    摘要： A smoking article for on-demand delivery of an increased quantity of an aerosol precursor composition, a cartridge, and a method are disclosed. In some aspects, the cartridge (300) includes a housing, and a reservoir (316) disposed within the housing and defining two or more chambers (318A-C) each having an aerosol precursor composition therein. The reservoir is in fluid communication with an aerosol forming arrangement (308) configured to form an aerosol from any of the aerosol precursor compositions, with the respective aerosol precursor compositions of the two or more chambers being directed to the aerosol forming arrangement in substantially equal normal quantities. The cartridge further includes an actuator (328) configured to selectively and operably engage any one of the chambers and 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 compositions.
