An electronic cigarette, commonly known as an e-cigarette or vape, is a battery-operated device that heats a liquid solution, converting it into vapor for inhalation. This vapor typically contains nicotine, flavorings, and other additives. E-cigarettes offer an alternative to traditional tobacco smoking, eliminating the combustion process and reducing exposure to harmful chemicals present in conventional cigarettes. They come in various styles and flavors, catering to diverse preferences. While some view e-cigarettes as a potentially less harmful option for adult smokers, debates persist about their long-term health effects and appeal to youth.
