People who quit smoking reduce their risk of disease and those who quit at an earlier age see the most health benefits [23]. An estimated 69 % of the approximately 45 million smokers in the United States want to stop smoking [24, 25]. Nonetheless, smoking cessation success rates remain discouragingly low; in 2010, only 6.2 % of adult smokers attempting to quit were successful [25]. For those seeking to quit, there are a variety of counseling methods and cessation medications available [26, 27].
