E-cigarettes are battery-powered devices that are considered less toxic than traditional cigarettes. Also known as e-cigs, e-vaping devices, vape pens and electronic cigarettes, these cigarettes consist of three main components, namely, a heating coil, battery and an e-liquid cartridge. These components help in delivering dosages of vaporized nicotine or flavored solutions to the users. E-cigarettes are gaining popularity, especially among young adults and adolescents, due to the rising awareness about the harmful effects of traditional tobacco-based cigarettes. However, researchers are still assessing the impact of e-cigarettes on the human body, which is not yet known.
