<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The concentration of gas-vapour phase components of cigarette smoke increases almost throughout from the beginning to the end of each puff, as produced on a piston-actioned smoking machine.

This indicates without any doubt that the concentration in volatile components increases from the beginning to the end of a puff. This effect is increased as the smoking progresses towards the butt end of the cigarette. The yield of the crude smoke condensate is about the same in each third of a puff.
