Vaping
Introduction
Vaping refers to inhaling vapor (volatilized liquid) produced by battery-powered devices. The vapor can containnicotine, tetrahydrocannabinol (THC) and cannabinoid (CBD) oils, and other substances, flavorings, and additives. Although the liquid ingredients are volatilized by heating, there is no combustion involved; the apparent "smoke" that results is water vapor.
