E-Liquids, also referred to as vape juice or e-juice are the liquids that are placed inside the tank of an e-cigarette device in order to create a vapour. It is used in all electronic cigarettes. When heated and inhaled, this provides a similar experience a smoker may experience when they smoke a cigarette, however nothing is actually burned. This means that none of the toxins and harmful substances consumed when smoking a cigarette will be consumed. The liquid creates a vapour when heated that is inhaled and exhaled. E-liquid is made up by 4 key components; propylene glycol (PG), vegetable glycerine (VG), nicotine and food-grade flavouring. There are thousands of different e-liquid flavourings for you to choose from, the majority of which are nicotine free, and are nic-shot ready (there is space left in the bottle for nicotine to be added), referred to as shortfills.
