Abstract

A drug delivery device for delivery of a drug to the lungs of a user includes a tubular housing having a mouth a mouthpiece, a heat source, and a middle section between the mouthpiece and the heat source. The middle section has an chamber containing a plurality of inert inorganic particles which have a drug adsorbed as a coating thereon. The heat source, the plurality of inert inorganic particles in the middle section and the mouthpiece are fluidly connected through an interior passageway of the tubular housing and the distal end section is fluidly connected to outside air. When a user applies suction to the mouthpiece, air from the outside is drawn into the heat source by suction and is heated, and the heated air is drawn into the chamber of the middle section to heat, volatilize and desorb the drug from the inert particles. The volatilized and desorbed drug is then drawn from the chamber of the middle section into the mouthpiece and then into the mouth and lungs of the user.
