Daily Cigarette Consumption and Urine Cotinine Level between Dual Users of Electronic and Conventional Cigarettes, and Cigarette-Only Users.

Introduction:
This text is a summary of a research study examining the relationship between cigarette consumption, urine cotinine level, and the use of electronic cigarettes (e-cigs) among dual users (those who smoke both conventional cigarettes and e-cigs) and conventional cigarette-only smokers. The study aims to understand the smoking behavior of dual users and the potential impact of e-cigs on smoking cessation.

Key Points:

* The study used data from the Korean National health and Nutrition Examination Survey (KNhaNES) conducted in 2014-2016.
* The study selected participants who were over 19 years old, current users of conventional cigarettes and e-cigs, and smoked more than 5 packs of cigarettes in their whole life.
* The study found that conventional cigarette-only users smoked 14.26 (±23.19) cigarettes a day, while dual users smoked 14.46 (±7.88) cigarettes a day.
* The study also found that the 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.
* The study conducted a multiple linear regression analysis, which identified that dual users' cotinine level was 136.80 ng/mL higher compared to conventional cigarette smokers' one.
* The study suggests that using e-cigs might be less likely to support quitting smoking or reducing cigarette consumption.
* The study highlights the importance of using scientifically proven smoking cessation programs and methods instead of relying on unproven alternatives, such as e-cigs.

Main Message:
The main message of this study is that using e-cigs as a smoking cessation aid might not be effective in reducing cigarette consumption or supporting quitting smoking. Instead, the study suggests that scientifically proven smoking cessation programs and methods should be used to quit smoking. The study also emphasizes the importance of monitoring and controlling tobacco industry marketing and promotion of e-cigs and health claims associated with e-cigs. Overall, the study highlights the need for further research on the relationship between e-cig use and smoking cessation, particularly in prospective studies comparing nicotine exposure between cigarette-only smokers, dual users of cigarettes and e-cigs, and e-cig only users.
