It involves the use of a battery-powered device that heats a liquid solution (known as e-liquid or vape juice) containing nicotine, flavorings, and other chemicals. The liquid is heated to produce a vapor that is then inhaled, simulating the experience of smoking a traditional cigarette. Vaping devices come in many forms, including pens, mods, and pods, and can range from simple and inexpensive to complex and expensive. Some people view vaping as a safer alternative to smoking cigarettes, while others are concerned about the potential health risks associated with inhaling chemicals and nicotine. The long-term effects of vaping are still being studied, but it's generally accepted that it's less harmful than traditional smoking.
