The prevalence of smoking has declined dramatically in America over the last half century, falling from about 42% in the 1960s to about 20% today2. However, this decline has stalled recently, and higher prevalence rates are concentrated in certain populations: those with low incomes, low educational attainment, psychiatric conditions, and certain ethnic groups such as Native Americans. Fortunately, most evidence shows that individuals in these populations are aided by the same treatments that are effective in other smokers3.
