A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes: a refillable PV that is removable from the case; an electrical power source for re-charging a rechargeable battery in the PV; a user-replaceable reservoir for holding e-liquid; and an electrical or electronic pump adapted to transfer e-liquid from the reservoir to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the case has closed and open positions, and lifts up the removable PV when in the open position to enable a user to readily withdraw the PV from the case.

A cartridge for use in a vapor provision system includes an inner container holding a reservoir of fluid to be vaporized, and an outer housing having a mouthpiece formed therein, wherein the outer housing extends in a longitudinal direction along the outside of the inner container for at least a substantial portion of the inner container. The inner container and outer housing are provided with a latch mechanism to retain the inner container within the outer housing.

Apparatus and methods are described for use with a portion of plant material that includes at least one active ingredient. A vaporizing unit includes a heating element configured to heat the plant material, and a sensor configured to detect an indication of airflow rate through the vaporizing unit. Control circuitry is configured to receive an indication of the airflow rate through the vaporizing unit, and, in response thereto, to determine a smoking profile that is desired by the user. The control circuitry drives the heating element to vaporize the active ingredient of the plant material by heating the plant material according to the determined smoking profile. The control circuitry dynamically updates the smoking profile in response to changes in airflow rate over the course of a smoking session. Other applications are also described.
