Disclosed is a method and device for rapid heating of a coated substance which preferably includes a drug to vaporize for inhalation therapy. A device (10) in accordance with the present invention preferably includes a substrate (20) which has an interior surface (20a) surrounding an interior region and an exterior surface (20b) upon which the coated substance (15) is to be adhered. Though the substrate is preferably metallic, it does not need to be. A combustible element (16a.16b) is placed in the interior region of the substrate and a spark or resistance igniter is connected to the combustible element. The igniter is for initiating oxidation of the combustible element. Preferably, the coated substance is vaporized inside of a housing (30) to allow the vaporized drug to aerosolize and be inhaled by a user.
