Nic salt vs freebase comes down to your device and the strength you need. Nic salts use nicotine bonded with a mild acid, so 10mg to 20mg stays smooth in a small pod kit. Freebase is plain nicotine; it gets harsh at high strengths, so it suits lower strengths in bigger, cloudier tanks. If you use a pod kit and need a stronger hit, choose nic salt; if you run a big tank for clouds, choose freebase.
The short comparison
| Nic salt | Freebase | |
|---|---|---|
| What it is | Nicotine combined with a mild acid | Nicotine on its own |
| Typical UK strengths | 5mg, 10mg, 20mg | 3mg, 6mg, 12mg, 18mg |
| Throat hit at high strength | Smooth | Sharp |
| Best device | Mouth-to-lung pod kit, coils around 0.8 to 1.2 ohm | Pod kit at low strength, or a sub-ohm tank |
| Usual PG/VG | 50/50 | 50/50 up to 70VG or more |
| Bottle sizes | 10ml | 10ml with nicotine; large shortfills with none |
Throat hit: the real difference
If you have decided nic salts suit you, a good range of nic salt e-liquids is the place to start comparing flavours and strengths.
Throat hit is the catch you feel at the back of the throat when you inhale. Freebase nicotine gives a stronger one, and it grows quickly with strength. Plenty of ex-smokers like a little of it, which is why some still choose freebase at 6mg or 12mg. Nic salts soften it, so a 20mg salt can feel gentler than a 12mg freebase.
Strength and how much you vape
Freebase users on sub-ohm tanks inhale a lot of vapour, so they stay on low strengths like 3mg. Pod kit users take smaller, tighter draws, so they need more nicotine per puff, which is where 10mg and 20mg salts come in. If a disposable was your daily, the strength guide explains why 20mg is usually the right starting point.
Flavour
Both carry flavour well. Nic salts tend to be mixed 50/50 PG to VG, and PG carries flavour sharply, so fruit and ice blends come through clearly. Freebase shortfills often run high VG for clouds, which can mute flavour a little in exchange for density. The PG/VG ratio guide explains the trade-off.
Cost
Freebase shortfills come in large bottles with no nicotine, and you add a nicotine shot yourself. That is cheap per ml but means mixing. Nic salts come ready to vape in 10ml bottles, and you use less liquid per day in a pod kit. At the two UK stores we track, the ranges we cover cost from £2.39 to £2.59 a bottle at the cheaper store (prices checked 2 November 2026). Our cheapest nic salts guide has the full price table.
Can you mix nic salts and freebase?
You can, as long as the combined strength stays within your comfort zone and you know the maths. Most people do not need to. If you want a strength between two options, Bar Juice 5000 sells some flavours at 15mg, such as Blue Bubba, which avoids mixing altogether.
Shortfills and nic shots explained
Freebase often comes as a shortfill: a large bottle of nicotine-free liquid with space left at the top. You add a 10ml nicotine shot to reach a low strength, usually 3mg in a 60ml bottle. UK rules allow this because the nicotine is sold separately in 10ml containers. Nic salts skip that step. The nicotine is already in the 10ml bottle at the strength printed on the label.
Switching from freebase to nic salts
Coming from 12mg or 18mg freebase in a pod kit, most people find 10mg or 20mg nic salt feels similar but smoother. Coming from a sub-ohm tank at 3mg or 6mg, the change is bigger: you will be moving to a tighter draw and a much smaller device, so start at 10mg and adjust. Prime the new coil before your first puff, as our coil priming guide shows.
Signs you have picked the wrong one
- Coughing or a harsh catch on every puff: probably freebase at too high a strength, or a nic salt that is too strong for you.
- Puffing constantly and never feeling satisfied: strength too low, or freebase in a pod kit when you need a salt.
- Thin vapour and muted flavour from a big tank: you may have a nic salt in a device made for freebase.
Nic salt vs freebase in a pod kit
Most people asking this question own a pod kit, so here is the short version for that device. A pod kit with a coil around 1 ohm and a tight mouth-to-lung draw works with both. Freebase at 6mg or 12mg gives a more noticeable throat hit; nic salt at 10mg or 20mg gives more nicotine with less harshness. If you used disposables, salts will feel familiar straight away, because that is what disposables used.
Which should you choose?
- Coming off disposables or smoking: nic salt, usually 20mg, in a pod kit.
- Light or occasional user: nic salt at 5mg or 10mg, or freebase at 6mg.
- Want big clouds from a sub-ohm tank: freebase at 3mg or 6mg.
- Not sure what your device is: if it has a small pod and a single button or draw activation, treat it as a nic salt device.

Questions readers ask
Is nic salt or freebase better?
Neither is better overall. Nic salt suits pod kits and higher strengths; freebase suits lower strengths and sub-ohm tanks. Pick based on your device and how much nicotine you need.
Does nic salt hit harder than freebase?
No. At the same strength, freebase gives a sharper throat hit. Nic salts feel smoother, which is why they are sold at higher strengths.
Can I use freebase in a pod system?
Yes, at lower strengths such as 6mg or 12mg. Many pod users switch to nic salts because higher freebase strengths feel harsh.
Can I use nic salts in a sub-ohm tank?
It is not recommended. Sub-ohm tanks produce a lot of vapour, so a 10mg or 20mg nic salt would be far too strong.
Which lasts longer, nic salt or freebase?
In a pod kit, a 10ml nic salt usually lasts longer because you take smaller draws. See how long a 10ml nic salt lasts for typical numbers.
Is nic salt or freebase better for flavour?
Both carry flavour well. Nic salts are usually 50/50 PG to VG, which keeps flavours sharp in a pod kit. High-VG freebase shortfills trade a little flavour for bigger clouds.
