Katherine Heigl reveals her heart break over smoking to The Washington Post.

"It's so stupid," she said. "I started when I was like 22 or 23, and I had my first cigarette at a bar one night, and I was like mmm. ... I'll try this. I can have just one. I am not gonna get addicted. Then you start bumming. I'm bumming. I don't buy my own packs. I'm not addicted."

"Then you go through something that is hard or difficult or stressful and you buy your first pack and it's all over," said Heigl. "And now it's all about how you're going to quit," she adds. "I've tried everything."

"I've tried Wellbutrin" – a anti-depression drug – "which made me really happy while I smoked. Tried the patch. Tried gum. I hate the gum. It burns my mouth. I think I have to quit the old-fashioned way."
