Aerosol generation

An aerosol generating article for use in an aerosol generating assembly, the article comprising an aerosol generating substrate comprising an aerosol generating material, wherein the aerosol generating material comprises an amorphous solid, the amorphous solid comprising:

• 10-60 wt % of a gelling agent;
• 5-60 wt % of an aerosol generating agent;
• and
• 40-60 wt % of a tobacco extract;
• wherein these weights are calculated on a dry weight basis;
• wherein the aerosol generating substrate comprises a carrier on which the amorphous solid is provided, and the carrier provides a non-tacky surface for the aerosol generating material;
• and
• wherein the carrier is disposed so as to have a rougher side abutting the amorphous solid and a smoother side facing away from the amorphous solid.
