Vaping 101: PG vs VG E-Liquids

E Juice Splash 1

If you’re new to vaping you probably haven’t had an opportunity to experiment with different e-liquid flavours to decide on your favourite. Did you know that there’s more to experiment with than just flavours? There’s also a choice to be made when it comes to the base of your e-liquid and you’ve probably seen it be debated about time and time again on social media. It’s one of the biggest debates that rages on in the vaping community: PG vs VG.

So what are these two e-liquid bases and why are people so fiercely protective of their favourite? PG is the abbreviation of propylene glycol and VG is the abbreviation of vegetable glycerin. Combining one (or both) or these liquids with flavouring and nicotine (unless you opt for a 0% nicotine option) creates the e-liquid that you use in your e-cigarette. They provide the liquid base and produce vapour when heated in your device. Aside from these basic similarities, each offers different positives and drawbacks so you’ll find that most vapers have a strong preference for one type of liquid.

For today’s entry in our  Vaping 101 series for vape beginners, we’re going to clear the air around this ongoing debate and share both the pros and cons of each e-liquid base, as well as give you some insight about which type of e-liquid might be most suitable for your specific style of vaping.

PG E-Liquids - Throat Hit and Richer Flavour and Taste

As we mentioned before, PG stands for propylene glycol, which is a colourless, odourless by-product of petroleum. It has a runny consistency and packs an impressive throat hit, which is often deemed particularly important by new vapers. PG e-liquids are known for having the best flavour on the market and this is down to the PG itself, which is extremely effective at carrying flavour.

For their hefty throat hit and unparalleled flavour, e-liquids with a PG base are currently the most popular on the market. Additionally, the thinner consistency leads to less build up in your tank so you might notice your e-cigarette is cleaner than usual if you switch to a PG-based e-liquid.

You can find PG in many products you have in your house right now, including make up, shampoo, topical medical products, baby wipes and even asthma inhalers. While numerous studies have confirmed PG is safe for humans, you should proceed with caution if you have pets in your home. While PG is considered safe for dogs and is included in numerous dog foods, it is linked to disease in cats, so we’d recommend vaping away from your household pets if you use PG e-liquids.

VG E-Liquids - Smoother Vape and More Vapour

While PG e-liquids are all about flavour, VG e-liquids come into their own when it comes to vapour production. If you’re looking for billowy plumes of vapour then there’s no substitute for VG-based e-liquids.

Abbreviated from vegetable glycerin, VG is a natural derivative of vegetable oil, making it a suitable e-liquid option for vegetarians. It’s more viscous than propylene glycol so you’ll notice that VG e-liquids have a thicker consistency but they provide a smooth finish and, as mentioned above, produce unparalleled amounts of vapour. For this reason alone, they’re a firm favourite with cloud chasers and competitive vapers.

So, is it safe? As with propylene glycol, you’ll find vegetable glycerin in a plethora of household items, such as sweeteners, baked goods, toothpaste, bubble baths and hand creams. Toxicity studies have found minimal risk when it comes to VG and it’s a possible alternative for those who have an allergy to PG e-liquids.

What about a PG/VG blend?

What if you want the best of both worlds, can you blend PG and VG e-liquids? You can indeed, and it’s a popular option for those who find the throat hit from pure PG e-liquids too harsh, or find that the flavour from their VG e-liquids is lacking. Whether you opt for a 50/50 blend or a 75/25 split is up to you, so we’d recommend experimenting with different ratios until you settle on the best option for your personal vaping style.


So there you have it, an in-depth guide to PG and VG e-liquids. We hope this information helps you make an educated decision about your next e-liquid and you’re delighted with whichever option you settle on.
