Is Obama a Smoker?

I heard Barack Obama used to smoke a lot before he became president of the United States.
I talked about this with my dad who reads about politics everyday and he said Obama is not a smoker anymore. Is it true?
Do you think Obama is still smoking while hiding and denying it?

Yes, he is a smoker.
Obama said in a Reuters interview that he still hasn't completely kicked the habit.
He admitted that he is not above sneaking a smoke every now and again, even though he may have just made life more difficult for cigarette makers.

This whole smoking issue is hard for Obama.
I read he's not such a hardcore smoker anymore like he used to.
While he doesn't smoke every day or in front of his family, he admitted “there are times when I mess up.” Right now, Obama said he's about 95 percent cured.

Sure he smokes, not a big deal except for the tobacco haters.
He admitted on Tom Brokaw that he still does. He tried to lie about it, but Brokaw made him confess and tell the truth.
Some of our greatest presidents have been smokers.
