1. A method of efficiently and consistently vaporizing a precise volume of a liquid medicant from a hand-held device, comprising: a. determining a precise amount of power required to vaporize the precise volume of liquid with the heating element in a precise duration of time; andb. metering a precise volume of a liquid to a heating element;c. supplying the precise amount of power from a power supply to heat the heating element for the precise duration of time such that the combination of the precise amount of power and the precise duration of time heats the heating element to a minimum required temperature for a minimum required time to completely vaporize the precise volume of the liquid;d. monitoring a temperature of the heating element while the power is being supplied;e. comparing the temperature of the heating element to the minimum required temperature; andf. adjusting the precise duration of time or the precise amount of power based on the comparison step to completely vaporize the liquid, wherein if the precise volume of liquid is adjusted, the precise duration of time or the precise amount of power is adjusted to completely vaporize the adjusted precise volume of liquid within a new minimum required temperature for a new minimum required time. 2. The method of claim 1, wherein metering a precise volume of the liquid, comprises: a. storing the liquid in a fluid reservoir; andb. applying a precise amount of positive pressure inside the fluid reservoir to discharge the precise volume of fluid from the fluid reservoir. 3. The method of claim 2, wherein the precise amount of positive pressure is applied by advancing a threaded plunger a predetermined distance within the fluid reservoir. 4. The method of claim 3, wherein advancing the plunger the predetermined distance is achieved by turning a drive nut a fixed rotational movement, wherein the threaded plunger comprises a groove running down a length of the threaded plunger, and an anti-rotation tang is seated within the groove to prevent rotation of the threaded plunger. 5. The method of claim 4, wherein turning the drive nut is achieved by actuating a button that turns the drive nut the fixed rotational movement each time the button is actuated, wherein the drive nut remains in a fixed translational location. 6. The method of claim 1, wherein supplying the precise amount of power is achieved by programming a processor to permit actuation of the power supply a predetermined number of times. 7. The method of claim 1, wherein monitoring the temperature of the heating element is achieved by measuring the resistance in the heating element. 8. The method of claim 1, further comprising a supercapacitor operatively connected to the power supply and a processor to limit the amount of power supplied to generate the minimum required temperature. 9. The method of claim 8, wherein the power supply is an alkaline battery. 10. The method of claim 1, wherein supplying the power is activated by creating an airflow at a mouthpiece of the hand-held device. 11. The method of claim 10, further comprising controlling a size of a vapor molecule of the vaporized liquid by placing a permeable membrane between the heating element and the mouthpiece, wherein the permeable membrane is permeable only to vapor molecules of a predetermined size.
