What’s in an E-Cig Juice

Many people who are interested in vaping and e-cigarettes, as well as those who are already vaping on a regular basis, may wonder what exactly is in the e-cig juice that they’re using. This is definitely a valid concern because you are, after all, inhaling the vapour that’s created by the e-liquids you purchase.

If you’re concerned about what’s going into your body, continue reading to learn about the ingredients in e-cig juice, as well as some interesting information about nicotine.

The Base of E-Cig Liquids


The base of e-liquids usually consists of a few ingredients:

  • Polyethylene Glycol 400: Also commonly referred to as PEG-400, this ingredient is a great alternative for those who are sensitive to propylene glycol, which is also commonly found in e-liquids, food items, and pharmaceuticals. PEG-400 is made from animal oils or from petroleum oils. In terms of the flavour and odour of this ingredient, opinions vary. Some individuals prefer the taste of this ingredient, describing it as flowery, creamy, and oily. Others, however, find that it actually lacks an odour and a flavour altogether.
  • Propylene Glycol: This ingredient is also referred to as PG, for short. It’s produced from petroleum-based oils or animal oils. And it’s described as clear and colourless, as well as somewhat syrupy in texture when it’s stored at room temperature. In order to produce a vapour, it needs to be shaken vigorously or heated. It’s also the ingredient responsible for what e-cig smokers call the throat hit. Otherwise, it’s flavourless and odourless.
  • Vegetable Glycerine: This ingredient is commonly derived from plant-based oils, making it ideal for consumers who don’t wish to purchase ingredients derived from animals or petroleum, and it’s actually a carbohydrate. Often used in cosmetic products and as an ingredient to add sweetness to food, when it’s used in an e-cigarette, it produces more vapour than propylene glycol does. However, unlike propylene glycol, it doesn’t produce a powerful throat hit. When compared to propylene glycol in terms of texture and flavour, vegetable glycerine is a bit sweeter and thicker.



Many people choose to switch to e-cigs when they’re trying to quit smoking traditional cigarettes. And in order to make the transition a success, e-liquids are infused with nicotine so that the body can fulfil its cravings. But what exactly is nicotine?

Put simply, nicotine is the addictive stimulant found in traditional cigarettes. The great thing about e-liquids is the fact that you can find a variety of nicotine strengths so you can gradually reduce your dependency on this substance until you can finally move on to nicotine-free e-liquids.

When it comes to choosing e-liquids that do contain nicotine, vapers have several choices that include 36mg, 24mg, 18mg, 16mg, 12mg, 10mg, and 6mg.



E-liquids come in a variety of delicious flavours so that vapers can choose the tastes that they prefer. These include everything from floral to fruity options.

It’s necessary to add these flavourings because nicotine has no taste. Also, the added flavour makes the vaping experience more enjoyable. So whether you prefer a flavour that reminds you of your favourite dessert, or you long for a traditional tobacco flavour, there are manufacturers who produce a variety of e-liquids to choose from.

It’s important to note that an ingredient called diacetyl should be avoided completely, as it can cause damage to the lungs when it’s inhaled. Therefore, avoid any e-liquid flavours containing this harmful ingredient.

More Interesting Facts About Nicotine


Many people don’t realise that nicotine is actually considered therapeutic. In fact, it can be used to treat several conditions, including attention deficit disorder, Parkinson’s disease, Alzheimer’s disease, Tourette syndrome, inflammatory skin conditions, obesity, and sleep apnoea.

Although nicotine is naturally occurring in some vegetables, such as peppers, potatoes, cauliflower, and green tomatoes, it’s in much smaller amounts than that found in cigarettes and e-cig juice.

However, despite the many benefits that it may provide to some individuals, it’s a highly addictive and toxic substance. The body physically craves it because it causes an effect similar to caffeine. Addiction to nicotine can also be compared to addictions to other drugs like cocaine and heroin, as well as alcohol. This is why it’s very difficult to quit once you start using nicotine, and you have to take smaller doses of nicotine over time in order to gradually wean yourself off of it if you don’t wish to quit “cold turkey.”

Nicotine products should always be kept away from children and pets. The estimated lethal dose for children is roughly 10mg. For an adult, the lethal dose is around 40mg to 60mg. To put it in perspective, a child can die from ingesting only 10 drops of e-cig juice at a strength of 24mg/ml, while an adult can die from 20 drops of 54mg/ml e-cig juice.

A Word About Making Your Own E-Liquid


Those who make their own nicotine-infused e-liquids need to be very careful. Always wear the right protective gear and get the right training to handle nicotine safely. Also, e-liquids should never be ingested, as they are poisonous.
