Abstract
A smoking article () with variable ventilation comprises a mouthpiece () circumscribed by a first wrapper () and a second wrapper (). The first wrapper () and the second wrapper () are substantially air impermeable and are movable relative to one another between a low ventilation configuration and a high ventilation configuration. The mouthpiece () comprises a first airflow pathway () through the first wrapper () or the second wrapper () and a second airflow pathway () through the first wrapper () or the second wrapper (). In the low ventilation configuration airflow into the mouthpiece () through the first airflow pathway () is restricted and airflow into the mouthpiece () through the second airflow pathway () is substantially unrestricted. In the high ventilation configuration airflow into the mouthpiece () through the first airflow pathway () and the second airflow pathway () is substantially unrestricted.
