Tobacco compositions
The invention features tobacco compositions and methods of their use and manufacture. Compositions of the invention may be based on a variety of technologies. Technologies include films, tabs, shaped parts, gels, consumable units, insoluble matrices, and hollow shapes. In addition to tobacco, compositions may also contain flavors, colors, and other additives as described herein. Compositions may also be orally disintegrable. Exemplary compositions and methods of their manufacture are described herein.
