On being sucked, the general stem delivers the smoke from the bowl to the user's mouth. Inside the bowl is an inner chamber (2) space holding tobacco pressed into it. This draught hole (3), is for air flow where air has travelled through the tobacco in the chamber, taking the smoke with it, up the shank (4).
The burning process, substances emitted and their levels vary at different temperatures: distillation—the process during which nicotine and aromas are transferred from tobacco to smoke—occurs below 300 °C; pyrolysis occurs around 300 °C–700 °C and involves the decomposition of biopolymers, proteins, and other organic materials and ...
