Abstract: A device for discouraging cigarette smoking is disclosed comprising a cigarette filter having a mouthpiece oppositely disposed from a cigarette holder with a passageway therebetween. A filter paper is treated to be invisibly pervious only within the configurations of the letters of a word or words directed to the dangers of smoking. The treated filter paper is located in said passageway to close the free passage of smoke from the cigarette holder to the mouthpiece.The method of discouraging cigarette smoking is disclosed comprising the use of the foregoing structure wherein a cigarette is placed in the cigarette holder, the cigarette is lighted, and the smoke is withdrawn from the lighted cigarette so that the smoke from the lighted cigarette will move from the cigarette through the pervious portions of the filter paper, whereupon the letters of the words will entrap smoke particles so as to make the letters of the word or words visible.
