 an aerosol-generating substrate,   a downstream section extending from a downstream end of the aerosol-generating substrate to a downstream end of the aerosol-generating article; and   an upstream section extending from an upstream end of the aerosol-generating substrate to an upstream end of the aerosol-generating article,   wherein the upstream section comprises an aversive agent.   
     
     
         2 . An aerosol-generating article according to  claim 1 , wherein the aversive agent comprises at least one of denatonium benzoate (bitrex), columbin, amarogentin, quassin, absinthin, and quinine hydrochloride. 
     
     
         3 . An aerosol-generating article according to  claim 1 , wherein the aversive agent is provided in a concentration of at least 2 parts per million. 
     
     
         4 . An aerosol-generating article according to  claim 1 , wherein the aversive agent is provided on a solid aversive component. 
     
     
         5 . An aerosol-generating article according to  claim 4 , wherein the aversive component comprises a substrate, the aversive agent being absorbed on the substrate. 
     
     
         6 . An aerosol-generating article according to  claim 5 , wherein the substrate is a thread substrate, the aversive agent being absorbed in the thread substrate. 
     
     
         7 . An aerosol-generating article according to  claim 1 , further comprising at least one ventilation zone downstream of the upstream section to allow air to enter the aerosol-generating article. 
     
     
         8 . An aerosol-generating article according to  claim 4 , wherein the upstream section further comprises a plug circumscribed by a wrapping paper. 
     
     
         9 . An aerosol-generating article according to  claim 8 , wherein the aversive component is embedded in the plug of the upstream section. 
     
     
         10 . An aerosol-generating article according to  claim 8 , wherein the plug of the upstream section comprises at least one of cellulose acetate fibres, polylactic acid fibres, polyhydroxybutyrate fibres, and polyhydroxyalkanoate fibres. 
     
     
         11 . An aerosol-generating article according to  claim 8 , wherein the plug is a solid plug and has a resistance to draw of at least 50 millimetres H 2 O. 
     
     
         12 . An aerosol-generating article according to  claim 8 , wherein the upstream section further comprises an airflow channel extending through the plug from the upstream end of the plug to the downstream end of the plug. 
     
     
         13 . An aerosol-generating article according to  claim 12 , wherein the upstream section further comprises a tube defining the airflow channel. 
     
     
         14 . An aerosol-generating article according to  claim 12 , wherein a diameter of the airflow channel is at least 45 percent of a total external diameter of the upstream section. 
     
     
         15 . An aerosol-generating article comprising:
 an aerosol-generating substrate,   a downstream section extending from a downstream end of the aerosol-generating substrate to a downstream end of the aerosol-generating article, and   an airflow pathway through which air may enter the aerosol-generating article, pass through the aerosol-generating substrate, and exit the aerosol-generating article through the downstream section,   the aerosol-generating article further comprising an aversive agent, the aversive agent being provided at a location within the aerosol-generating article such that the aversive agent is not directly exposed to the airflow pathway.
