Electronic cigarette is usually made up of the smoke tube which is used for putting nicotine liquid, evaporator and battery, and the nicotine liquid will be evaporated by heat and be absorbed into mouth while using electronic cigarette since nicotine is usually soluble in propylene glycol liquid, making smokers can exhale white mist while using electronic cigarette.
