Claim 19:
20. An electronic vapor provision system comprising:
a control unit configured to provide power from a battery in the control unit to components of the electronic vapor provision system, and comprising a controller configured to control components of the electronic vapor provision system;
an aerosolizable substrate material carrying portion separably connectable to the control unit to obtain power from the battery, and comprising:
a first electrical circuit including a readable memory, and
a second electrical circuit including a vapor generating element configured to generate an inhalable vapor from an aerosolizable substrate material, wherein the second electrical circuit can be selectively provided with power from the battery when power is supplied to the aerosolizable substrate material carrying portion,
wherein the controller is configured to operate in a first mode in which property data indicating one or more properties of the aerosolizable substrate material carrying portion stored in the readable memory is determined by providing power from the battery to the first electrical circuit, and in a second mode in which the vapor generating element is operated by providing power from the battery to the second electrical circuit; and

a switching arrangement operable by the controller to selectively provide power from the battery to the second electrical circuit, wherein:
the switching arrangement is located in the aerosolizable substrate material carrying portion, and
the aerosolizable substrate material carrying portion comprises two electrical connection terminals for connection with the control unit, the electrical connection terminals comprising a first electrical connection terminal for providing power to the first electrical circuit and the second electrical circuit, and an electrical earth connection for the first electrical circuit and the second electrical circuit, and the switching arrangement is configured to switch between connecting the first electrical circuit with the first electrical connection terminal and connecting the second electrical circuit with the first electrical connection terminal.
