Nicotine free vape juice is e-liquid made without any nicotine, sold as 0mg e-liquid. It has the same base as any vape juice, propylene glycol (PG), vegetable glycerine (VG) and flavourings, just with no nicotine added. Because UK limits on bottle size apply only to nicotine-containing liquid, 0mg vape juice is the only kind you will see in 50ml and 100ml bottles. Every nic salt we list on this site contains nicotine; the lowest strength we cover is 5mg.
What is in 0mg e-liquid
Take nicotine out of an e-liquid and three ingredients are left. The balance between them decides how a 0mg liquid feels and which devices it suits.
| Ingredient | What it does |
|---|---|
| Propylene glycol (PG) | Carries flavour and gives the throat sensation |
| Vegetable glycerine (VG) | Thicker; makes the visible vapour |
| Flavourings | Food-grade flavour concentrates |
Most nicotine-free vape juice is sold as high-VG liquid, often 70/30 VG to PG, because it is aimed at sub-ohm tanks that make large clouds. That is a different product from a 50/50 nic salt. Our PG/VG ratio guide explains why the mix matters for your device.
Nicotine-free e-liquids vs nicotine e-liquids
Apart from the nicotine, the two are made the same way. Nicotine-free e-liquid uses the same PG, VG and flavourings as nicotine e-liquids; the difference is that nothing is added to give a nicotine strength. On a bottle you will see it labelled 0mg, zero nicotine or nicotine-free. A nicotine vape juice shows its strength in mg per ml, and in the UK every nicotine liquid also carries the health warning that nicotine is highly addictive.
Throat hit is the other difference vapers notice. Nicotine adds a catch at the back of the throat, so a 0mg vape liquid usually feels softer. Some people miss it and some do not, which is worth knowing before you switch.
Why 0mg vape juice comes in big bottles
UK law limits nicotine e-liquid to 10ml bottles and 20mg/ml. Regulation 36 of the Tobacco and Related Products Regulations 2016 sets those limits for nicotine-containing liquid. A liquid with no nicotine is not covered by the 10ml cap, so brands sell 0mg e-liquid in larger bottles, and shortfills exist because of it.
Shortfills
A shortfill is a bottle of 0mg e-liquid that is deliberately not full: for example 50ml of liquid in a 60ml bottle, or 100ml in a 120ml bottle. The empty space leaves room to add a 10ml nicotine shot if you want one. Without a shot, a shortfill is simply nicotine-free vape juice.
Nicotine shots
A nicotine shot is a 10ml bottle of unflavoured liquid containing nicotine, usually at 18mg or 20mg. Adding one to a shortfill brings the whole bottle to a low strength, around 3mg in a 60ml bottle. That is how people get large bottles of low-nicotine freebase liquid. It is a different route from nic salts, which are sold ready-made in 10ml bottles. Our e-liquid calculator works out how many shots a shortfill needs for the strength you want.
| 0mg shortfill | Nic salt (what we cover) | |
|---|---|---|
| Nicotine | None, unless you add a shot | 5mg, 10mg or 20mg per ml |
| Bottle size | 50ml to 100ml (often more) | 10ml (legal maximum for nicotine) |
| Typical mix | High VG, often 70/30 | 50/50 PG to VG |
| Made for | Sub-ohm tanks, direct-to-lung | Pod kits, mouth-to-lung |
Can you use nicotine-free vape juice in a pod kit?
You can put 0mg liquid in a refillable pod, but the usual high-VG shortfill is thick and can struggle to soak into the small coils in a pod. The result is often dry, weak puffs. If you want low nicotine in a pod kit, a 5mg nic salt at 50/50 is built for the job. If you specifically want zero nicotine in a pod, look for a 50/50 0mg liquid rather than a cloud-chasing shortfill.
The difference between salt and freebase nicotine is covered in nic salt vs freebase, and our guide to vape pods explains how pod coils work.
Vape kits and coils for 0mg liquid
Most nicotine-free e-liquids are high VG vape juice made for a sub-ohm vape kit: a larger device with a tank and low-resistance vape coils that heat thick liquid quickly. In a small pod kit, that thick liquid can starve the coil. If you plan to vape without nicotine in a pod, check the PG/VG mix on the bottle first. Our vape coils guide explains which coil resistances suit which liquids.
Choosing a nicotine-free vape liquid flavour
Because shortfills come in big bottles, flavour choice matters more than it does with a 10ml. Many vapers buy a 10ml nicotine version of a flavour first, then move to the 0mg shortfill of the same vape juice flavour once they know they like it. The same flavour families apply either way: fruit, menthol, sweets, desserts and tobacco. Our flavours hub groups the nic salt versions so you can see what each family covers.
Why some people vape 0mg
People choose nicotine-free vape juice for different reasons: some have stepped their nicotine down over months and reached zero, others only ever vaped for the flavour. We do not make any claims about health either way. What we can say is that stepping down works best one strength at a time, which is easier when you keep the same flavour. Our strength guide sets out the steps from 20mg to 10mg to 5mg.
Stepping down your nicotine strength
For vapers who want to reduce their nicotine intake gradually, the route usually runs through the nicotine strength steps rather than straight to zero: 20mg, then 10mg, then 5mg, staying on each for a few weeks. With nic salts that means changing bottle strength while keeping the same flavour. Reaching 0mg after that usually means a different kind of liquid, since nic salts are not generally sold without the nicotine.
The 18+ rule now covers nicotine-free vapes
Until recently the UK age-of-sale law applied to nicotine vapes. Under the Tobacco and Vapes Act, from 29 October 2026 it is an offence to sell any vaping product to someone under 18, including nicotine-free vapes and 0mg e-liquid. The government set this out when it extended the under-18 sales ban to all vapes. Our wider UK vape rules guide covers the other limits.
Every product on Vapour is for adults aged 18 and over. Every nic salt we list contains nicotine, which is addictive.
If you are looking for the lowest nicotine we cover
Our catalogue is nic salts only, so there is no 0mg option here. The lowest strength is 5mg, and plenty of flavours come in it across Elfliq, Elux Legend and Bar Juice 5000. Browse every 5mg nic salt, or the full nic salt list by flavour.
Questions readers ask
Is nicotine-free vape juice legal in the UK?
Yes. It can be sold to adults, and since 29 October 2026 it is an offence to sell it, or any vape, to under-18s under the Tobacco and Vapes Act.
What does 0mg mean on vape juice?
0mg means the e-liquid contains no nicotine. The number on a bottle is the nicotine content in milligrams per ml.
Why is 0mg e-liquid sold in 100ml bottles?
The 10ml bottle limit in the Tobacco and Related Products Regulations 2016 applies only to nicotine-containing liquid. Nicotine-free liquid can be sold in larger bottles, usually as shortfills.
Can I add nicotine to a 0mg shortfill?
Shortfills leave space for a 10ml nicotine shot, which turns the bottle into a low-strength freebase liquid. That is a different product from nic salts.
Do you sell nicotine-free nic salts?
No. Every nic salt we cover contains nicotine. The lowest strength is 5mg.
Can I put nicotine-free vape juice in a pod kit?
You can, but high-VG shortfills are thick for pod coils. A 50/50 liquid wicks better in a pod. See the PG/VG ratio guide.
