1. An apparatus, comprising: a heat chamber configured to heat smokable material in the heat chamber, the apparatus being operable in a first configuration to allow a gaseous flow between an interior of the heat chamber and an exterior of the heat chamber and operable in a second configuration to prevent the gaseous flow by hermetically sealing the heat chamber, wherein the heat chamber includes an inlet and an outlet configured such that, when the apparatus is in the first configuration, the inlet and the outlet are open and permit gaseous flow through the inlet and the outlet, and when the apparatus is in the second configuration, the inlet and the outlet are closed and hermetically seal the heat chamber and prevent gaseous flow through the inlet and the outlet; a heater configured to heat the smokable material within an interior of the heat chamber without combusting the smokable material to volatilize at least one component of the smokable material; a mouthpiece; a puff sensor configured to detect when a puff occurs at the mouthpiece and generate a puff indication; and a controller configured to open the inlet and/or the outlet in response to the puff indication at the mouthpiece and close the inlet and/or the outlet in response to an end of the puff.
