Abstract
An additive assembly for an e-vaping device includes an adsorbent material that includes adsorbed carbon dioxide. The additive assembly may be in fluid communication with a vaporizer assembly that forms a generated vapor. The adsorbent material may release the carbon dioxide into the generated vapor based on at least a portion of the generated vapor adsorbing on the adsorbent material. The additive assembly may include a flavor material including a flavorant. The adsorbent material may generate heat based on at least a portion of the generated vapor adsorbing on the adsorbent material, and the flavor material may release flavorant into the generated vapor based at least in part on the heat generated by the adsorbent material. One or more of the adsorbent material and the flavor material may be included in beads. Adsorbent material and flavor material may be included in multiple additive structures within the additive assembly.
