Are cigarettes flammable?

During the puff of a cigarette in a flammable atmosphere there will be a continuous flow of fuel and air drawn into the combustion zone. Only substances with short ignition delay times, of around 1 millisec or less, at the temperatures encountered in the cigarette, will be expected to be ignited.

Why do cigarettes stop burning?
