Aerosol provision system

A method of accessing a chamber for aerosol precursor material comprised in an aerosol provision cartridge for an aerosol provision system, wherein the aerosol provision cartridge comprises the chamber for aerosol precursor material, the chamber comprising a first opening and a second opening each allowing for access into the chamber, wherein each opening is covered by a respective cap which is configured to be uncoupled from the chamber for allowing access to the opening, wherein the aerosol provision cartridge is configured such that each cap, when coupled to the chamber, requires at least two different actions to be uncoupled from the chamber;

• wherein the cartridge further comprises an aerosol generating component located in the chamber;
• wherein the cap for the first opening includes an orifice through which the aerosol generating component projects when the cap for the first opening is coupled to the chamber;
• wherein the aerosol provision cartridge further comprises a retaining means configured to hold the aerosol generating component inside the chamber when the cap for the first opening has been uncoupled from the chamber, and
• wherein the method comprises the steps of:
• performing a first action on one of the caps;
• and
• performing a second action on the cap;
• wherein the first action is different to the second action.
