Abstract: An aerosol provision cartridge (30) for an aerosol provision system (10). The cartridge (30) comprises a refillable chamber (100) for aerosol precursor material, the chamber (100) comprising a first opening (102) and a second opening (104), each opening (102;104) allowing for access into the chamber (100). Each opening (102;104) is covered by a respective cap (130;132) which is configured to be uncoupled from the chamber (100) for allowing access to the opening (102;104). The cartridge (30) is configured such that each cap (130;132), when coupled to the chamber (100), requires at least two different actions (A1;A2) to be uncoupled from the chamber (100). The first or second action (A1;A2) may each include, but are not limited, to: rotating; pulling; pushing; or unlatching.
