    Nic Shot Highlights:

        • Shortfills are large bottles of e-liquid, sold with zero nicotine

        • Adding nic shots to e-liquid requires unflavoured nicotine boosters of 20mg

        • Generally you cannot create more than 3mg overall nicotine strength

        • Government vaping regulations (TPD from May 2017) dictate why bottles bigger than 10ml have 0mg nicotine.

      The reason why more people are making their own DIY e-juice and mixing shortfills is down to the TPD regulations that came into play back in May 2017. Regulations meant that retailers can no longer sell 30,60,100ml juices unless they are nicotine-free.

      What is a nic shot?

      A nic shot is a flavourless liquid that you can mix to your own bigger bottle of juice. This allows you to get around the 10ml juice restriction and enjoy those larger, and often more cost-effective, bottles. 

      A nic shot contains a concentrated amount of nicotine, which is designed to be added to a DIY juice or a shortfill. It is not intended to be vaped without being added to another juice. 

      What’s a shortfill?

      How to add a nic shot to a shortfill

      A shortfill is a bottle of high vg e-liquid filled just below the top level to allow you to shake and vape a nic shot into it. For example, a 60ml shortfill will be filled to 50ml to allow the space for a 10ml nic shot if required.

      More and more brands are creating shake and vape style liquids, such as Doozy and IVG. The shortfills are higher in VG, meaning that they’re best suited for a sub-ohm, big cloud kit, rather than a starter device. 

      You might choose to go down the route of adding your own nic shot to a short fill if you don’t want to carry around lots of 10ml bottles or if you want to save some money. 

      How do I add a nic shot to a shortfill?

      As the shortfill contains less e-liquid then you have space to add a 10ml nic shot. Shake it up, then you are ready to fill your tank. Just make sure the nicotine is properly mixed into the ejuice. Read on for how to make your shortfill 6 or 9mg. 

      What about adding nic shots with DIY e-liquid?

          How do you add nicotine shots to get the right strength?

          You’ll need to do a little bit of basic maths to get your desired strength of e-liquid.

          3MG liquid by adding nicotine shots:  

              • 30 ml bottle of juice = ½ 10ml bottle the nicotine shot

              • 60 ml bottle of juice = 1 x 10ml bottle of nicotine shot

            6MG liquid by adding nicotine shots:

                • 30 ml bottle of juice  = 1 x 10ml bottle the nicotine shot

                • 60 ml bottle of juice  = 2 x 10ml bottle of nicotine shot

              9MG liquid by adding nicotine shots:

                  • 20 ml bottle of juice  = 1 x 10ml bottle the nicotine shot

                  • 60 ml bottle of juice  = 3 x 10ml bottle of nicotine shot

                When you add nicotine shots you can get creative and come up with your own blend of PG:VG along with the amount of nicotine you take.

                If you add too many nic shots then you can lose flavour. This is because the flavourless liquid of the nic shot dilutes it. However, there is a hack to combat this. 

                    • Get yourself an empty chubby bottle so there is space to add 20ml more e-liquid and shake it up. 

                    • Add a 10ml nic shot 

                    • Find an e-liquid with a similar flavour profile in 10ml with an 18mg nicotine content.

                    • Add this to the chubby bottle.

                    • Give it a shake.

                    • Vape your 6mg.

                  Doing it this way prevents you from losing flavour. You might even find that you can create something incredible by mixing another flavour with your shortfill. Get creative or keep it simple.
