Nicotine shots or Nic-shots are small bottles of flavourless liquid that are added to nicotine-free short fill e-liquids to increase or add nicotine.

When many people make the switch from smoking to vaping, prefilled vape juices might not have the nicotine strength you want. Mixing nic-shots into your e-liquid rather than relying on premixes can be a great way to create your own concentration.

Nic-shots became popular when the Tobacco Products Directive (TPD) came into force in 2017. Before then, when the vaping industry was only lightly regulated, manufacturers would make e-juices in larger premixed bottles. Now, TPD regulations require that nicotine-containing liquids can contain at most 20mg of nicotine per ml and come in bottles no larger than 10ml each.

In response, e-juice companies began selling their flavours as 0mg e-liquid. Because they contain no nicotine, these juices are not in breach of the TPD. Companies also began selling the flavourless and small 10ml 18mg nicotine bottles – called nic-shots – to mix in with the e-juice so that consumers can put nicotine into their vape juice.

In other words, nic-shots mean you can mix nicotine into large bottles of e-juice. The end result is the same as before TPD came into force, but requires you to do a bit of extra legwork. We at The Vaping Lounge have therefore written up a complete beginner’s guide to mixing in nic-shots to your e-liquid to make the process as simple and easy as possible.

Keep in mind most short fill e-liquids come in 120ml bottles containing only 100ml of juice, so you can easily mix your nic-shot with your e-juice in the same container. In other words, you can use the shortfill eliquid bottle to hold your postmixed vape juice!

Read the following to learn how to add nicotine juice to e-liquid:


Take a Pen and Mark Halfway Down the Nic-Shot.

That way you know where is half of a nic-shot, or 5ml. Then, mark half way between the line to have three lines on the bottle: a quarter-bottle line, a half-bottle line, and a three-quarter-bottle line.


Decide How Strong you Want your Nicotine Juice.

You should know what concentration your nic-shot is, and what concentration you want to end up with, before mixing the juice with your e-liquid. You can look up online an e-liquid calculator to work this out exactly, though we have produced a quick table to break down how much nic-shot you will need per 100ml:


18mg nic-shot strength 20mg nic-shot strength
3mg desired strength 20ml 18ml
6mg desired strength 50ml 43ml


Keep in mind that you will likely need more than one nic-shot bottle if you want to make more than 50ml of e-liquid or make a stronger e-juice.

Add your Nic-Shot to the e-Juice.

Unscrew your zero nicotine juice, and slowly add the nicotine shot into the bottle. As you start filling up the bottle, keep a note of how much you need to put in in the first place. Because you’ve drawn ‘quarter’ lines on all of your nic-shot bottles, you can keep a close eye on how much nic-shot you need to put in without fiddling with precise measurements. Make sure to add the nic-shot slowly, because once the nic-shot is in, you can’t take it out!


Start to Drip!

Screw the lid to the e-liquid back on, give the juice a shake to mix the nic-shot in, and you’re ready to start vaping some delicious vaping juice!
