An aerosol generator comprising a body, a mouthpiece on the body and a delivery mechanism delivers aerosol for inhalation by a consumer into the mouthpiece by turning the mouthpiece and body relative to one another. The aerosol is generated from liquid dispensed from a canister having a discharge tube depressible inwardly to open an interior valve. A nozzle member is driven inwardly against the discharge tube of the canister when the mouthpiece and body are turned relative to one another, to open the valve and create the aerosol.
