What is E-Juice?
People who are not familiar with vaping devices and their accessories often ask one question: “What is e-juice?” Well, in simple terms, e-juice or e-liquid refers to the component of e-cigarettes that produces the vapour and accounts for the flavours. When a vape pen is being used, the battery provides the energy that’s needed to heat the e-juice and turn it into an aerosol (vapour) for its user to inhale.
E-liquids give vapers limitless opportunities to experiment with different flavours and also enjoy the experience of nicotine if they so desire. While electronic nicotine delivery systems (ENDSs) usually contain nicotine, not all electronic cigarettes use nicotine-containing e-juices.
What e-juices (e-liquids) are made up of
Reputable e-juice manufacturers often list the chemical content of their vape juices as required by EU laws. Ever since e-cigarettes became popular in modern society, there have been a number of myths surrounding their uses and effects.
However, electronic cigarettes are legal products in countries such as Canada, the UK, as well America. The scientific community has been researching the long-term impact of vape substances on users for some time now. To find the answer to the question “What is e juice?”, here is an overview of the 4 base ingredients of e-liquids.
Vegetable Glycerin (VG)
E-juices used in modern atomizers may contain up to 80% VG by volume. Glycerin is a naturally sourced substance that’s obtained from fat. The glycerin in e-liquids is produced from vegetable oils, hence it’s known as vegetable glycerin. However, this is rather counterintuitive as VG is an alcohol, not an oil. This same fact makes it relatively safe for people to inhale VG. It’s a non-poisonous colourless liquid with no smell, but a good taste.
Propylene glycol (PG)
Some vape juices contain more PG than VG. Propylene glycol works well in older atomizers because its viscosity is low. Similar to VG, PG is also classified as an alcohol. While propylene glycol is almost odourless, it gives a faintly sweet taste. PG is often added to food, medicine and other products to preserve their moisture. It’s also believed that PG forms a key component of antifreeze. A small number of vapers are sensitive to PG. So, if your e-juice with high PG makes you feel sick, switch to one with high VG.
The good news about vapes is the wide variety of flavours that are available on the market. E-liquids don’t have much taste on their own. So, it makes sense for vape makers to add flavourings to their products. E liquids are flavoured with food-grade additives. However, there are serious concerns about additives that are not healthy. Stick to flavoured e-juices from trusted manufacturers to decrease your risks of inhaling unhealthy additives.
As discussed earlier, the majority of e-liquids contain nicotine. Nicotine delivers a good throat hit to vapers. Moreover, it allows them to satisfy their nicotine cravings without smoking combustible cigarettes. Nicotine can be toxic in large doses. So, you may want to avoid extra strength e-liquids.
