Abstract: A cigarette includes a cigarette portion, a filter portion and a fire extinguishing portion installed therebetween. The fire extinguishing portion has a doughnut shape cross-section and includes a thinner outer peripheral wall and a thicker inner peripheral wall which are radially spaced from each other to form a water storage therebetween. When a smoker wants to extinguish the light after smoking and presses the fire extinguishing portion by applying thereto a force with his fingers, the outer peripheral wall will be broken and then the stored water will fall over the outer surface of a combustible wrapper material of the cigarette portion towards the lower end of the cigarette so that the light of the cigarette can be timely put out by wetting the end portion of the lit cigarette.
