1. An electronic smoking device comprising the following:

  • a body through which a flow path at least partially extends;

    an air inlet in the body that is fluidly connected to the flow path;

    a liquid compartment for storing a liquid within the body;

    a vaporizer positioned in the body and configured to receive liquid from the liquid compartment and air from the flow path to generate vaporized liquid;

    an outlet in the body configured to receive vaporized liquid from the vaporizer;

    an airflow sensor configured to detect a flow of air through the flow path indicative of a user action;

    an active dispensing device configured to control flow from the liquid compartment;

    controller circuitry connected to the vaporizer, the airflow sensor, and the active dispensing device, the controller circuitry configured to activate the active dispensing device in response to a signal from the airflow sensor indicative of the user action, and thereby control dosage of vaporized liquid, wherein the circuitry is further configured to transmit a disabling signal to the airflow sensor, and the airflow sensor is further configured, in response to the disabling signal from the controller circuitry, to stop airflow through the flow path.
