Daily Cigarette Consumption and Urine Cotinine Level between Dual Users of Electronic and Conventional Cigarettes, and Cigarette-Only Users.
The aim of this study was to identify whether or not the dual users of conventional cigarettes and e-cigs were naturally reducing the amount of their cigarette smoking while they were using e-cigs, and whether their urine cotinine level became similar or less compared to conventional cigarette-only smokers. We used data from the Korean National Health and Nutrition Examination Survey (KNHANES), a nationally representative sample collected in 2014-2016. We selected 2,442 participants who were over 19 years old and were current users of conventional cigarettes and e-cigs. ⋯ Means of urine cotinine level in conventional cigarette-only users and dual users were 1250.35 ng/mL (±832.75) and 1364.95 ng/mL (±827.96), respectively (p < .001). The result of a multiple linear regression analysis identified that dual users' cotinine level was 136.80 ng/mL higher, compared to conventional cigarette smokers' one (p = .011). Unlike the argument that e-cigs can be used as a smoking cessation aid, we found that using e-cigs might be less likely to support quitting smoking or reducing cigarette consumption.
