The eliquid industry is huge and with a healthy variety of flavors, strengths, and ratios it can be overwhelming for new vapers. However, all liquids sold in the UK must go through some of the world’s strictest safety testing to be approved for sale, and thankfully the vast majority do not contain any harmful chemicals at all.
The liquids used in e-cigarette cartridges, vape pens and cig-alikes (also known as JUULs) heat up to create the nicotine vapor that is inhaled by the user. The vapor is odorless, does not produce any tar or 2nd hand smoke, and can be enjoyed in many places where cigarette smoking has been banned.
Almost all liquids contain propylene glycol and vegetable glycerine, along with flavorings and optionally, nicotine. The two primary ingredients are then mixed in a ratio that affects the performance and cloud production of the liquid, as well as the overall vaping experience.

Nicotine is added to e-liquid in the form of nic salts or synthetic nicotine and can be found in a range of strength options to suit any vaper. The type of nicotine added also affects the vaping experience, with synthetic nic shots being milder in comparison to nic salts.
A high VG liquid will generally produce thicker clouds than a low PG one, as the more viscous ingredient produces more vapor. A 50/50 e-liquid is a good choice for beginners as it allows you to switch between PG and VG vaping styles, whilst a VG-only liquid will typically provide a smooth throat hit with little to no cloud production.
