Vape juices, also known as e-liquids, are liquids used in electronic cigarettes and vaporizers. They typically contain a mixture of propylene glycol, vegetable glycerin, flavorings, and sometimes nicotine. The liquid is heated to create vapor, which users inhale. Vape juices come in various flavors, ranging from fruity to dessert-like options, catering to different preferences. The nicotine content can vary, allowing users to choose their desired strength or opt for nicotine-free options. This versatility has contributed to the popularity of vaping as an alternative to traditional smoking.
