ABSTRACT:
Thermal indicators for non-combustion smoking articles which chemically react when heated to provide visual indications of temperature changes are disclosed. The indicators comprise organic acids, sugars, or amines combined with sugars. The indicators are printed in a variety of patterns along the length of the smoking articles to show temperature changes and to indicate whether the smoking article is finished and should be discarded.
