Abstract: The disclosure provides liquid aerosol precursor compositions adapted for use in an aerosol delivery device, comprising two or more organic acids. For example, one such composition includes: at least one aerosol former, nicotine, benzoic acid, lactic acid, and levulinic acid, wherein benzoic acid is present in a molar ratio of benzoic acid to nicotine of at least 0.15, wherein lactic acid is present in a molar ratio of lactic acid to nicotine of at least 0.2, and wherein levulinic acid is present in a molar ratio of levulinic acid to nicotine of at least 0.12. The disclosure further provides devices and kits incorporating such compositions.

Abstract: The present disclosure provides a control body, an aerosol delivery device, and a method of operating an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control body having a housing, an electrical energy source located within the housing, a heating member operatively connected to the electrical energy source, an aerosol source member that includes an inhalable substance medium, and an indexing mechanism coupled to the heating member. The indexing mechanism is configured to move the heating member relative to the aerosol source member so as to sequentially heat one of two or more segments of the aerosol source member.
