A heat source which includes granular magnesium, granular iron, and finely divided cellulose generates heat upon contact thereof with an aqueous solution of potassium chloride. The heat source is in a heat exchange relationship with the flavor or drug. Heat generated by the heat source heats the flavor or drug in a controlled manner. The flavor or drug volatilizes and is drawn into the mouth of the user of the article. Typical heat sources heat the flavor or drug to a temperature within about 70° C. to about 180° C. for 4 to 8 minutes. | |
