A device for delivering coffee-derived volatiles to a user, the device comprising: a housing body; a quantity of coffee substance disposed within the housing body such that coffee-derived volatiles are collectable within the housing body from the coffee substance without the use of heat, wherein the quantity of coffee substance is provided in a removable cartridge and wherein the cartridge has at least one puncturable wall,; at least one inlet opening leading to an airway lumen to allow air to flow into the delivery device , wherein the airway lumen leads to a chamber which is configured to hold the cartridge ; at least one outlet opening disposed along the housing body and configured for passage of the coffee-derived volatiles from the housing body; an actuatable mechanism for allowing user actuated delivery of a discrete dose of the coffee-derived volatiles from the housing body to the user's olfactory system, wherein the actuatable mechanism comprises a protrusion configured to activate the cartridge by puncturing the at least one puncturable wall upon actuation so as to allow the delivery of the coffee-derived volatiles , wherein the activation of the cartridge allows the coffee-derived volatiles to enter a volatile lumen which extends to the at least one outlet opening ,wherein the dose of the coffee derived volatiles are sufficient to cause olfactory stimulation of a ventral tegmental area or nucleus accumbens of a brain reward system of the user in an intensity equivalent to an addictive drug, wherein the at least one outlet opening comprises a plurality of outlet openings arranged to provide simultaneous orthonasal and retronasal delivery of the coffee-derived volatiles , characterised in that , a first outlet opening is positioned to direct volatiles toward the oral cavity (OC), and a second outlet opening is disposed at an angle along a side of the volatile lumen or along a side of the chamber to direct volatiles toward the nasal cavity (NC). a housing body; a quantity of coffee substance disposed within the housing body such that coffee-derived volatiles are collectable within the housing body from the coffee substance without the use of heat, wherein the quantity of coffee substance is provided in a removable cartridge and wherein the cartridge has at least one puncturable wall,; at least one inlet opening leading to an airway lumen to allow air to flow into the delivery device , wherein the airway lumen leads to a chamber which is configured to hold the cartridge ; at least one outlet opening disposed along the housing body and configured for passage of the coffee-derived volatiles from the housing body; an actuatable mechanism for allowing user actuated delivery of a discrete dose of the coffee-derived volatiles from the housing body to the user's olfactory system, wherein the actuatable mechanism comprises a protrusion configured to activate the cartridge by puncturing the at least one puncturable wall upon actuation so as to allow the delivery of the coffee-derived volatiles , wherein the activation of the cartridge allows the coffee-derived volatiles to enter a volatile lumen which extends to the at least one outlet opening ,wherein the dose of the coffee derived volatiles are sufficient to cause olfactory stimulation of a ventral tegmental area or nucleus accumbens of a brain reward system of the user in an intensity equivalent to an addictive drug, wherein the at least one outlet opening comprises a plurality of outlet openings arranged to provide simultaneous orthonasal and retronasal delivery of the coffee-derived volatiles , characterised in that , a first outlet opening is positioned to direct volatiles toward the oral cavity (OC), and a second outlet opening is disposed at an angle along a side of the volatile lumen or along a side of the chamber to direct volatiles toward the nasal cavity (NC). <EOS>
