There is no difference between e-juice and e-liquid. They’re simply two terms used to describe the same product. E-liquid was the original term many product manufacturers used to describe their vape liquid, while e-juice became the more popular way to describe vape liquid by the vaping community. In recent years, vape juice has replaced both terms as the most common way to describe vape liquid. So when you see or hear any of the three terms: e-liquid, e-juice or vape juice, know that they’re describing the same thing.
