A system comprising an aerosol provision system and a computer. The aerosol provision system is configured to generate aerosol from an aerosol-generating material. The computer is configured to obtain user behaviour data relating to an amount of an ingredient delivered from the aerosol-generating material to a user of the aerosol provision system. The computer then determines default user behaviour with respect to the amount of the ingredient to be delivered on the basis of the obtained user behaviour data. The computer then identifies, based on the obtained user behaviour, under what conditions to deliver a notification to the user, the notification informing the user of the user's current behaviour. |
