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 vape liquid that is heated and turned into an aerosol which is inhaled. 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 in E-Liquids
There are two main ingredients that make up your vaping liquid. These are propylene glycol, or PG, and vegetable glycerine, commonly referred to as VG.
PG - Propylene Glycol
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 - Vegetable Glycerine
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 you may need a more powerful device, 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 type of E-Liquid should I choose? High PG or High VG?
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.
Flavourings are added to the e-liquid to make the experience a pleasant one. In the UK and the EU there is good regulation in place for what ingredients can be used in E-Cigarettes.
You may well have seen some of the E-Cigarette ‘horror stories’ in the newspapers about the number of people suffering from EVALI – E-Cigarette and Vaping Associated Lung Injury. The crux of this particular matter is about what is being added to the e-liquid that is causing this kind of damage.
The Centre for Disease Control and Prevention (CDC) is aware of vaping related lung injury from adding illicit substances like THC (the psychoactive component in cannabis) to their e-liquid. In order to mix in the THC and keep the consistency, these people are using vitamin E acetate to add in the THC. According to the CDC, vitamin E acetate has been found in all samples of EVALI patients.
One flavouring that is known to cause damage is diacetyl. This is a flavouring that was used to flavour popcorn in popcorn factories, but the workers developed severe lung damage as it caused a disease named ‘bronchiolitis obliterans’ - aptly nicknamed ‘popcorn lung’. Sadly, the lack of strong regulation in the US and other countries has led to the inclusion of diacetyl as a flavouring.
