2. Machine-smoked nicotine yields of cigarettes are poor predictors of nicotine intake in smokers. One study found that individuals who smoke low-yield cigarettes received a nicotine exposure eight times greater than that recorded by the smoking machines. Instead of receiving the 0.14 milligram of nicotine recorded by the smoking machine, these individuals received on average 1.17 milligrams per cigarette smoked, while the labels of low-nicotine cigarettes commonly state the nicotine content as 0.1 milligram. Smokers of high-yield cigarettes had an intake that was 1.4 times the machine-smoked amount. These individuals inhaled on average 1.3 milligrams of nicotine per cigarette compared to the 0.91 milligram recorded by the smoking machines and the 1 milligram that appears on the package label of regular brands.
