Devices, systems, and methods that may be used to controllably deliver alcohol to a subject using an inhaler, wherein the inhaler may include a housing having a flow channel coupled to an ethanol-containing inhalant reservoir, an actuator configured to facilitate release of the inhalant, a constituent sensor, and a control unit. The control unit may accept parameters associated with the subject, create an inhalant delivery regime, and control operation of the actuator based at least partially on a sensed constituent level to facilitate release of an ethanol-containing inhalant from the reservoir into the flow channel in accordance with the regimen.
