There is provided a cartridge (70) for an electronic vaping device (60), the cartridge (70) comprising a vaporizer assembly (22) configured to form a generated vapor and an additive assembly (24) in fluid communication with the vaporizer assembly (22). The additive assembly (24) includes an adsorbent material including adsorbed carbon dioxide, the adsorbent material configured to release the carbon dioxide into the generated vapor based on at least a portion of the generated vapor adsorbing on the adsorbent material, the adsorbent material further configured to generate heat based on at leasta portion of the generated vapor adsorbing on the adsorbent material.
