The popularity of e-cigarettes has grown a lot in recent years, and with the rapid increase in the number of vapers worldwide, vaping seems to be the latest viral craze. With the growth of vapers, so too has the availability of different flavours to suit the preferences of each user exploded. There are tons of varieties of vape juice one can choose from – from fruit to menthol, candies to cakes, and many more variant and distinct tastes. But aside from flavouring, what exactly is in your vape juice? In this article we’ll investigate the key vape juice ingredients that make for a happy vaping experience – and the ones you should avoid at all costs.

There are five basic vape juice ingredients: (1) PG or Propylene Glycol, (2) VG or Vegetable Glycerine, (3) Nicotine, (4) Water, and (5) Flavouring.

Propylene Glycol

One of the main ingredients in e-liquid is Propylene Glycol or PG. PG is a colourless and odourless laboratory-made liquid that’s used in many flavourings. It is FDA-approved for human ingestion and is considered safe in food, drugs, and cosmetics.

It is an excellent carrier of flavour though it does not produce as much vapour as Vegetable Glycerine or VG. PG not only enhances flavour, it also leaves a stronger taste in the back of the throat, or what we commonly call “throat-hit.” Many vapers love this sensation and it is for this reason that they choose PG vape juice.

Vegetable Glycerine

As with PG, Vegetable Glycerine is also odourless and colourless. It has a slightly sweet taste and is also viewed as safe by the FDA. It is derived from vegetables, typically soybeans or palm trees.

Although it does not leave the same lingering flavour as PG and it has a smoother throat hit, many vapers still prefer VG because of the bigger and denser clouds of vapour it produces.


Nicotine content in vape juice varies. Although most vape juice contains nicotine, vapers also have the option to go for zero nicotine vape juice for non-nicotine vaping. Vape juice bottles display nicotine level in mg/ml, meaning that millilitre of vape juice in the bottle has that milligrams of nicotine. You just need to choose the mg amount based on your current smoking habits and your tolerance. If you’re trying to quit smoking, your goal should be to decrease your nicotine amounts over time. Nicotine levels also affect the throat hit sensation of your e-juice.

Not all nicotine are of the same quality. For better vaping experience, your vape juice should have nicotine that is of the highest purity.


There are several available vape juice flavourings, ranging from fruity flavours to desserts to other unique flavours. These delicious flavours come from quality food ingredients and flavourings. VG and PG alone do not have much of a flavour, but when mixed with delicious additives, you get nice, strong flavours. Flavourings are added to enhance the taste and experience but they only make up a small percentage of vape juice, no more than 10% of the total vape juice content.

Although these basic ingredients are readily available in the market, you can’t just go mixing and matching the ingredients unless you absolutely know what you’re doing. As vape juice is something that is ingested, you need to make sure that you only buy quality made e-liquid. Premium vape juices use ingredients that are of high-quality and thus are safe for human consumption.

Though regular juices are more affordable, they may contain chemicals that are not safe to be consumed. At LWV, we pride ourselves on putting out top-grade, lovingly crafted flavours made with only the highest quality vape juice ingredients.
