Knowra Electronic cigarette Electronic cigarette An electronic cigarette is a battery-powered device that heats a liquid into an inhalable aerosol, commonly containing nicotine and flavorings. It delivers aerosol without burning tobacco.
Atomizer : A component that converts liquid into fine droplets or aerosol, often by heating it. Its heating element vaporizes e-liquid for inhalation.
Nicotine dependence : A condition in which repeated nicotine use produces compulsive use and difficulty stopping. Nicotine-containing devices can sustain or create dependence.
Cigarette : A paper-wrapped roll of tobacco designed to be burned and inhaled. Combustion distinguishes cigarettes from devices that heat liquid.
Smoking cessation : The process of stopping the use of combustible tobacco products. Clinical research examines whether electronic cigarettes help smokers stop smoking.
Herbert A. Gilbert : An American inventor who patented a smokeless, non-tobacco cigarette concept in 1965. His patent described an early device that heated flavored air instead of burning tobacco.
E-liquid : A liquid formulated for electronic cigarettes, typically containing propylene glycol, vegetable glycerin, flavorings, and sometimes nicotine. Its ingredients determine the aerosol’s nicotine content, flavor, and physical properties.
Nicotine : A naturally occurring alkaloid found in tobacco that acts on nicotinic acetylcholine receptors. It is a common e-liquid ingredient and drives dependence.
Heated tobacco product : A device that heats processed tobacco to generate an inhalable aerosol without burning it. It heats tobacco rather than an e-liquid.
Tobacco control : Public-health policies and interventions intended to reduce tobacco use and its harms. Regulation addresses product safety, marketing, access, and exposure.
Hon Lik : A Chinese pharmacist credited with developing a modern electronic cigarette in the early 2000s. His design helped establish the liquid-based electronic cigarette that spread internationally.
