Not to be confused with humidifier.
For the device used in surgery, see anaesthetic vaporiser.
A vaporizer (or vapouriser) is a device used to sublimate the active ingredients of plant material, commonly cannabis, tobacco, or any of many other therapeutic or medicinal herbs or blends (phyto-inhalation; see also: aromatherapy). Vaporization is an alternative to smoking. Rather than burning the herb, which produces irritating, toxic, and carcinogenic by-products, a vaporizer heats the material in a partial vacuum so that the active compounds contained in the plant boil off into a vapor. No combustion is evident. Therefore no smoke or taste of smoke is evident. The vapor ideally contains virtually zero particulate matter or tar, and significantly lower concentrations of noxious gases such as carbon monoxide. The vapor is then inhaled directly through a hose or pipe for highest activity, or stored for subsequent inhalations in a container such as a bag or jar. With little to no smoke produced, cooler temperatures, and less material required to achieve a given level of effect, the irritating/harmful effects of smoking are greatly reduced or eliminated,[1][2][3][4][5] along with second hand smoke, by using a vaporizer. This makes vaporizers useful in places where there are public bans on smoking and under circumstances in which a more medically justifiable delivery medium is preferred.
