         15 . An aerosol-generating article for producing an inhalable aerosol upon heating, the aerosol-generating article comprising:
 an aerosol-forming substrate comprising a gel composition, the gel composition comprising at least one gelling agent, at least one of an alkaloid compound and a cannabinoid compound, and an aerosol former;   an upstream element upstream of the aerosol-forming substrate; and   a recess extending from an upstream end of the aerosol-generating article, through the upstream element, and through at least a portion of the aerosol-forming substrate,   wherein a longitudinal inner surface of the recess is provided with a wrapper.   
     
     
         16 . The aerosol-generating article according to  claim 15 , wherein the upstream element comprises an annular plug comprising fibrous filtration material. 
     
     
         17 . The aerosol-generating article according to  claim 16 , wherein a resistance-to-draw of the upstream element is at least 20 millimetres H 2 O. 
     
     
         18 . The aerosol-generating article according to  claim 15 , wherein at least one of the aerosol-forming substrate and the upstream element is circumscribed by another wrapper. 
     
     
         19 . The aerosol-generating article according to  claim 18 , wherein the another wrapper circumscribing the least one of the aerosol-forming substrate and the upstream element is formed from a same piece of material as the wrapper provided on the longitudinal inner surface of the recess. 
     
     
         20 . The aerosol-generating article according to  claim 15 , wherein a downstream end of the recess is defined by another wrapper. 
     
     
         21 . The aerosol-generating article according to  claim 20 , wherein the another wrapper defining the downstream end of the recess is formed from a same piece of material as the wrapper provided on the longitudinal inner surface of the recess. 
     
     
         22 . The aerosol-generating article according to  claim 15 , wherein a downstream end of the recess is defined by a downstream element, the downstream element comprising a plug of material. 
     
     
         23 . The aerosol-generating article according to  claim 15 , further comprising a mouthpiece assembly downstream of the aerosol-forming substrate. 
     
     
         24 . The aerosol-generating article according to  claim 23 , wherein the mouthpiece assembly is spaced apart from the aerosol-forming substrate. 
     
     
         25 . The aerosol-generating article according to  claim 24 , wherein an upstream end of the mouthpiece assembly is between 1 millimetre and 20 millimetres from a downstream end of the aerosol-forming substrate. 
     
     
         26 . The aerosol-generating article according to  claim 23 , further comprising at least one ventilation zone configured to allow air to enter the aerosol-generating article. 
     
     
         27 . The aerosol-generating article according to  claim 26 , wherein the at least one ventilation zone is disposed about at least one of the aerosol-forming substrate and the mouthpiece assembly. 
     
     
         28 . The aerosol-generating article according to  claim 27 , wherein the at least one ventilation zone is disposed about an upstream end of the mouthpiece assembly.
