There is provided a mouthpiece (201) for engaging with a shell (101) to form an electrically heated smoking system, the shell (101) having an electric power supply (103) and electric circuitry (105). The mouthpiece (201) comprises a liquid storage portion (203) with liquid therein, a capillary wick (207) having a first end (207a) and a second end (207b), at least one heating element (209) for heating the second end (207b) of the capillary wick (207), an air outlet (211), and an aerosol forming chamber (213) between the second end (207b) of the capillary wick (207) and the air outlet (211). The capillary wick (207) extends between the liquid and the at least one heating element (209). When the shell (101) and mouthpiece (201) are engaged, the at least one heating element (209) is in electrical connection with the power supply (103) via the circuitry (105), the circuitry (105) is arranged to provide an electric current pulse to the at least one heating element (209) when a user initiates a puff, and a flow route for air is defined from at least one air inlet (115) to the air outlet (211) via the aerosol forming chamber (213), the flow route channelling the air flow around the heating element (209) and the second end (207b) of the capillary wick (207).
