An electronic smoking device comprises 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, and circuitry connected to the vaporizer and configured to control dosage of vaporized liquid. A method for controlling dosage in an electronic smoking device comprises sensing an airflow, releasing a liquid into the airflow, activating a vaporizer to generate vaporized liquid, and controlling flow of airflow, liquid or vaporized liquid to control dosage. ## Claims ### Claim 1 A method for controlling dosage in an electronic smoking device, the method comprising: sensing an airflow through a flow path in a body; releasing a liquid from a compartment into the airflow; receiving the liquid and the airflow at a vaporizer; activating the vaporizer to generate vaporized liquid; and controlling airflow through the body with a sensor to limit dosage. ### Claim 2 (depends on 1) The method of claim 1, further comprising controlling activation of the vaporizer to limit dosage. ### Claim 3 (depends on 2) The method of claim 2, wherein cumulative activation of the vaporizer is limited. ### Claim 4 (depends on 2) The method of claim 2, wherein periodic activation of the vaporizer is limited. ### Claim 5 (depends on 2) The method of claim 2, further comprising operating the vaporizer according to time data stored in memory of a controller connected to the vaporizer. ### Claim 6 (depends on 2) The method of claim 2, further comprising detecting a user action with a sensor connected to the vaporizer to control dosage. ### Claim 7 (depends on 1) The method of claim 1, further comprising controlling dispensing of liquid from the compartment to the vaporizer to limit dosage. ### Claim 8 (depends on 7) The method of claim 7, further comprising dispensing a predetermined amount of liquid. ### Claim 9 (depends on 8) The method of claim 8, further comprising dispensing the same amount of liquid per user action. ### Claim 10 (depends on 7) The method of claim 7, further comprising detecting a user action with a sensor controlling a dispensing device to control dosage. ### Claim 11 (depends on 1) The method of claim 1, wherein controlling flow of airflow, liquid or vaporized liquid to control dosage per unit time includes disabling the vaporizer in response to the heater on time during a given period of time exceeding a threshold limit. ### Claim 12 A method for controlling dosage in an electronic smoking device, the method comprising: sensing an airflow through an air inlet and a flow path in a body of the electronic smoking device; releasing a liquid from a liquid compartment in the electronic smoking device into the airflow; receiving the liquid and the airflow at a vaporizer positioned in the body; and controlling dosage by disabling the vaporizer when activation time of the vaporizer exceeds a predetermined period of time indicative of a predefined life of the vaporizer. ### Claim 13 A method for controlling dosage in an electronic smoking device, the method comprising: sensing an airflow through an air inlet and a flow path in a body of the electronic smoking device; releasing a liquid from a liquid compartment in the electronic smoking device into the airflow; receiving the liquid and the airflow at a vaporizer positioned in the body; and controlling dosage by disabling the vaporizer when activation time of the vaporizer exceeds a predetermined period of time indicative of a predefined life of the vaporizer, and wherein the step of controlling dosage includes determining how long the vaporizer has been cumulatively active, activating the vaporizer if the vaporizer has been activated a cumulative amount of time less than a predetermined total time limit, and permanently disabling the electronic smoking device if the cumulative amount of time the vaporizer has been activated is equal to or greater than the predetermined total time limit.
