President Obama smokes: is this cause for worry?

Abstract

This document explores an interesting phenomenon: we look into President Barack Obama's obsession with cigarettes and how he struggled to quit his habit. During the run up to his election campaigns, Barack Obama said to his wife Michelle Obama that he will quit smoking cigarettes. A few months after, he admitted that he has "fallen off the wagon a few times? and said that he won't be smoking in the White House. But ever since he has been elected, President Obama has not quit smoking as he promised.
