Abstract
Fibrous structures composed of electrostatically prepared polysaccharide micro- and nanofibers are described which contain active agents such as drugs and/or flavorants encapsulated within the structures. When exposed to moisture, the structures are disrupted and the active agent rapidly released. The fibrous structures containing active agents such as flavorants can be incorporated into smoking articles which, when smoked, release the flavorants.
