ABSTRACT:
A method of loading nicotine into porous polymeric items consisting essentially of a polyolefin. The method comprises contacting the items with nicotine or nicotine dissolved in a carrier. The polyolefin item, preferably polyethylene or polypropylene, may be loaded with nicotine by several variations on the basic method. The items may be emplaced in a vessel with nicotine and the vessel then closed for a period of time prior to removal of said items.
A preferred method of producing porous polyethylene items loaded with nicotine comprises first emplacing porous polyethylene items in a vessel. A solution comprising between about 1% nicotine and about 10% nicotine and a solvent for nicotine demonstrating an adherence for polyethylene surfaces is prepared. A quantity of this solution sufficient to contact at least a majority of the polyethylene items is added to the vessel. Excess solution is then drained from the items and the solvent evaporated from the items to produce porous polyethylene items loaded with nicotine.
