ABSTRACT
In 2010, it was estimated that 19.3% (45.3 million) of the US adult population were smokers; among these, 78.2% (35.4 million) smoked every day and 21.8% (9.9 million) smoked some days. According to the same report, each year, 443,000 people die prematurely either from smoking or being a secondhand smoker, and 8.3 million live suffering from a severe disease because of smoking [1].
