Vaporizers A vaporizer is a device used to extract for inhalation the active ingredients of plant material, commonly cannabis, tobacco or other herbs or blends. Vaporization is an alternative to burning smoking which avoids the production of irritating, toxic, and carcinogenic by-products by heating the material so its active compounds boil off into a vapor. No combustion occurs, so no smoke or taste of smoke is present. Vapor ideally contains virtually zero particulate matter or tar, and significantly lower concentrations of noxious gases such as carbon monoxide. With little to no smoke produced and cooler temperatures, less material is required to achieve a given level of effect. Hence, the irritating and harmful effects of smoking are greatly reduced or eliminated. Table of vaporization temperatures
