An electronic hookah works like an electronic cigarette kit, so you can vape all your favourite e-liquids. Whether they contain nicotine or not, you can enjoy the capabilities of your e-hookah. However, since it's designed for direct inhalation with relatively high power, the coils will not be suitable for e-liquids with nicotine salts. Nicotine salt liquids are meant to be vaped at relatively low power. We also recommend using e-liquids with more than 50% vegetable glycerine.
