(CNN) - The president may have kicked his smoking habit once and for all. It has been about nine months since the president's last cigarette, according to White House Press Secretary Robert Gibbs.
In an interview on CNN's "State of the Union," Gibbs said he still chews Nicorette, but that the president used "stubborn willpower" to stop.
Gibbs also said this is the longest period, in the almost eight years he's known the president that he's gone without smoking.
"It's really stuck," Gibbs said.
