A Volcano forced-air Vaporizer. After filling, the balloon (top) may be unfastened and inhaled from.A vaporizer (or vapouriser) is a device used to extract and deliver via inhalation the active ingredients of plant material, commonly cannabis, tobacco, or any of many other 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 occurs, so 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. Also, less chance of flames occur. The vapor is extracted in various forms of extraction chambers then inhaled directly through a hose or pipe including vapor-specific vaporization water tools 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.
In comparison to other drug delivery methods such as ingestion, vaporization offers the advantages of rapid onset of pharmacological effect, direct delivery into the bloodstream (via the lungs), and more precise titration such that the desired level is reached and not exceeded, enabling consistent and appropriate dosage.
