DEAR ABBY: In a reply to a recent letter about the devastating effects of smoking, you pledge to continue your campaign to discourage young people from starting to smoke.
Here's some help: Some 50 years ago, my scoutmaster demonstrated what happens when you blow smoke through a white handkerchief. I'll never forget the ugly brown stain from just one strong puff.
If everyone who comes in contact with young people performed this demonstration, perhaps some of them would think twice before beginning or continuing to smoke. -- JOHN F. GLASS, STUDIO CITY, CALIF.
DEAR JOHN: Thanks for the help. I remember seeing a similar demonstration many years ago. It was targeted at young people who had not yet started to smoke, and one look was a convincing deterrent because of the amount of tar that appeared on the handkerchief. It took no imagination to see what smoking does to the bronchial tubes and lungs.
