1. A cartridge device comprising:
a cartridge body extending in a distal to proximal axis and having a width and a diameter that are transverse to the distal to proximal axis, the cartridge body further having a proximal body end and a distal body end opposite the proximal body end along the distal to proximal axis;
a reservoir formed within the cartridge body, the reservoir configured to contain a vaporizable material;
a back piece forming a distal reservoir end of the reservoir and being sealed to the cartridge body from within the cartridge body;
a mouthpiece at the proximal body end of the cartridge body;
a bottom cover plate forming a distal end of the cartridge device, the bottom cover plate opposite the mouthpiece, the bottom cover plate comprising an external surface of the cartridge device, wherein an air chamber is formed between the back piece and the bottom cover plate;
an air flow path extending between the air chamber and the mouthpiece, the air flow path extending through the reservoir;
a heater within the air flow path;
a pair of electrical contacts in electrical communication with the heater; and
one or more air openings on the external surface of the cartridge device, wherein the one or more air openings are fluidly connected with the air flow path.
