Electronic hookahs offer the fun and relaxation of a standard hookah, but without the need for charcoal, open flame, or any of the accoutrements needed for a hookah. These small devices, roughly the size of a pen, are great for portable use. As the only byproduct is typically water vapor, they are legal in many workplaces and create no secondhand smoke dangers.
Typically, electronic hookahs (e-hookahs) contain a flavored liquid heated by an atomizer, producing water vapor that can be inhaled like smoke. Some e-hookahs contain nicotine, a variety popular for those looking to quit smoking cigarettes. E-hookahs can be used to smoke vapors of a wide variety of flavors, just like a standard hookah, and are viewed by most as a safe alternative to cigarettes.
