Obama claims that he hasn't had a cigarette in six years

From Fox News:

The president was caught on camera Monday telling a U.N. official he hasn't had a cigarette in six years.  

"I hope you quit smoking," Obama told Maina Kiai, on the sidelines of the U.N. General Assembly in New York. "I haven't had a cigarette probably in six years. That's because I'm scared of my wife."  

Maybe it just felt like six years. According to statements made by his aides and his family, it's been more like three or four.  

The president first admitted in a June 2009 press conference that he snuck a cigarette now and then, though at the time he was trying to quit.  

Then in February 2010, his White House physician reported that the president was still smoking.  

It appears that sometime in early 2010, the president went cold turkey. The White House reported in December 2010 that Obama hadn't had a cigarette in nine months. . . .
