ABSTRACT:
A drug delivery article provides a dose of a volatilized drug by heating a drug carrying substrate, but not burning any 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 the drug in a heat exchange relationship therewith. The drug volatilizes and is drawn into the mouth of the user of the article. Typical heat sources heat the drug to a temperature within 70.degree. C. to 200.degree. C. for 4 to 8 minutes.
