Thermal vaporizing device for drug delivery

A method of delivering a drug to the lungs of a user, the method comprising the steps of

• providing a drug delivery device comprising a plurality of inert inorganic particles, the particles having the drug adsorbed thereon, means for heating the plurality of inert inorganic particles to cause the drug to volatilize and become desorbed from the plurality of inert inorganic particles, and means for directing the volatilized and desorbed drug into the lungs of the user,
• heating the plurality of inert inorganic particles to cause the drug to volatilize and become desorbed from the plurality of inert inorganic particles, and
• directing the volatilized and desorbed drug into the lungs of the user.

A method of delivering a drug to the lungs of a user, the method comprising the steps of

• providing a drug delivery device comprising a tubular housing having a proximal end section comprising a mouthpiece, a distal end section comprising a heat source that can be selectively activated, and a middle section between the proximal end section and the distal end section, the middle section having an chamber containing a plurality of inert inorganic particles, the particles having the drug adsorbed as a coating thereon, wherein the heat source of the distal end section, the plurality of inert inorganic particles in the middle section and the mouthpiece of the proximal end section are fluidly connected through an interior passageway of the tubular housing and wherein the distal end section is fluidly connected to outside air and wherein the proximal end section can be connected to the mouth of a user so that air can be drawn into the heat source by suction applied by the user and heated and wherein the heated air can be drawn into the chamber of the middle section to heat, volatilize and desorb the drug from the inert particles and wherein the volatilized and desorbed drug can be drawn from the chamber of the middle section into the mouthpiece and then into the mouth and lungs of the user,
• activating the heat source, and
• allowing the user to apply suction to the mouthpiece.
