Combustion byproducts associated with ordinary smoking include carbon monoxide, which deactivates healthy red blood cells, and nitrogen oxides, which are potent irritants of the tissues of the throat and lungs. Dioxins also come from combustion, and so does benzo-a-pyrene, one of several thousand compounds known as polycyclic aromatic hydrocarbons, many of which have been linked with genetic mutation and cancer.

Lung-clogging particulate matter also comes from combustion. And toxic heavy metals such as cadmium, which some living plants take from the soil, get evaporated by the high temperatures of combustion and inhaled in ordinary tobacco smoking processes.

The low-temperature evaporation process used in the Flash Evaporator does not produce heavy-metal vapors or combustion byproducts because no combustion takes place -- in fact, plant material that has been depleted of its volatile constituents by the Flash Evaporator DOES NOT EVEN LOOK BURNED -- because it isn't burned!
