Devices, systems and methods are provided for delivering coffee-derived volatiles to a user, particularly for the treatment of addiction. The coffee volatiles are selected and delivered by devices and systems which allow for concentrated delivery to the olfactory system of the user in a controlled manner. The olfactory system is the part of the sensory system used for smelling or olfaction. Olfaction of such coffee volatiles in this prescribed fashion stimulates the reward system of the brain such that a specific desired outcome is achieved. In some embodiments, the desired outcome is a reduction in addiction symptoms or curbing of a sensation of addiction withdrawal.
