Introduction: In recent years, electronic cigarettes, also known as vapor cigarette, have emerged as a popular alternative to traditional tobacco cigarettes. This article aims to provide an in-depth understanding of what electronic cigarettes are, and how they differ from conventional smoking. Definition: An electronic cigarette is a handheld device that simulates the act of smoking by producing inhalable vapor. Unlike traditional cigarettes, which burn tobacco to generate smoke, electronic cigarettes operate on a vaporization principle. They are designed to deliver nicotine and other flavorings without the combustion process associated with traditional smoking. Electronic cigarettes offer several distinctions from traditional smoking: Electronic cigarettes offer several advantages over traditional smoking. Firstly, they eliminate the combustion process, resulting in reduced exposure to harmful chemicals and toxins present in cigarette smoke. Additionally, e-cigarettes provide users with the ability to control their nicotine intake by offering e-liquids in various nicotine strengths, including options with no nicotine at all. This allows individuals to gradually reduce their nicotine dependency if desired. Another benefit of electronic cigarettes is the absence of the strong lingering odor associated with tobacco smoke. The vapor produced by e-cigarettes tends to dissipate quickly and leaves behind minimal scent, making it a more discreet option for users and those around them. Furthermore, vape do not produce ash, making them more convenient and mess-free compared to traditional cigarettes.
