Abstract: Compositions comprising nicotine and a volatile nicotine-miscible substance may be used to create sources of modulated nicotine vapor. The modulation of nicotine vapor may be one of quantity or of perceived physiological impact or a combination of both. The substance should have a volatility somewhat similar to that of nicotine and have a normal boiling point between about 175.degree. C. and about 275.degree. C. These compositions may be placed in the nicotine reservoir of a personal oral nicotine inhaler. Esters are preferred nicotine miscible substances, particularly when substantially flavorless and generally recognized as safe for human consumption. Nicotine and nicotine-miscible substance in a weight/weight ratio between about 0.5 and 40.0 are emplaced in a nicotine reservoir, for example absorbed in a porous polyethylene item, for insertion into the tubular passageway of a smokeless cigarette.

Abstract: An oral nicotine dispenser comprising nicotine or a nicotine salt and a water-insoluble material capable of sorbing nicotine. The dispenser is able to slowly release the sorbed nicotine or nicotine salt in an oral environment. The water insoluble material may consist essentially of paper or a polymeric substance able to absorptively contain nicotine.The water-insoluble material may be a substance such as paper or cellulose acetate. A water-insoluble polymeric substance such as a polyolefin, most preferably polyethylene or polypropylene may be used as the nicotine-holding material.

Abstract: A nicotine-enhanced smoking article having a first tobacco portion and a second filter portion attached thereto. The filter portion containing filter fibers and a nicotine solution having 5-15%, by weight of total solution, nicotine or a nicotine salt in a solvent. The interaction of the combination products from the first portion with the nicotine solution results in the absorption by the combustion products of nicotine from the solution providing increased nicotine to the user.

Abstract: An improved snuff containing substantially pure powdered salts of nicotine diluted with powdered organic sugars which is substantially absorbed by the nasal membranes when applied thereto. Flavoring and/or coloring agents are optionally present. The improved snuff is prepared by adding an acid to a nicotine solution, separating the nicotine salt from the solution, diluting the nicotine salt to a usable concentration, and optionally adding flavoring and/or coloring agents to enhance the fragrance and appearance of the improved snuff.
