Abstract

A smoking device for releasing an aerosol into the mouth of a smoker comprises in combination, a chamber into which a mixture of air and a liquid aerosol precursor is introduced, a heat source surrounding the chamber, a first duct providing communication between the chamber and a smoker's mouth, whereby the contents of the chamber may be drawn into the smoker's mouth, a container for the aerosol precursor, a second duct means leading from the aerosol precursor container into the chamber whereby aerosol precursor may pass from said container into the chamber, and a third duct means providing communication between ambient air and the chamber whereby ambient air may be drawn into the chamber by the smoker, the arrangement being such that in operation liquid aerosol precursor entering the chamber is converted into a condensation aerosol.
