Take a Deep Breath

Oprah and Dr. Oz are kicking off a campaign to help 45 million Americans "Breathe Free" and stop smoking—for good! But first, eight of the show guests take their last cigarette drags before making the commitment.

Standing outside on a bone-chilling Chicago winter morning, they admit to a range of shocking emotions—all a reflection of their smoking addiction.

"It is most embarrassing."

"I'm a nervous smoker, and I'm going to smoke more because I'm scared. Just talking about quitting freaks me out."

"[Quitting] is like a grieving process. It's like losing a best friend."
