1. An aerosol generating device, the device comprising an elongated housing comprising:
- a. a reservoir comprising a liquid substrate comprising nicotine and a carrier;
b. an air flow channel comprising;
i. a first air inlet;
ii. a heater element, wherein the heater element comprises a coil wrapped around a wick element, wherein the coil and wick element are made of an electrically resistive material that when heated vaporizes the liquid substrate comprising nicotine and a carrier that is delivered onto the heater element;
iii. a tube located within the air flow channel;
wherein the tube is in fluid communication with the reservoir and the heater element; and
iv. an outlet, wherein the heater element is located in an aerosol generation region of the air flow channel between the inlet and the outlet, and wherein the device is configured to emit a condensation aerosol comprising nicotine and a carrier from the outlet;
v. a second air inlet, wherein the second air inlet is located between the aerosol generation region and the outlet;
c. a pump connected to the tube, wherein the pump is configured to deliver the liquid substrate comprising nicotine and the carrier through the tube onto the heater element;
d. an air flow switch, wherein the air flow switch is configured to activate the heater element at an air flow rate through the aerosol generating region of less than 1 LPM; and
e. a power supply, wherein the power supply is in electrical communication with the heater element and the air flow switch.
