Accessing Nicotine

It is illegal to trade liquid nicotine in any way in Australia, so you won't find any nicotine products on this Australian site. It is legal to purchase nicotine online from overseas though. So to get around this we created a sister company in New Zealand that you can purchase nicotine products from, you'll find the unflavoured freebase nicotine and salt nicotine for mixing here.


  • Nicotine is a poison and must be treated with care, especially in high concentrations.
  • Always wear gloves when handling nicotine, 100mg/ml is a high concentration and can absorb through the skin very quickly if spilt, resulting in the equivalent of hundreds or thousands of cigarettes worth of nicotine being absorbed in a very short amount of time.
  • Avoid getting near the eyes and mouth.
  • Always use measuring syringes to ensure the correct amount is added.
  • Always store where children cannot access it, preferably locked away. Nicotine base is a poison and can be lethal if ingested.

Nicotine Calculator

We have a nicotine calculator that you can use here:


Today we will be explaining how to add nicotine to an RTV (ready to vape) flavour bottle, so ensure that you are on the ready to vape tab at the top of the calculator and not the doubler tab.

Let’s explain what we’re looking at in the above image:

  1. Here you need to enter the strength of your nicotine base, if it is purchased from Wick & Wire Co NZ it will be 100 (100mg/ml). Even though 100mg/ml is the most commonly available strength there are other strengths, so always check the labelling on your nicotine bottle and ensure you fill out this field correctly.
  2. Here you need to enter the volume of the flavour bottle that you’re mixing into, we’ve used 60 (60ml) as an example here.
  3. Here you need to enter your desired finished nicotine strength, we’ve used 3 (3mg/ml) as an example.
  4. This is the output that’s been calculated from the numbers we have entered above. This is how many millilitres of nicotine base to add to your flavour bottle. In this example, it’s telling us to add 1.86ml of nicotine base to the bottle of flavoured e-liquid. Please note that this amount is not the same for every bottle size and strength, it changes depending on the data we have given to the calculator.

Please note that whether you're using freebase nicotine or salt nicotine, the mixing ratio is the same.



There are usually two caps on an e-liquid bottle, an outer cap and an inner cap (with a nozzle). We must remove the inner cap to add nicotine to the bottle. This can be difficult as they’re quite tight to ensure a good seal, we do have a tool available that makes it much easier though, you can find it here.

Depending on how much nicotine base we’re adding, and how full the flavour bottle is, you might find that you need to remove some flavoured e-liquid to fit the nicotine base in. Always use separate measuring syringes for coming into contact with the nicotine base and the flavours, using the same syringe for both will result in contamination of the nicotine base.

Carefully draw the correct amount of nicotine into a measuring syringe and add it to the bottle of flavoured e-liquid. Once the nicotine base has been added, replace the bottle caps tightly and shake vigorously for several minutes. This step is crucial as we must ensure that the nicotine is mixed into the e-liquid thoroughly.

Discard the used syringe or syringes, these are single-use items.

Once the nicotine has been mixed, leave it to settle for 24 hours. Before adding any e-liquid to your atomiser, give the bottle a shake.

If you have any further questions please don’t hesitate to contact us, we would rather you be confident than begin this process unsure of yourself.
