Vape juice, also known as e-liquid or e-juice, is the liquid used in vape devices that creates the vapor vapers inhale. It primarily consists of a combination of propylene glycol (PG) and vegetable glycerin (VG), which serve as the base liquids. These bases carry flavorings and often contain nicotine, although nicotine strength can vary or be absent. Propylene glycol (PG) is a clear, scentless liquid that carries flavor well and produces a stronger throat hit, similar to traditional cigarette smoke. Vegetable glycerin (VG) is a thicker, sweeter liquid that produces denser vapor clouds and provides a smoother throat hit. Vape juice may have different ratios of PG to VG to affect the vaping experience, such as flavor intensity, vapor production, and throat sensation. Besides these bases, vape juice includes flavorings ranging from tobacco and menthol to fruit and dessert flavors. Nicotine is an optional ingredient often added in concentrations tailored to the user's preference. The liquid is specifically formulated to be safely vaporized and inhaled through a vaping device. In summary, vape juice is a specially formulated liquid made mainly of PG, VG, flavorings, and optionally nicotine, designed to produce vapor and deliver flavor and nicotine when heated in a vape device.
