1. A vaporization device for use with a vaporizable material, comprising:
a device body;
a power source within the device body;
a microcontroller within the device body; and
a measurement circuit within the device body, wherein the measurement circuit is configured to electrically couple to a resistive heater and measure a resistance of the resistive heaters;
wherein the microcontroller is configured to:
determine a baseline resistance based on the measured resistance, wherein the measured resistance is measured at a time point after a period of time has passed since power from flail the power source was last applied to the resistive heater;
determine a target resistance of the resistive heater based on the determined baseline resistance; and
provide power from the power source to the resistive heater to heat the vaporizable material based at least in part on the target resistance.
