e-cigarette oil is also called e-cigarette liquid. It is an electronic atomizing liquid used with electronic cigarettes. Heated by an electronic cigarette atomizer, it can produce fog like cigarettes. The main components of e-cigarette oil are food-grade or medical-grade glycerol, propylene glycol and polyethylene glycol, as well as special tobacco essence. E-cigarette oil also contains nicotine, and nicotine is added mainly to make it taste closer to cigarettes.

E-cigarette oil is used in conjunction with e-cigarettes, generally ranging from 1.5 ml to 1 ml at a time. Use a pointed-nosed bottle, drop the cigarette oil into the atomizer and shake well. When using, pay attention to the amount of smoke oil in the atomizer. Too little smoke oil will cause damage and smell of the atomizer.
