Abstract
Abstract A substantial amount of tar, nicotine, and some other hydrocarbons in the smoke of a cigarette could be condensed on a metallic surface, if that metallic surface is properly positioned inside that cigarette. The metallic surface in this disclosure may be porous pellets of aluminum foil which may be scattered amid the tobacco of the cigarette, or they may be axially arranged as a column in the cigarette. Also, using these porous pellets of aluminum foil in a cigarette can find a use in medicine, as they may be filled with a dosage of a medicament.
