Abstract: Method and device for volatilising active and/or aroma materials for the purpose of releasing an inhalable aerosol, wherein a fluid flows through a flow channel (11) in a preferably cylindrical hollow body (1) and wherein the fluid in this flow channel entirely or in part flows through at least one vaporiser membrane (2), wherein the at least one vaporiser membrane has been and/or is wetted with a substance containing an active and/or aroma material to be vaporised and wherein the fluid additionally containing thermal energy vaporises this substance on flowing through the vaporiser membrane and supplies it to the fluid stream.

Abstract: A method for volatilising active and/or aroma substances for the purpose of releasing an inhalable aerosol, wherein combustion gases of a flammable gas, which is preferably combusted with an excess of air, are passed partially or entirely, optionally mixed with ambient air, through an active and/or aroma substance depot and wherein a desired temperature is selectable by the proportion of combustion gases and optionally by the mixing ratio of said combustion gases with ambient air and the device implementing the method in the shape and dimensions of a cigarette or cigar for releasing an inhalable aerosol, comprising a mouthpiece (3) containing an active and/or aroma substance depot (32), a heating member (2) with a housing sleeve with one or more air inlets and one or more hot air outlets at the mouthpiece end, a filling valve (21) for filling a gas tank (22) with a flammable gas, preferably propane or butane gas, a regulating valve (24) for the controlled release of the gas from the gas tank (22) to a burner
