If you have recently switched to vaping or thinking of joining the League of vapers, you must have come across the term ‘e-liquid’. But what is e-liquid? You remain confused about it as a newcomer. E-liquid is often known as vape juice. It is a substance which is used in vape kits and e-cigarettes for producing vapour. E-liquids are available in multiple flavours, nicotine strengths and formulations. E-liquid can upgrade your vaping experience. In this blog, we will explore for our readers all they need to know about e-liquids in 2025 such as what are its different types and ingredients.

What Is E-Liquid and How Does It Work?

E-liquid contains four major components such as propylene glycol (PG), Vegetable Glycerine (VG), flavouring and nicotine (which is optional). When the vape device is activated, the e-liquid gets heated by a coil and it turns into vapour which is then inhaled by the user.

The flavour is carried by PG, and it gives its users satisfying throat hits while thicker clouds are produced by VG. By adjusting the PG/VG ratios, the manufacturers of vapes cater to different preferences of users.

Types of E-Liquids Available in the UK

E-liquids are available in multiple forms to cater to the different needs of users and different devices. These include:

• Freebase Nicotine E-liquids: which are traditional and widely available
• Nic Salts: give a smoother throat hit and faster absorption of nicotine making it an ideal choice for heavy smokers who are looking to transition from smoking to vaping
•  Shortfills: are larger bottles that come with zero nicotine, they are designed to be mixed with nicotine shots.

For heavy smokers who want to adapt to a better lifestyle and smoking habit, Nic Salts offers them a satisfying alternative that gives quick nicotine delivery without being harsh on the throat.
