Last Night on David Letterman Katherine Heigal introduced David, and all his viewers, to the electronic cigarette. Katherine who adopted 1½-year-old daughter Naleigh from South Korea last year, said she has tried a countless amount of smoking aids, including wearing the patch, chewing nicotine gum and taking a prescription called Chantex – twice.
“I went bananas,” she said, before introducing her newest reliever, an electronic cigarette.
Heigl, 31, went on to inadvertently advertised the electronic cigarette. After Letterman tried the e-cig, he sat back in his chair and tried it again, very calmly.
