                                                Obama still smokes in secret

     US President Barack Obama may have just made life more difficult for cigarette smokers, but he still

smokes every now and then in secret.

      Obama, who has publicly struggled to quit smoking, said he still hasn't completely kicked the habit

even after signing a law this week that will set tough new rules for the tobacco industry.

     "As a former smoker I constantly struggle with it. Have I fallen off the wagon sometimes?  Yes. Am I

a daily smoker, a constant smoker? No," Obama said at a news conference.

     "I don't do it in front of my kids, I don't do it in front of my family. I would say that I am 95 percent

cured, but there are times where I mess up," he said.

      The new law gives the US Food and Drug Administration the power to strictly limit the making and

marketing of tobacco products.

     At a White House signing ceremony Monday, Obama said he was among the nearly 90 percent of

smokers who took up the habit before their 18th birthday.

      "Once you go down this path it's something you continually struggle with, which is exactly why the

law we signed is so important because what we don't want is kids going down that path in the first

place," he said at the news conference.

      Nearly 20 percent of Americans smoke and tobacco use kills about 440,000 people a year in the

United States due to cancer, heart disease, and other serious diseases.
