1. A smoking article comprising:a cartridge body having a mouth end and an engaging end opposite the mouth end, the cartridge body including therein:
storage for an inhalable substance;
a resistive heating element; and
a first electrical contact coupled with the resistive heating element; and
a control housing having a receiving chamber with an open end defined by a wall with an inner surface and an outer surface, the control housing including:
a power source;
a puff-actuated sensor; and
a second electrical contact electrically coupled with the power source;
wherein the receiving chamber is configured to receive the engaging end of the cartridge such that the first electrical contact makes an electrical connection with the second electrical contact and electrical current can be provided from the power source to the resistive heating element so as to heat the inhalable substance to form an aerosol in response to the puff-actuated sensor sensing draw on the mouth end by a user of the smoking article;
wherein the control housing is configured for allowing entry of ambient air into the receiving chamber for passage into the cartridge body;
wherein the wall of the receiving chamber of the control housing comprises at least one opening therein; and
