Reasons why Chinese smokers prefer not to use electronic cigarettes

INTRODUCTION: China is the world’s largest e-cigarette manufacturer. It also has the world’s largest smoking population. Although smoking is strongly associated with e-cigarette use, the prevalence of e-cigarette use is low among Chinese smokers compared with smokers in countries such as the US and UK. This study aims to explore the reasons why Chinese smokers prefer not to use e-cigarettes. METHODS: Cross-sectional data from the Tobacco Questions for Surveys (TQS) conducted in four large Chinese cities (Chengdu, Wuhan, Xiamen, and Xi’an) in 2017–2018 were analyzed. A multi-stage cluster sampling approach was applied to select a representative sample of adults for each city. Weighted percentages and 95% confidence intervals (CIs) were estimated for self-reported reasons why smokers in China had never tried e-cigarettes, in total and by demographic characteristics. Multivariate logistic regression models were used to examine the adjusted associations between the top reasons why smokers never tried e-cigarettes and demographic and socioeconomic characteristics. RESULTS: The top three reasons that Chinese adult smokers reported for never having tried e-cigarettes were: ‘I do not want to quit smoking’ (35.35%), ‘I do not think they would help me quit or cut down’ (24.31%), and ‘I am not addicted to smoking and don't need help to quit’ (14.93%). Other prominent reasons included: ‘I am concerned they are not safe enough’, and ‘I do not want to substitute one addiction for another’. Generally, there were no statistically significant associations between reasons why smokers never tried e-cigarettes and demographic and socioeconomic characteristics. CONCLUSIONS: Our results suggest that many Chinese smokers associate e-cigarette use with smoking cessation. Continued monitoring of smokers’ views, beliefs, and risk perceptions regarding e-cigarettes is warranted. Health education campaigns communicating the risks of e-cigarettes are also needed.
