What exactly is in an e cigarette?

With the media giving mixed messages about e cigarettes it’s easy to see why people would be confused. Are they good, are they bad, do they smell, can people be harmed by breathing the vapour in second-hand? No, no and no! Sometimes the information surrounding e cigarettes isn’t clear and not everybody knows what’s involved.

cheap e liquid

An e cig is used as an alternative to smoking or as a way to help quit smoking altogether. They are electronic vaporizers and are usually made up of a battery, an atomiser or heating element as well as a cartridge for e liquid. But what is an e liquid made of? People are often curious and it’s always helpful to know the components of a product you are using:

Water

Water is used as one of the main substances; it holds all the other ingredients together and helps vaporisation of the e liquid.

Propylene Glycol (PG)

Propylene Gycol is used in many products that we use every day, from cosmetics to food and e cigs. It’s a substance that absorbs water and has no taste, odour or colour and is completely safe.

Vegetable Glycerin or glycerol


This is a thick liquid that is too thick to be used as vapour smoke on its own, and it is made from plants. It’s often used as a sweetener in foods and cosmetics.

All of these ingredients together make up an e liquid, and the only other two ingredients added are nicotine and flavouring. The nicotine comes in different strengths, more commonly in 6mg, 12mg, 18mg and 24mg measures depending on how much you need it. If you’re trying to quit, going from a normal cigarette to 24mg is a good start and then slowly decreasing the measure until you get an e liquid without nicotine!
