A piece of technology that mimics smoking tobacco. It is made of an atomizer, a battery or other form of power source, and a cartridge or other type of container. The person using it breathes in vapor, not smoke.

Using an e-cigarette is frequently referred to as “vaping”. The atomizer is a heating component that evaporates an e-liquid solution into a fine mist of vapor and air that soon cools.

E-cigarettes can be started by inhaling or by pushing a button. Some of them resemble conventional cigarettes, and the majority of them are reusable.
