A method of authenticating a consumable for use with an aerosol generating device, includes initiating a communication between the aerosol generating device and a first entity to obtain the consumable from the first entity for use with the aerosol generating device, the aerosol generating device being associated with a device ID and the consumable being associated with a consumable ID; sending the device ID and the consumable ID from the first entity to a second entity, wherein the second entity is configured to associate and store the device ID with the consumable ID; and verifying use of the consumable with the aerosol generating device.

An aerosol provision system for generating aerosol from an aerosol-generating material. The system comprises an article comprising the aerosol-generating material and an aerosol provision device configured to engage with the article and to enable generation of aerosol from the aerosol-generating material. The system further includes detection circuitry for detecting when the article is engaged and/or disengaged with the aerosol provision device, and control circuitry for controlling operation of the aerosol provision device. The control circuitry is configured to switch the aerosol provision device from a first operating mode to a second operating mode when the control circuitry determines the article has been engaged with and/or disengaged with the aerosol provision device a plurality of times. By requiring both that the user must engage and/or disengage the article and the device, and that the user must do so a plurality of times, further reduces the chances of the user inadvertently switching to the second operating mode. Also disclosed is an aerosol provision device and a method for switching from the first operating mode to the second operating mode.

An aerosol generation system for generation of an aerosol from an aerosol-forming precursor includes an electrically operated heating system to heat the precursor to generate the aerosol, a flow path for transmission of flow, including the aerosol, to a user, the heating system arranged in fluid communication with the flow path, and electrical circuitry. The electrical circuitry is configured to apply a predetermined amount of electrical energy to the heating system to stabilise a property of electrical energy through the heating system, and determine a property related to the flow of the flow path based on the stabilised property of the electrical energy through the heating system, wherein the property related to the flow is an amount of one or more components of the aerosol.

A sensing module for monitoring dosage delivery of a vaporized material, and a portable vaporization unit including the sensing module, include a light sensor that detects disruptions in a light path across a vapor channel, the disruptions caused by the vaporized material flowing through the vapor channel. The light sensor includes a UV light source, which may emit 370 nm wavelength light, and a UV light detector that converts intensity of incident light in the light path into a signal. A microprocessor of the sensing module compares the signal to a baseline measurement to determine the concentration of a medicament in the vapor; then, using the flow rate and activation time of the device, the microprocessor determines the dosage and can perform monitoring and reporting actions based on the dosage. A measuring circuit measures fluctuations in resistance/impedance of a vaporization element to further determine flow rate and/or dosage.
