Abstract

Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.

Claims

1. A method of delivering an aerosol to a subject, the method comprising:

(a) deploying an aerosol generating device comprising a heater and a cartridge comprising a vaporizable material in a vaporization chamber, the vaporizable material comprising fine pieces of tobacco and a vapor forming medium, wherein the fine pieces of tobacco are from 1 mm to 2 mm in diameter;

(b) heating the vaporizable material in the vaporization chamber with the heater of the device using conductive heating to a target temperature;

(c) generating the aerosol in the vaporization chamber, wherein the aerosol contains at least 70% less Hoffman analytes than a common tobacco cigarette; and

(d) delivering the aerosol directly to the subject for inhalation.

2. The method of claim 1, wherein the aerosol comprises particles less than about 2 microns in diameter.

3. The method of claim 1, wherein the Hoffman analytes include:

ammonia, aminonaphthalenes, benzopyrene, formaldehyde, acetaldehyde, acetone, methylethylketone, butyraldehyde, hydrogen cyanide, nitrous oxides, tobacco-specific nitrosamines (TSNAs), pyridine, quinoline, hydroquinone, phenol, cresols, carbon monoxide, 1,3-butadiene, isoprene, acrylonitrile, benzene, toluene, and styrene.

4. The method of claim 1, wherein the target temperature is about 100°

C. to about 200°

C.

5. The method of claim 1, wherein the target temperature is about 150°

C.

6. The method of claim 1, wherein the common tobacco cigarette comprises a filter.

7. The method of claim 1, wherein the aerosol contains at least about 80% less Hoffman analytes than a common tobacco cigarette.

8. The method of claim 1, wherein the aerosol contains at least about 90% less Hoffman analytes than a common tobacco cigarette.
