Abstract
A heated aerosol-generating article for use with an aerosol-generating device is provided, including a plurality of components including an aerosol-forming substrate assembled within a wrapper to form a rod having a mouth end and a distal end upstream from the mouth end, the heated aerosol-generating article defining a first air-flow path in which air drawn into the aerosol-generating article through the mouth end passes through the aerosol-forming substrate, and a second air-flow path in which air drawn into the aerosol-generating article through the mouth end does not pass through the aerosol-forming substrate, the resistance to draw (RTD) of the second air-flow path being lower than the RTD of the first air-flow path when the heated aerosol-generating article is not coupled to an aerosol-generating device.
