Abstract
Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.
