Nicotine shots are small 10ml bottles of concentrated, unflavoured nicotine designed to be added to shortfill e-liquids. They let you control exactly how much nicotine ends up in your final mix, without touching the flavour profile of the shortfill you’ve chosen. Most UK nic shots come in either 18mg or 20mg strength, with different VG/PG ratios to suit different kits. Whether you’re a switcher building your first shortfill setup or an experienced vaper who wants to fine-tune nicotine levels on a budget, nic shots give you that control simply and cheaply.

Adding a nic shot to a shortfill is one of the most cost-effective ways to vape in the UK. Here is why vapers consistently choose this approach over buying pre-mixed nicotine e-liquid:
If you want to understand more about whether shortfills and nic shots actually save you money, we’ve broken the numbers down in detail in our vaping vs smoking cost guide.
Not all nic shots are the same, and the type you choose makes a real difference to how your finished mix vapes.
For a deeper look at how these two nicotine types compare day to day, see our guide on nic salts vs freebase nicotine.
Nic shots suit a wide range of vapers, but they’re particularly useful for a few specific groups.
Switchers coming off cigarettes often find shortfills on their own too low in nicotine. Adding a nic shot bridges that gap without needing to buy separate pre-mixed bottles. If you were smoking 20 a day, most switchers find 3mg in a sub-ohm kit or 10-20mg in a pod kit gives them enough to manage cravings – our nicotine strength guide walks you through choosing the right starting point.
Everyday vapers who have settled on a shortfill flavour they love will use nic shots regularly. It’s the cheapest way to keep vaping the same liquid without compromising on nicotine satisfaction.
Enthusiasts mixing their own blends also rely on nic shots as a controlled way to add nicotine without introducing flavour variables into a custom mix. The same logic applies to anyone experimenting with longfill e-liquids, which involve a similar mixing process on a larger scale.
This is the question we get asked most, and the answer depends on three things: the size of your shortfill, the strength of your nic shot, and the final nicotine level you want.
The maths is straightforward once you see it laid out. The table below covers the most common combinations, using both 18mg and 20mg shot strengths.
A note on the ceiling: you can technically add more shots to push the nicotine level higher, but adding too much volume dilutes the flavour significantly. Six milligrams is about the maximum most vapers find workable in a standard shortfill without the taste suffering noticeably. If you need nicotine levels above 6mg regularly, you’re better served by pre-mixed 10ml bottles or switching to a MTL pod kit with a higher-strength e-liquid. Our shortfill guide covers this in more detail.
Getting the VG/PG ratio right is something a lot of people skip over, and it’s the most common reason a shortfill vapes differently after mixing.
The principle is simple: match the ratio of the shot to the ratio of the shortfill as closely as possible.
Sub-ohm and high-VG shortfills are typically 70/30 VG/PG or higher. Adding a 50/50 shot introduces a significant amount of extra PG, which thins the liquid. The result is less vapour, weaker flavour density and a sharper throat hit. Use a 70/30 shot instead and the finished liquid stays consistent with what you bought.
MTL devices and lower-wattage kits use thinner liquids because tight coils and smaller wicking ports need PG to flow efficiently. A 50/50 shot suits these setups well.
If you’re not sure what your shortfill’s ratio is, check the label. Most UK shortfills state it clearly. For a full breakdown of what VG and PG actually do to your vape, see our guide on VG and PG explained.
The choice between freebase and nic salt shots comes down to your kit and how you want nicotine to feel.
Freebase nic shots use the traditional form of nicotine. At lower finished concentrations like 3mg, the throat hit is mild and suits most vapers. Push beyond 6mg with freebase and it starts to feel harsh, particularly in sub-ohm kits running at higher wattages.
Nic salt shots use a form of nicotine that absorbs faster and feels smoother at higher concentrations. They’re the better option if you’re mixing a shortfill to use in a pod kit or MTL device at 10mg or above.
One important caveat: nic salt shots used in high-power sub-ohm setups can feel uncomfortably intense. The faster absorption that makes salts smooth in a low-wattage pod becomes too much in a device running at 50W or more. If you’re using a sub-ohm kit, stick to freebase shots. If you’re on a pod kit or MTL device, nic salt shots are worth considering. Browse our nic salts range for compatible pre-mixed options if you’d rather skip the mixing step entirely.
Mixing is quick, but there’s a right way to do it. Here’s the process we use every time:
That’s the full process. If you’ve ever mixed a shortfill and thought the flavour tasted flat immediately after, skipping step four is usually the reason.
Honestly, yes – a little. Adding any volume to a shortfill dilutes it slightly. A standard 50ml shortfill is formulated to fill 60ml once a 10ml shot is added, so the flavour is designed to account for that dilution. You should not notice a meaningful difference in taste when you mix correctly.
Problems arise when people add too many shots. Adding two shots to a 50ml shortfill to hit 6mg brings the total volume to 70ml in a 60ml bottle, which overfills it and over-dilutes the flavour. If you want a higher finished nicotine level without sacrificing taste, a higher-strength shot (20mg rather than 18mg) lets you reach a similar end result with slightly less volume added.
Matching the VG/PG ratio of the shot to the shortfill also helps. A 70/30 shot in a 70/30 shortfill keeps the liquid’s texture and cloud output consistent. Swap in a 50/50 shot and you’ll notice the vape feels thinner and the flavour less full.

One 10ml shot. This brings the total volume to 60ml – the standard finished size for a 50ml shortfill. Using one 18mg shot gives you approximately 3mg in the finished bottle. One 20mg shot lands at approximately 3.3mg.
Freebase shots use the traditional form of nicotine and produce a stronger throat hit, particularly at higher concentrations. Nic salt shots use a modified form of nicotine that absorbs faster and feels smoother. Freebase suits sub-ohm kits; nic salt shots suit MTL and pod devices. For more detail, read our nic salts vs freebase nicotine guide.
Technically, yes. Practically, it’s a bad idea. Unflavoured nic shots taste peppery and unpleasant on their own. They’re designed to be added to shortfills, not vaped neat.
Match it to your shortfill as closely as possible. High-VG shortfills used in sub-ohm kits work best with 70/30 shots. MTL setups and pod kits are better suited to 50/50 shots, which wick more efficiently through tighter coils.
With one 18mg shot in a 50ml shortfill, the finished 60ml comes out at approximately 3mg. With one 20mg shot, approximately 3.3mg. Adding two 18mg shots to a 50ml shortfill gives roughly 6mg. This is close to the practical maximum before flavour dilution becomes a problem.
Slightly, but a correctly formulated shortfill accounts for this. The flavour concentrate in a 50ml shortfill is designed to fill 60ml, so adding one standard shot should not noticeably weaken the taste. Adding too many shots, or mismatching VG/PG ratios, is where flavour suffers.
Around 6mg is the practical ceiling for a 50ml shortfill. Beyond that, you’re over-filling the bottle and the flavour dilution becomes obvious. If you need higher than 6mg, pre-mixed 10ml bottles are a better option.
Yes, in most cases. Shortfills cost less per ml than equivalent pre-mixed bottles, and a nic shot adds a minimal cost on top. The more you vape, the more the savings compound. Our vaping vs smoking cost guide runs the numbers in full.
Check your device. Sub-ohm kits running at higher wattages work with freebase shots. Pod kits and MTL devices are better suited to nic salt shots, which deliver nicotine smoothly at lower power settings. Using nic salt shots in a high-wattage sub-ohm kit can feel harsh and overpowering.
Shake the shortfill, add the shot, replace the cap, then invert and roll the bottle gently for 30 seconds. Leave it for 30 minutes before vaping. This short steep lets the nicotine bind properly and the flavour settle after the dilution.
Yes. UK-sold nic shots must comply with TPD regulations, which cap nicotine concentration in e-liquid at 20mg/ml. All shots we stock meet this requirement and are sourced from regulated UK manufacturers.
Most nic shots contain nicotine, propylene glycol (PG), vegetable glycerine (VG) and water. They contain no flavouring. The PG/VG ratio varies by product, which is why checking the ratio before you buy matters for matching to your shortfill.
