What's the deal with all the liquids then?

VAPEHQ is currently changing its entire range of e-liquids. We're aiming for the highest quality of course.

High Quality products suit our site, in fact; that's all we want to stock really, but what's the difference between one liquid and another?

Essentially a liquid used in a vapouriser contains 4 main ingredients:

PG, VG, Nicotine, and Flavouring

Obviously, if that is all you are inhaling, it has to be more healthy than the 3000+ chemicals in a cigarette, right?

So what are PG, VG liquids, and what exactly am I inhaling?

The Short Version...

PG: Propylene Glycol

  • Food agent found in most liquids today, recognised as safe and usually mixed with a thickener.
  • PG gives a stronger throat hit than other liquid mixes and is the most common form of E-liquid available.
  • PG can cause irritation of the respiratory system in some people.

VG: Vegetable Glycerine

  • Food agent found in PG based liquids and also in 100% VG liquid form.
  • VG gives a weaker throat hit, can taste sweeter and produces more vapour than a PG based liquid.
  • VG is considered the more Organic/Natural choice of liquid by some people.

MG Rating

  • The mg rating of a liquid refers to the amount of Nicotine in it.
  • A higher rating gives a harsher throat hit and satisfies someone with a preference for stronger cigarettes.
  • Lower or even ZERO rated liquids are for people who enjoy a smoother vape, or want to slowly quit vaping altogether.


There is a lot of information on the web that can teach you all you need to know, but here are some basics:

PG: Propylene Glycol

PG: Propylene Glycol is used in the majority of liquids that people vapourise. It's clear and slightly sweet tasting, and has a higher viscosity (thickness) than water. It has been declared as "generally recognised as safe" for human consumption since the 1970's and we have all been ingesting it in various forms for years; in our foods.

Ever taken a tablet for a headache that has a shiny smooth coating? That's PG in one form.

PG is derived from Glycerin, which is in turn derived from vegetables, so you could call it organic, but there is definitely some lab work done to get to the liquid that people vape everyday.

Because the liquid is thicker than water, but not thick/viscous enough to vape on it's own; PG liquid is often combined with a thickening agent; such as VG: Vegetable Glycerin.

VG: Vegetable Glycerin

VG: Vegetable Glycerin is a food additive used to thicken things up and to help preserve them for a longer life.

It is a clear liquid, with a slightly sweet taste and has a higher viscosity than water, and PG.

Applications include sweeteners that you might choose over sugar in your coffee, or, quite literally; the icing on the cake!

It's used in e-liquids for vaping as a thickening agent, so as to prevent leaks and also as an alternative to PG majority flavours.

Considered by some to be a more natural/organic choice of liquid to vape.

Our current range of Pure E-Liquid is a 60% PG, 40% VG mix.

What's the nicotine MG rating all about?

As with your preferred cigarette brand, liquids can come in stronger or weaker varieties.

The Milligram rating (mg) on a liquid refers to the amount of Nicotine in that liquid.

The higher the rating, the stronger the throat hit, the more harsh the vape and the faster your craving is satisfied.

Some people will want a nice harsh taste to their liquids, so that they feel as small a difference between vaping and smoking.

These people choose a mid-high mg rated liquid, as it tastes better for them and helps to satisfy their cravings more quickly.

Others will be happy to continue with a nice fresh fruity liquid, with a low mg rating. They will enjoy the sensation of still exhaling something, which in turn satisfies their craving for Nicotine and yet is not detrimental to their health; like an old fashioned cigarette made of Tar and 4000 other chemicals.

There are even liquids produced with a ZERO mg rating for people who want to drop their vapouriser completely at some stage, and are successfully weening themselves off by using a 0mg liquid; but still getting all the visual triggers to help satisfy their cravings.

How do I know which mg rating I should choose?

The nicotine level you choose depends highly on your current or previous nicotine intake with cigarettes.

For an average 20 a day smoker, we recommend starting on 15mg as this will give the same level of nicotine and "throat hit" with each vape to keep you satisfied.

As you vape more and more, you may find yourself wanting to lower your nicotine intake and slowly make the change to 0mg E-Liquids.

However, if you are using a sub-ohm device, you will want to choose a lower nicotine strength. Most sub-ohm vapers tend to use anywhere between 3 and 6mg. This is because, on an average 3 second pull on a sub-ohm tank you are producing at least twice as much vapour as a regular tank. Continuing to use a high nicotine such as 15mg in a sub-ohm device will be incredibly harsh on the throat, may lead to a lot of coughing, and will almost certainly lead to a nicotine overload (note: not an overdose - it is almost impossible to overdose on nicotine with the levels found in E-Liquids, regardless of power or how much you vape) which may lead to headaches or nausea.
