The primary cause of an excessive amount of dottle is a tightly packed or otherwise improperly packed pipe, where the tobacco has been improperly prepared or is compressed and will not burn properly. A second possible cause can be the excessive moisture content of the tobacco and the tobacco being smoked too quickly.
Most pipe tobaccos are less mild than cigarette tobacco, substantially more moist and cut much more coarsely. Too finely cut tobacco does not allow enough air to flow through the pipe, and overly dry tobacco burns too quickly with little flavour. Pipe tobacco must be kept in an airtight container, such as a canning jar or sealed tin, to keep ...

Unlike in North America and the Southern Hemisphere, the water pipe is typically employed by older generations.
Temperatures in burning cigarettes range from about 400 °C between puffs to about 900 °C during a puff. During the burning of the cigarette tobacco (itself a complex mixture), thousands of chemical substances are generated by combustion, distillation, pyrolysis and pyrosynthesis. [1] [2] Tobacco smoke is used as a fumigant and inhalant.
