Two types of nicotine. Two completely different experiences. One is smooth and fast. The other is bold and powerful.

If you have ever stood in a vape shop or browsed online wondering what the difference actually is between nic salt and freebase — you are not alone. It is one of the most searched questions in UK vaping, and understanding it properly makes a real difference to how much you enjoy every single puff.

This guide breaks it all down in plain language. No unnecessary jargon, no fluff — just everything you need to know to pick the right e-liquid for your device and your style.

And once you know which is for you, we will introduce you to the best of both right here at vapeonlinestore.co.uk.

Let’s go.

What Makes Nicotine in E-Liquid So Important?

Every e-liquid is built from four main ingredients — vegetable glycerin (VG), propylene glycol (PG), flavouring, and nicotine. The VG/PG ratio controls your cloud and throat hit. The flavouring gives you the taste you love. But it is the type of nicotine that fundamentally shapes how your vape feels and how quickly it satisfies you.

Get the nicotine type wrong and even the best flavour in the world will not feel quite right. Get it right and everything clicks into place.

There are two nicotine types used in UK vape juice today: freebase and nic salt. Both contain nicotine. Both work brilliantly — but in different ways, for different devices, and for different vaping styles.

What Is Freebase Nicotine?

Freebase nicotine is the original form of nicotine used in e-liquids since vaping first began.

The term “freebase” describes how the nicotine has been chemically processed. Essentially, protons are removed from naturally occurring nicotine to increase its alkalinity — pushing the pH level up to around 8 or 9. This makes the nicotine more potent when it vaporises and carries it effectively through your cells into the bloodstream.

Freebase has been the standard in e-liquids for over a decade. It is found in 10ml bottles at lower strengths and in 100ml shortfill bottles at 0mg — where you add your own nic shot to create the strength you want.

What freebase nicotine feels like:

Freebase delivers a pronounced, satisfying throat hit — that distinctive scratch at the back of the throat that many vapers enjoy and associate with a cigarette. At lower strengths like 3mg and 6mg this is pleasantly noticeable. As the strength increases, so does the intensity of the hit.

Where freebase nicotine works best:

Because of its higher pH, freebase works most effectively in higher-wattage, sub-ohm devices designed for DTL (direct-to-lung) vaping. These are the more powerful setups that produce larger clouds and use low-resistance coils. The extra heat required to vaporise freebase efficiently is exactly what these devices provide.

Freebase strengths available in the UK:

• 3mg — very light, ideal for experienced vapers stepping down

• 6mg — the most popular freebase strength in the UK

• 12mg — stronger hit, suits heavier former smokers

• 0mg shortfill — no nicotine, you add your own nic shot

What Is Nic Salt?

Nic salt — short for nicotine salt — is a newer and incredibly popular form of nicotine that transformed UK vaping when it was introduced. Today, it is the most widely used nicotine type among UK pod kit users.

Nicotine salt actually occurs naturally in tobacco leaves. For vaping, it is created by combining nicotine with an organic acid — typically benzoic acid. This process lowers the pH of the nicotine from the alkaline 8–9 of freebase down to around 5–6. That lower pH is the key to everything that makes nic salt special.

Nic salts are found in 10ml bottles and are available in 10mg or 20mg strengths in the UK, in line with TPD regulations.

What nic salt feels like:

The lower pH creates a dramatically smoother throat hit. Even at 20mg — which would feel extremely harsh as a freebase — nic salt feels gentle, clean, and effortless to inhale. There is no burning, no scratch, no harshness. Just smooth, satisfying nicotine delivery.

Thanks to its chemical structure, nic salt also absorbs into your bloodstream faster than freebase — typically delivering a noticeable nicotine hit within as little as six seconds. This rapid satisfaction is what makes nic salts so effective for vapers who want quick cravings relief.

Where nic salt works best:

Nic salt is built for low-wattage MTL (mouth-to-lung) pod kits and starter devices. Devices running at 10 to 15 watts with coil resistances of 0.6ohm and above are the ideal pairing. The 50/50 VG/PG ratio of most nic salt e-liquids wicks perfectly through tighter MTL coils, delivering consistent flavour with every draw.

Important: Never use 20mg nic salt in a sub-ohm tank or high-wattage setup. The combination of high nicotine and large vapour production would deliver too much nicotine per puff and leave you feeling uncomfortable very quickly. Keep high-strength nic salts for MTL pod kits only.

Nic Salt vs Freebase — The Key Differences at a Glance

Throat Hit — What Actually Feels Right for You?

The throat hit question is where most vapers make their decision.

Freebase nicotine kicks hard at the back of the throat, and at 12mg and above that kick gets seriously strong. If you liked the scratch of a cigarette, freebase at a moderate strength gives you something close. 

Nic salt sits at the opposite end of that spectrum. Even at full 20mg strength, the smoothness of the salt formula means you get the nicotine satisfaction without any of the harshness. Thanks to their lower alkalinity, nicotine salts offer a smoother inhale without the harsh throat hit, even at high nicotine strengths — making them more appealing to those who prefer a gentler vaping experience. 

Neither is better than the other. They are simply different. The right one depends entirely on what you enjoy.

Device Compatibility — This Is the Most Important Factor

This is where most people go wrong when picking e-liquid. The type of nicotine matters less than whether it matches your hardware. If you’re using a pod kit, nic salts are the better pick nine times out of ten. If you’re running a sub-ohm setup, freebase is the only sensible option at those wattages. 

Here is the simple breakdown:

Use nic salt if you have:

• A pod kit (prefilled or refillable)

• A MTL vape pen or starter kit

• A device running at 10–15 watts

• A coil resistance of 0.6ohm or above

Use freebase if you have:

• A sub-ohm tank or box mod

• A DTL device running at 20+ watts

• A device with coils below 0.5ohm

• A kit designed for large clouds

Nicotine salts are better suited for low-wattage, mouth-to-lung (MTL) devices, such as pod systems. These compact and discreet devices offer a satisfying vaping experience without the need for massive vapour production. 

Can You Use Both? Absolutely.

There is no rule that says you have to pick one and stick with it forever.

Some vapers use nic salts during the day for quick satisfaction and swap to a lower strength freebase in the evening for longer sessions. There’s no rule that says you pick one and stick with it. 

Many UK vapers keep a small pod kit loaded with nic salt for on-the-go vaping, and a more powerful sub-ohm setup with freebase shortfill for home sessions. Both have their place in a well-rounded vaping routine.
