Electronic cigarettes, also known as e-cigs, vape pens and mods, are battery-operated devices used to inhale--or “vape”--an aerosol, which typically contains nicotine, flavorings and other harmful chemicals.  Many may have heard the term “Juul,” a brand-name e-cigarette, or the term “juuling,” which is another word for vaping.
