E-liquid, or vape juice, is the liquid that is used in an e-cigarette. The e-cigarette is a battery-powered device that heats the liquid into an aerosol that is then inhaled into the lungs. E-liquid arrives with a tremendous scope of flavour choices and qualities, so you have not stayed with only tobacco. There will always be novel e-liquids and unique blends to try! While vapers disagree about whether PG or VG should be used in e-liquid, the benefits of both can be seen here. Nicotine, propylene glycol, vegetable glycerin, glycerol, and other chemicals (including those used to make flavours) can all be present in e-liquids. In some cases, water is also present.
