Vaping technology has evolved significantly from early e-cigarette designs to modern devices like box mods and pod systems. Vapers now have many options to customize their vaping experience, including different atomizers, voltage and wattage settings, drip tips, and a huge selection of e-liquid flavors. E-liquids contain propylene glycol or vegetable glycerin as a base along with flavorings and sometimes nicotine. Propylene glycol produces more of a throat hit than vegetable glycerin but creates less vapor. Overall, vaping devices and e-liquids now come in a diverse range of options to suit different users.
