A device atomizes or vaporizes a liquid for inhalation. A housing has a proximal exit orifice that communicates with an intake orifice. A housing encompasses a reservoir containing a liquid. A wick has a first end in contact with the liquid and a second end that is exposed at an opening in the reservoir. A heater is disposed within housing in an air passage that communicates between the intake orifice and the proximal exit orifice. An actuator responds to a user of the device by placing the heater and the second end of the wick into proximity with the heater to vaporize the liquid.
