The invention relates to an aerosol delivery system for delivering aerosolised medicament particles to a user comprising a cartridge and a device configured to receive the cartridge. The cartridge comprises: a first compartment comprising a delivery enhancing compound source； a second compartment comprising a medicament source； a vaporiser for heating the medicament； and a transfer element for conveying the medicament from the second compartment to the vaporiser. The cartridge may further comprise an aerosol forming chamber in fluid communication with the first compartment and the second compartment. The device comprises: an outer housing； a power source； temperature controlling means for controlling the temperature of the first compartment of the cartridge； and electronic circuitry configured to control power to the temperature controlling means from the power source. The electronic circuitry is configured to maintain the first compartment of the cartridge at a temperature of between about 30°C and about 50°C. In use, the medicament reacts with the delivery enhancing compound in the gas phase to form aerosolised medicament-containing particles.
