1. An aerosol generating system comprising:
an aerosolizable material, wherein the aerosolizable material comprises at least two sections, wherein at least one of the at least two sections comprises a tobacco material and wherein the at least two sections of the aerosolizable material have different compositions; and
at least a first heater and a second heater, wherein the first heater and the second heater are arranged to respectively heat the at least two sections of the aerosolizable material,
wherein the aerosol generating system is configured such that during a session of use by a user, after initiation of heating of a first of the at least two sections by the first heater, the second heater is selectively actuatable by the user to heat a second of the at least two sections to a temperature which causes volatilization of aerosolizable components of the second section, and
wherein the system comprises a user input mechanism, wherein the user input mechanism is operably by the user in use to cause actuation of the second heater to provide user control over the volatilization of the components of the second section to facilitate user control over the composition of a generated aerosol.
