What Are Nic Salts? A Beginners Guide

Why Were Nic Salts Created?

For people switching from smoking, choosing the right nicotine strength can make a big difference. It needs to provide enough nicotine to manage cravings without making the inhale feel unnecessarily harsh.

Freebase nicotine tends to produce a stronger throat hit as the concentration increases. Nic salt formulations reduce that harshness, making higher nicotine strengths easier to inhale. That combination of higher-strength nicotine and a smoother draw is one of the main reasons nic salts became so popular with smokers moving over to vaping.

Nic Salts vs Freebase Nicotine

Freebase nicotine is the traditional form of nicotine used in e-liquids. It has a higher pH level, which creates a stronger throat hit as nicotine strength increases. At higher strengths, this can also mute flavour, leading to a peppery or sharp taste.

Nic salts are made by combining nicotine with an organic acid, which lowers the pH and generally makes higher-strength liquids feel smoother to inhale. Nic salt formulations are also commonly used in products designed to deliver nicotine quickly.

If you’re looking for a full, side-by-side breakdown of how these two nicotine types compare, our Nic Salts vs Freebase Nicotine guide goes into more detail.

Why Do People Choose Nic Salts?

Nic salts are popular because they combine higher nicotine strengths with a smoother inhale than comparable freebase liquids. They are particularly useful in smaller, lower-powered devices where each puff produces less vapour.

Many people switching from cigarettes also prefer them because nic salt formulations can deliver nicotine quickly without needing a large amount of vapour. Add in the huge choice of flavours now available and they are an easy fit for everyday MTL vaping.

Who Are Nic Salts Best For?

Nic salts are particularly well suited to smokers and recent switchers who prefer higher nicotine strengths without a strong throat hit. They are also a good fit for vapers who use lower-powered pod kits and prefer a tighter, mouth-to-lung draw with less vapour.

Because nic salts are available in different strengths, they also give you the flexibility to choose a nicotine level that better matches your current needs and adjust it over time if you want to.

How Quickly Do Nic Salts Work?

Nic salts are designed to deliver nicotine efficiently in lower-powered devices, and studies have found that some nicotine-salt formulations can produce higher nicotine levels than comparable freebase liquids.

How quickly you feel the effect will still depend on the nicotine strength, device, coil and the way you vape. In practice, this is one reason nic salts are popular with people who want a quicker sense of nicotine satisfaction from a smaller amount of vapour.

Do Nic Salts Affect Flavour?

Nic salts tend to have less of the peppery throat sensation associated with higher-strength freebase nicotine, which can make the flavour of the e-liquid feel cleaner and smoother.

That does not mean nicotine salts are completely flavour-neutral. The final taste will still depend on the nicotine strength, flavourings, PG/VG ratio and the device you use.

Are Nic Salts Harsh?

Nic salts are generally smoother to inhale than comparable-strength freebase e-liquids. Their lower pH reduces the sharper throat hit associated with stronger freebase nicotine, although higher nicotine strengths can still feel noticeable depending on the person and device.

This smoother inhale is one of the main reasons nic salts are so commonly used in lower-powered MTL setups.

Do Nic Salts Contain More Nicotine?

Nic salts do not automatically contain more nicotine than freebase e-liquids, but they are commonly sold in higher strengths because the smoother formulation makes those strengths easier to inhale.

In the UK, popular options include 5mg, 10mg and 20mg, although the exact strengths available vary by brand.

Which Devices Work Best with Nic Salts?

Nic salts are best suited to lower-powered devices that produce a smaller amount of vapour per puff, particularly refillable pod kits and compact vape pens.

Most are used for MTL vaping, although some modern pod kits also support a slightly airier RDL draw. Nicotine salt e-liquid is also used in prefilled vape pods, where the liquid is already built into the pod and ready to use.

The best setup will depend on the nicotine strength and the coil or pod recommended by the manufacturer.

Can You Sub-Ohm Vape Nic Salts?

You can use nic salts with some lower-powered sub-ohm pods, but they are generally better suited to compact MTL and RDL devices than high-powered sub-ohm kits.

What matters most is the nicotine strength, device power and the type of coil you are using. Stronger nic salts are usually paired with lower-powered setups that produce less vapour, while higher-powered sub-ohm kits are normally used with lower-nicotine e-liquids.

For high-powered sub-ohm vaping, many vapers use larger shortfill bottles with lower nicotine strengths instead.

Nic salts are a popular choice for vapers who want a smoother inhale at higher nicotine strengths, particularly when using compact MTL and refillable pod kits.

The right nicotine strength and device will depend on how you vape, but if nic salts sound like the right fit, you can explore our full range of flavours and strengths below.
