A cigarette (10) provides tobacco flavor by heating tobacco (16), but not burning tobacco or any other material. A heat source (35) which includes a metal oxide (eg., calcium oxide), an anhydrous metal sulfate (eg., magnesium sulfate), an inorganic salt and a sugar, generates heat upon contact of water therewith. The heat produced by the heat source heats tobacco in a heat exchange relationship therewith. Flavors volatilize from the tobacco and are drawn into the mouth of the user of the cigarette. Typical heat sources heat the tobacco to a temperature within 70 DEG C to 200 DEG C for 4 to 8 minutes. |
