1. A system, comprising:
a mouthpiece defining a mouthpiece opening;
a reservoir configured to contain carrier material;
a heating assembly including a heating element configured to apply heat to the carrier material; and
a control assembly configured to:
receive target temperature data upon coupling of a cartridge portion to a pen portion, the target temperature data based, at least in part, on an identity of the carrier material contained in the reservoir, the target temperature data including a heating profile based, at least in part, on the identity of the carrier material and associated with a period of continuous suction by a user on the mouthpiece opening, the heating profile including a ramp up portion, a body portion, and a ramp down portion;
upon receiving an indication that a user is applying a first suction to the mouthpiece opening of the mouthpiece, apply a current to the heating element of the heating assembly according to the heating profile such that a temperature of a portion of the carrier material disposed near the heating element rises from a first temperature to a second temperature during a first period associated with the ramp up portion, remains within a predetermined range of the second temperature during a second period associated with the body portion, and decreases from the second temperature to a third temperature during a third period associated with the ramp down portion; and
upon receiving an indication that a user is applying a second suction to the mouthpiece opening of the mouthpiece before the heating element has returned to ambient temperature during the ramp down portion of the application of current to the heating element according to the heating profile, the control assembly is configured to apply an amount of current and/or duration of current to the heating element such that the temperature of the carrier material disposed near the heating element rises to the second temperature, the amount of current and/or the duration of current applied by the control assembly based, at least in part, on a temperature of the heating element at the time of the second suction.
