What's Inside Your E-Liquid?

Whether you're new to vaping or have been choosing it as a smoking alternative for a while, you're likely not familiar with the components that actually make up the liquid that you inhale. Luckily for you, this blog post will teach you everything there is to know about what's inside your premium Smoko e-cigarette.

The two main ingredients

There are two main ingredients that make up your vaping liquid. These are propylene glycol, or PG, and vegetable glycerin, commonly referred to as VG.


Out of the two ingredients used in e-liquids, PG is considered to be the more popular choice for smokers as it replicates the "throat-hit" they're used to when smoking. PG has no odour or colour, and is a chemical that lasts longer between coil changes due to its lower density. PG also holds flavour better than VG, and so is more liked by those that crave a strong taste from their vape refills. However, one downside to PG is that it has a wider range of allergic reactions than VG does - ranging from anything like a tingling throat sensation to a dry mouth that might be unpleasant for some.


VG is known to be thicker than PG, lending to smoother consistencies and a more subtle flavour. It also produces more vapour than PG. However, the thicker consistency does mean that your tank may need cleaning more than usual, and it also can increase phlegm production at the back of some smokers' throats. VG also has a sweeter taste, and so is perfect for those with a sweet tooth. It also causes far fewer allergic reactions than have been reported with PG, so might be the better option for those that are sensitive to a lot of allergens.

Which one should I choose?

Ultimately, what you choose to fill your vape with is up to you. Do you want to prioritise tank maintenance or flavour? The throat-hit or vapour production? It should be noted that many e-liquid suppliers such as SMOKO offer a combination of the two components in order to reap the benefits of each and minimise the downsides. One of the most ideal combinations we've found is 70-30 VG-PG.
