder. 20 mg/ml nicotine salt in particular delivers a lot of nicotine. Choose your strength deliberately and, if in doubt, start lower. Our page on vape nicotine strength helps you choose. If you don't smoke or vape, don't start.

What applies in Switzerland?

• Sale from 18: since 1 October 2024, e-cigarettes and liquids – with and without nicotine – may only be supplied to adults, including online.
• Tax: nicotine-containing liquids and refills are taxed at CHF 0.20 per ml, plus 8.1% VAT. Read more in our article on the vape tax in Switzerland.
• Pod systems are not disposable vapes: rechargeable devices such as the ELFA Pro or Aroma King SMART are pod systems. Disposable e-cigarettes are subject to their own rules (including a max. 2 ml tank and cantonal bans in Valais and Geneva).

Everyday tips

• Use the right pods: use the pods or coils intended by the manufacturer. Nicotine salt liquids are designed for low-power devices.
• Don't mix up strengths: if you switch between freebase and nicotine salt, compare the mg/ml figure and not just how the draw feels.
• Store safely: keep liquids closed and out of reach of children and pets. If you suspect poisoning, you can reach Tox Info Suisse on 145; in an emergency call 144.
• Dispose of properly: empty pods, bottles and batteries don't belong in household waste but at the appropriate collection points.

Frequently asked questions

What is the main difference between nicotine salt and freebase?

Nicotine salt has a lower pH. As a result, it scratches the throat less and the nicotine is absorbed faster. Freebase nicotine has a stronger throat hit and is usually vaped at low strengths with sub-ohm devices.

Can I use nicotine salt in any device?

Nicotine salt is intended for pod systems and low-power MTL atomisers. Powerful sub-ohm devices produce a lot of vapour, which at high nicotine strengths can lead to very high nicotine intake.

Is nicotine salt weaker because it tastes milder?

No. A smoother draw says nothing about the amount of nicotine. 20 mg/ml nicotine salt contains just as much nicotine as 20 mg/ml freebase nicotine.
