Katherine Heigl is a quitter.
The actress, who left Grey's Anatomy earlier this year, is trying to quit her smoking habit the hi-tech way.
"I use an electronic cigarette," Heigl, 31, tells Parade.com of SmokeStik. "I know it's ridiculous, but it's helping me [avoid smoking] real cigarettes. You feel like you are smoking, and you get to exhale but it's just water vapor and not nicotine. I've been doing it for six months."
"Smoking sucks!" exclaims the Life As We Know It star, who has an adopted 22-month-old daughter, Naleigh, with her musician husband Josh Kelley.
"The one thing I would say to my kid is, 'It's not just that it's bad for you," adds Heigl, who claims cigarettes aren't all that fun in the first place.
"'Do you want to spend the rest of your life fighting a stupid addiction to a stupid thing that doesn't even really give you a good buzz?'"
Heigl even puffed on a "smoke stick" during her appearance last Monday on the Late Show With David Letterman. She told David Letterman about how her smoking habit began in the first place.
"You start once a week, maybe with cocktails with friends at a bar...And then you buy your first pack during a really stressful breakup and then it's downhill from there."
Before e-cigarettes, Heigl futilely tried just about every other remedy on the market, she told the late-night comic: the patch, chewing nicotine, even the prescription medication Chantex.
Only the "smoke stick" seems to work for her, she said. "You're not harming anyone around you and you're not harming yourself. I'm essentially humidifying the space."
