Preformed cigarette having a specifically defined immobilized flavorant additive insert positioned therein

A preformed cigarette subsequently adapted to deliver a flavorant additive to mainstream smoke during smoking, comprising:

• a tobacco rod having a mouth end and an opposite end to be lit;
• an optional filter attached to said mouth end of said tobacco rod;
• and positioned by insertion with pushing within the opposite end of said tobacco rod of said preformed cigarette at least one thermally degradable, elongated robust preformed immobilized flavorant additive insert in the shape of a rod having a sharpened end which aids insertion with pushing, wherein said insert is sufficiently robust that it maintains its structure when manually or machine inserted with pushing into said tobacco rod of said preformed cigarette without breaking or losing the original shape;
• a completely enclosed internal cavity within said immobilized flavorant additive insert;
• and
• one or more flavorant additive present within said completely enclosed cavity of said immobilized flavorant additive insert in the shape of a rod having a sharpened end which aids insertion with pushing, wherein said insert comprises a hollow polymeric or wooden rod wherein said one or more flavorant additive present therein is protected from loss during storage and said hollow polymeric or wooden rod is capable of releasing said flavorant additive into mainstream smoke during the smoking of the cigarette.
