Vaping is the act of inhaling and exhaling vapor produced by an electronic cigarette or similar device. Vaping devices heat a liquid, often containing nicotine and other chemicals, to create an aerosol that is then inhaled into the lungs. Vaping has become increasingly popular in recent years, particularly among young people, and there is ongoing debate about its safety and potential health risks. Some studies suggest that vaping may be less harmful than smoking traditional cigarettes, but there are also concerns about the long-term effects of exposure to the chemicals and metals found in vaping liquids and devices.
