1. A cigarette which does not burn tobacco comprising:
- (a) tobacco; and
(b) a physically separate, non-combustion heat source for heating but not burning the tobacco, and including(i) a first chemical agent capable of interacting exothermically with a second chemical agent, and a third chemical agent capable of interacting exothermically with the first chemical agent, and(ii) a dispersing agent for the first agent.

Abstract
A cigarette provides tobacco flavor by heating tobacco, but not burning tobacco or any other material. A heat source which includes a metal oxide (e.g., calcium oxide), an anhydrous metal sulfate (e.g., 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° C. to 200° C. for 4 to 8 minutes.
