1. Smoking article, comprising:
a mouthpiece for drawing in a heated particle-loaded gas,
at least one cooling element for cooling the particle-loaded gas, the at least one cooling element being arranged at a location such that the particle-loaded gas will flow through the cooling element during a drawing-in action,
wherein the at least one cooling element has a cooling material that is able to produce said cooling by the cooling element by an endothermic process of the cooling material activated by the heated particle-loaded gas,
wherein the cooling element comprises an elongate carrier material with the cooling material, and
wherein the cooling material has been pressed or brushed onto the surface of the elongate carrier material.
