What is the difference between different types of e-juice?

E-juice is a liquid intended for compatible refillable e-cigarettes. The product is also called vape juice, e-liquid or e‑liquid. It typically consists of propylene glycol (PG), vegetable glycerin (VG) and flavorings. Depending on the product it may contain nicotine or be nicotine‑free.

The product's nicotine content is stated on the product page and packaging, usually in milligrams per milliliter, mg/ml. A product listed as 0 mg/ml is nicotine-free. Always check the current product information as nicotine content and nicotine type vary between different e-juices.

VG stands for vegetable glycerin and PG for propylene glycol. The ratio is usually given as, for example, 50/50 or 70/30 and affects, among other things, the liquid's viscosity. Which VG/PG ratio is compatible depends on the e-cigarette's construction, pod, tank and coil.

No. Compatibility depends among other things on the device’s construction, coil resistance, recommended power range and the e‑juice’s VG/PG ratio. Check the information for both the e‑juice and the specific e‑cigarette. Read more in the guide Can you use any e‑juice in your vape?.
