A study published in the National Library of Medicine in the United States found that the use of nicotine-free electronic cigarettes is more effective in promoting smoking cessation than nicotine delivery systems, based on a one-year double-blind randomized trial. The abstract of the paper is compiled by 2FIRSTS below.
The aim of this study was to determine whether using electronic cigarettes to help quit smoking is beneficial for improving the lung health of chronic smokers. The effectiveness of electronic cigarette support in successful smoking cessation attempts was also studied. A total of 210 smokers (78 females) participated in an early lung cancer screening program and were divided into three groups: nicotine electronic cigarette plus support, non-nicotine electronic cigarette plus support, and support only. The results showed that participants in the nicotine electronic cigarette group significantly and rapidly reduced their daily smoking intake, but they relapsed more frequently than the other two groups. Conversely, participants in the other two groups had similar daily consumption levels at both assessment points. Among the participants who quit smoking, only 12 reported coughing, while 48% of current smokers had lung symptoms. Our study suggests that in the long run, using non-nicotine liquids may be beneficial for reducing smoking and may be considered a good option in clinical settings.
