ABSTRACT:
A filter for tobacco smoke comprises a porous substrate (other than tobacco) having a deposit thereon of particles of a water-insoluble hydrophobic moisture-laden substance which is activated by the smoke of burning tobacco to release the moisture. The filter may be in the form of a cartridge for insertion in a cigarette or cigar holder or as a filter tip made integral with a body of divided tobacco.
