What is vaping?

Vaping is the act of inhaling vapor produced by any kind of e-cigarette or personal vaporizer. E-cigarettes are portable battery-powered devices that heat a coil housed in an atomizer that transforms “e-liquid” into vapor. The e-liquid is a mixture of propylene glycol - a synthetic organic compound with the chemical formula C₃H₈O₂. It is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet taste, vegetable glycerine - a clear, odorless liquid, used in food applications is USP grade or over 99% pure and has a sweet taste, and usually with water-soluble food flavorings. Nicotine is optional and customizable.
