^*The filter was removed from the tobacco rod for the heating experiments.

**Coresta unit is defined by the flow of air (cm³ min⁻¹) passing through 1 cm² surface of the paper at a measuring pressure of 1.00 kPa (cm³ min⁻¹ cm⁻² at 1kPa).

***NFDPM stands for “nicotine-free-dry-particulate-matter”; a convention used to compare yields made from machine-smoked cigarettes.
