FIELD: smoking accessories.
SUBSTANCE: invention relates to an aerosol generating system comprising a nicotine a source; a volatile delivery enhancing compound source downstream of the nicotine source, wherein the volatile delivery enhancing compound comprises an acid; heating means configured to heat the nicotine source to a temperature of 80 °C to 150 °C; and a physically separate heat transfer barrier between the nicotine source and the volatile delivery enhancing compound source; wherein the heat transfer barrier is configured so that in use the temperature of the volatile delivery enhancing compound source is below 60 °C when the nicotine source is heated by the heating means to a temperature of 80 °C to 150 °C.
EFFECT: technical result is to reduce the reduction of efficiency of nicotine delivery over time.
