E-liquids, also known as vape juice, are the essential liquids used in electronic cigarettes and vaping devices. Comprising a blend of propylene glycol (PG), vegetable glycerin (VG), flavorings, and sometimes nicotine, e-liquids come in a vast array of flavors and nicotine strengths. Users can choose from fruity, dessert, menthol, or tobacco flavors to suit their preferences. The liquid is vaporized by a heating element in the device, creating the inhalable vapor that users enjoy. E-liquids offer vapers a diverse and customizable experience, allowing them to explore different flavors and nicotine levels.
