Abstract: An aerosol-generating article for producing an inhalable aerosol upon heating is provided, the aerosol-generating article including: a rod of aerosol-generating substrate; and a downstream section arranged downstream of the rod of aerosol-generating substrate and in axial alignment with the rod of aerosol-generating substrate, the downstream section including one or more downstream elements, the aerosol-generating article being arranged such that a center of mass of the aerosol-generating article is at least 60 percent of the way along a length of the aerosol-generating article from a downstream end.

Abstract: An aerosol-generating article is provided, including: a rod of aerosol-generating substrate including a gel composition including at least one gelling agent, at least one of an alkaloid compound and a cannabinoid compound, and an aerosol former; a mouthpiece element; and an intermediate hollow section between the rod and the mouthpiece element and including: a support element downstream of the rod and including a first hollow tubular segment defining a first longitudinal cavity providing a first unrestricted flow channel, the first segment having at least 1 millimeter wall thickness, and an aerosol-cooling element in axial alignment with the mouthpiece element and abutting an upstream end of the mouthpiece element, the aerosol-cooling element including a second hollow tubular segment having a length of less than 10 millimeters, the second segment defining a second longitudinal cavity providing a second unrestricted flow channel, the first and the second channels being empty.

Abstract: An aerosol-generating article is provided for producing an inhalable aerosol upon heating, the aerosol-generating article including: a rod of aerosol-generating substrate including a gel composition, the gel composition including at least one gelling agent, at least one of an alkaloid compound, and a cannabinoid compound, and at least 50 percent by weight of an aerosol former; an upstream element upstream of the rod of aerosol-generating substrate and abutting the upstream end of the rod of aerosol-generating substrate, in which a resistance-to-draw (RTD) of the upstream element is between 5 millimetres H2O and 80 millimetres H2O; and a downstream section arranged downstream of the rod of aerosol-generating substrate and in axial alignment with the rod of aerosol-generating substrate, the downstream section including one or more downstream elements.
