Abstract: A volatile material vaporizing apparatus features a heating element and heating element controls supported in separate housings to avoid exposure of the controls to heat produced by the heating element. Another embodiment features an elongate heating element supported entirely within a housing having an open end sized to fit over the bowl of an existing smoking device so that drawing air through the smoking device induces airflow into an inlet opening of the housing, along the heating element disposed therein, and onward to the smoking device. In another embodiment, a housing includes a plug portion slidable into a cigarette lighter socket of a vehicle to establish connection with electrical contacts therein. A heating chamber opposite the plug portion is in fluid communication with a heating element in the housing, and an inlet opening allows airflow into the housing for flow along the heating element into the heating chamber.
