Smoking article for on-demand delivery of an increased quantity of an aerosol precursor composition, a cartridge, and a related method

A smoking article, comprising:

• a control body;
• and
• a cartridge engaged with the control body, the cartridge comprising:
• a housing having a proximal end and an opposing distal end engagable with the control body;
• a reservoir disposed within the housing and extending longitudinally from a first end disposed toward the proximal end of the housing to a second end disposed toward the distal end of the housing, the reservoir defining two or more chambers each having an aerosol precursor composition disposed therein, and being in fluid communication with an aerosol forming arrangement configured to form an aerosol from any of the aerosol precursor compositions, the respective aerosol precursor compositions of the two or more chambers being directed to the aerosol forming arrangement in substantially equal normal quantities;
• and
• an actuator engaged with the housing and configured to selectively and operably engage any one of the two or more chambers defined by the reservoir, the actuator, upon actuation thereof, being configured to direct an increased quantity of the aerosol precursor composition from the chamber engaged therewith to the aerosol forming arrangement, the increased quantity being greater than the normal quantity of the aerosol precursor composition.
