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. ## Claims ### Claim 1 An additive assembly for an electronic vaping device (EVD), the additive assembly comprising: an adsorbent material including adsorbed carbon dioxide, the adsorbent material configured to release the carbon dioxide into a vapor based on at least a portion of the vapor adsorbing on the adsorbent material, the adsorbent material further configured to generate heat based on the portion of the vapor adsorbing on the adsorbent material. ### Claim 2 (depends on 1) The additive assembly of claim 1, further comprising: a flavor material including a flavorant, the flavor material configured to release the flavorant into the vapor based at least in part on absorbing the heat generated by the adsorbent material. ### Claim 3 (depends on 2) The additive assembly of claim 2, wherein the flavor material includes a plurality of beads, and each of the beads includes the flavorant. ### Claim 4 (depends on 2) The additive assembly of claim 2, wherein the flavor material includes at least one botanical substance, and the at least one botanical substance includes the flavorant. ### Claim 5 (depends on 2) The additive assembly of claim 2, wherein the additive assembly includes at least first and second additive structures, the first and second additive structures include at least one material of the adsorbent material and the flavor material, and the first and second additive structures at least partially define a boundary of at least one flow pathway between the first and second additive structures. ### Claim 6 (depends on 1) The additive assembly of claim 1, wherein the adsorbent material is a plurality of adsorbent beads. ### Claim 7 (depends on 1) The additive assembly of claim 1, wherein the adsorbent material includes at least one of zeolite, silica, activated carbon, and molecular sieves. ### Claim 8 An additive assembly for an electronic vaping device (EVD), the additive assembly comprising: a plurality of additive structures at least partially defining a boundary of at least one flow pathway between the plurality of additive structures, each additive structure of the plurality of additive structures including at least one material of an adsorbent material including adsorbed carbon dioxide and a flavor material, wherein the adsorbent material is configured to release carbon dioxide into a vapor based on at least a portion of the vapor adsorbing on the adsorbent material, and generate heat based on the portion of the vapor adsorbing on the adsorbent material, wherein the flavor material includes a flavorant, the flavor material configured to release the flavorant into the vapor based at least in part on absorbing the heat generated by the adsorbent material. ### Claim 9 (depends on 8) The additive assembly of claim 8, wherein the plurality of additive structures collectively at least partially define a plurality of flow pathways, the plurality of flow pathways having different orientations, such that the plurality of additive structures are configured to direct a vapor flowing through the plurality of flow pathways to change direction based on flowing through differently-oriented flow pathways. ### Claim 10 (depends on 9) The additive assembly of claim 9, wherein the plurality of additive structures are configured to direct the vapor flowing through the plurality of flow pathways to change direction based on flowing through differently-oriented flow pathways. ### Claim 11 (depends on 10) The additive assembly of claim 10, wherein at least one flow pathway of the plurality of flow pathways is configured to direct the vapor flowing through the plurality of flow pathways to impinge on an outer surface of at least one additive structure of the plurality of additive structures. ### Claim 12 (depends on 1) An e-vaping device, comprising: a vaporizer assembly configured to form a generated vapor;
