1. A carrier unit for a nicotine carrier cartridge, the nicotine carrier unit comprising:
a carrier substrate, the carrier substrate comprising an aerosol-forming precursor comprising a nicotine-containing and/or flavoured fluid, gel, wax, or powder; and
a thermally conductive substrate, the thermally conductive substrate being formed into a cylinder that is configured to be pierced by a heater element of a device operative to initiate and maintain release of an aerosol from said carrier unit, such that penetration of the thermally conductive substrate by the heater element forms an aperture in the thermally conductive substrate;
wherein the thermally conductive substrate is configured to conduct heat from the heater element to the carrier substrate to cause indirect heating of the carrier substrate to a lower temperature than that experienced by the thermally conductive substrate, and thereby cause release of said aerosol-forming precursor from the carrier substrate.
