Abstract
Immobilized diluents in a smoking article are provided, wherein diluents can be immobilized through absorption and/or adsorption of the diluents into immobilizing materials, such as sorbents like silica gels. By immobilizing diluents, the diluents can be available for vaporization, while still being protected from migration and/or loss of the diluents in a smoking article.
