Abstract
Abstract An improved nicotine dispensing device for non-pyrolytic use which is adapted to release nicotine bearing vapors into air drawn through the device. The device includes a housing and a plurality of microporous polymer filaments which are nicotine loaded. The microporous polymer filaments are characterized by a relatively homogeneous, three-dimensional cellular microstructure. The microporous polymer filaments are made from materials which are selected from olefinic polymers, condensation polymers, oxidation polymers and combinations thereof.
