E-Juice Nicotine Levels Explained
One of the most common questions we are asked both by email and on the phone is:“How much nicotine should I put into my e-juice?”When trying to explain e-juice nicotine levels, it is important to remember that it is entirely down to preference. There is no ‘correct’ level of nicotine, and you should experiment to find the amount that suits your needs and will help you to achieve the ultimate goal of quitting smoking.
What is nicotine?
Nicotine is a colourless or slightly yellow oily liquid which is the main constituent of tobacco. It is absorbed through the skin and the mucosal linings in the nose, mouth and lungs, travels through the bloodstream and reaches the brain in about 7 seconds. In small doses, it acts as a stimulant however it can block the action of nerves and skeletal muscle cells in high quantities.It is highly addictive and is mostly consumed through cigarette smoking; which is why you are on this page right now, making the switch to vaping! We all know how dangerous cigarettes are due to the tar and sheer quantity of extra chemicals added to them from horrid sources, but an e-cig containing just 4 ingredients including nicotine, which wouldn’t cause you serious health problems in the quantities you would be consuming without the combustion process? Not so bad.
Explain the numbers to me.
Okay, if you are asking this question, you probably will be confused when you read something like ‘50ml VG Nicotine 72mg’. While it may look like a terrifying string of symbols which don’t make much sense, it’s easy to understand once you break it down.‘50ml’ is simply how much you have in your bottle; but I’m sure you already got that one. ‘VG’ means that the nicotine is based in vegetable glycerine; it could also be based in PG, or propylene glycol. This is done so that you do not have to handle raw nicotine, and so that it comes in liquid form. The nicotine is diluted to create a more manageable solution to add to your vape, the same way you would dilute squash in water before you drink it (but please do not drink nicotine!).‘72mg’ is how much the nicotine was diluted. It is given in terms of how many milligrams of nicotine there are in a millilitre of the solution. Thus, 72mg means there are 72 milligrams of nicotine in 1 millilitre of the nicotine solution. So to summarise, ‘50ml VG Nicotine 72mg’ means ‘50ml of nicotine which has been diluted in VG enough for there to be 72mg of nicotine in each ml’.
Nice! So how much nicotine do I need?
If you have gotten to the point where you are ready to add your own nicotine and get the right e-juice nicotine levels, you probably already know the nicotine strength you like to vape at. For reference, in a cigarette there is roughly 8-24mg of nicotine, which averages to 12mg. However, you only absorb around 1-2mg of this, so that might give you a good idea of where to start. Right now, my preference of nicotine is 3mg.So let’s say I’m making 10ml of e-liquid. What you are essentially doing here is diluting the nicotine further until it reaches the strength that you want. If I added 10ml of my nicotine, I’d still have 72mg strength because nothing has changed. Now if I fill my bottle with 5ml of other ingredients and then have 5ml of nicotine, I have halved the strength to 36mg, and so forth. So how do I work out how much to add in order to get 3mg?The formula for working this out is (target strength / base strength) * amount of e-liquid to make. The target strength / base strength tells us how much nicotine there would be in 1ml in order to have a 3mg strength, so we need to multiply that by 10 to tell us how much nicotine needs to be in 10ml in order to have a 3mg strength. The calculation we would do in this situation is (3 / 72) * 10, which is 0.42. So I will add 0.42ml of nicotine into my solution, and hoorah! I have a 3mg nicotine strength.
Phew, that was a lot to take in!
It might seem daunting, but it’s so simple once you’ve given it a go. To make things even easier, there are plenty of online e-liquid calculators ready for you to punch in the numbers and do the ‘heavy lifting’ for you.At the very least, you have some idea of how e-juice nicotine levels are calculated for e-liquid.
