Smoking substitute system

Abstract

A consumable for a smoking substitute device is disclosed that contains a liquid aerosol-forming substrate, wherein the substrate comprises solid tobacco-derived material and a solution of nicotine which has been released from the tobacco-derived material. Also disclosed are a method for manufacturing the consumable for a smoking substitute device and a vaping smoking substitute device configured for vaping the liquid aerosol-forming substrate.

1 . A consumable for a smoking substitute device, comprising:
 a liquid aerosol-forming substrate that comprises solid tobacco-derived material and a solution of nicotine released therefrom.   
     
     
         2 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate comprises a suspension of solid tobacco-derived material in a solution of nicotine which is obtained from nicotine-free liquids. 
     
     
         3 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate contains at least 20 mg of solid tobacco-derived material per ml of liquid. 
     
     
         4 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate contains up to 130 mg of solid tobacco-derived material per ml of liquid. 
     
     
         5 . The consumable according to  claim 1 , wherein the liquid-aerosol forming substrate contains from 0.1 to 20% by weight of solid material. 
     
     
         6 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate contains at least 2.0 mg/ml of nicotine. 
     
     
         7 . The consumable according to  claim 6 , wherein the liquid aerosol-forming substrate contains at least 3.0 mg/ml of nicotine. 
     
     
         8 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate contains solid tobacco-derived material obtained from tobacco leaf and/or tobacco stem. 
     
     
         9 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate comprises solid tobacco-derived material having a size in a range of 20 μm to 2000 μm. 
     
     
         10 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate comprises from 0.1 to 70% by weight of propylene glycol and 0.1 to 70% by weight of glycerine. 
     
     
         11 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate has been subjected to process conditions in the presence of aerosol former liquid in order to enhance release of nicotine from the solid tobacco-derived material into the liquid to form a nicotine-containing solution. 
     
     
         12 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate contains flavourings and/or aroma components which are not derived from tobacco. 
     
     
         13 . The consumable according to  claim 1 , wherein the liquid aerosol-forming substrate is visible. 
     
     
         14 . The consumable according to  claim 1 , which forms part of a closed system device in which liquid aerosol-forming substrate is stored in a tank which is not adapted for refilling. 
     
     
         15 . The consumable according to  claim 1 , wherein the consumable forms part of an open system device in which liquid aerosol-forming substrate is stored in a tank which is adapted for refilling. 
     
     
         16 . A method for manufacturing a consumable for a smoking substitute device, wherein the method comprises the steps of:
 combining solid tobacco-derived material and aerosol former liquid to form a mixture; and   subjecting the mixture to process conditions which enhance release of nicotine from the tobacco-derived material into the aerosol former liquid; and   wherein the consumable comprises a liquid aerosol-forming substrate that comprises solid tobacco-derived material and a solution of nicotine released therefrom.   
     
     
         17 . A vaping smoking substitute device configured for vaping a liquid aerosol-forming substrate, wherein the liquid aerosol-forming substrate comprises solid tobacco-derived material and a solution of nicotine released therefrom.
