“…This study, similar to previous studies [5,23,24], found that e-cigarette use was more prevalent among ever conventional cigarette smokers than among never conventional cigarette smokers. In addition, as the frequency and intensity of cigarette smoking increase, the percentage of frequent use of e-cigarette increases.…”

Introduction: The prevalence of adolescent electronic cigarette (e-cigarette) use has increased in most countries. This study aims to determine the relation between the frequency of e-cigarette use and the frequency and intensity of cigarette smoking. Additionally, the study evaluates the association between the reasons for e-cigarette use and the frequency of its use. Materials and Methods: Using the 2015 Korean Youth Risk Behavior Web-Based Survey, we included 6655 adolescents with an experience of e-cigarette use who were middle and high school students aged 13–18 years. We compared smoking experience, the frequency and intensity of cigarette smoking, and the relation between the reasons for e-cigarette uses and the frequency of e-cigarette use. Results: The prevalence of e-cigarette ever and current (past 30 days) users were 10.1% and 3.9%, respectively. Of the ever users, approximately 60% used e-cigarettes not within 1 month. On the other hand, 8.1% used e-cigarettes daily. The frequent and intensive cigarette smoking was associated with frequent e-cigarette uses. The percentage of frequent e-cigarette users (≥10 days/month) was 3.5% in adolescents who did not smoke within a month, but 28.7% among daily smokers. Additionally, it was 9.1% in smokers who smoked less than 1 cigarette/month, but 55.1% in smokers who smoked ≥20 cigarettes/day. The most common reason for e-cigarette use was curiosity (22.9%), followed by the belief that they are less harmful than conventional cigarettes (18.9%), the desire to quit smoking (13.1%), and the capacity for indoor use (10.7%). Curiosity was the most common reason among less frequent e-cigarette users; however, the desire to quit smoking and the capacity for indoor use were the most common reasons among more frequent users. Conclusions: Results showed a positive relation between frequency or intensity of conventional cigarette smoking and the frequency of e-cigarette use among Korean adolescents, and frequency of e-cigarette use differed according to the reason for the use of e-cigarettes.

“…Most Hong Kong residents (83.8%) had heard about e-cigarettes. The prevalence of ever use of e-cigarettes (2.3%) [ 31 ] was similar to Taiwan (3%) [ 32 ] and China Mainland (3.1%) [ 33 ], but lower than many other countries (>6%) [ 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. Previous studies suggested that the low prevalence may be due to the less aggressive e-cigarette promotion than western countries [ 31 , 41 ].…”

This study aimed to gauge the Hong Kong’s public support towards new e-cigarette regulation, and examine the associated factors of the support. We conducted a two-stage, randomized cross-sectional telephone-based survey to assess the public support towards the banning of e-cigarette promotion and advertisement, its use in smoke-free venues, the sale to people aged under 18, and regulating the sale of nicotine-free e-cigarettes. Adults (aged 15 years or above) who were never smoking (n = 1706), ex-smoking (n = 1712) or currently smoking (n = 1834) were included. Over half (57.8%) supported all the four regulations. Banning of e-cigarette promotion and advertisement (71.7%) received slightly less support than the other three regulations (banning of e-cigarette use in smoke-free venues (81.5%); banning of e-cigarette sale to minors (93.9%); sale restriction of nicotine-free e-cigarettes (80.9%)). Current smokers, and perceiving e-cigarettes as less harmful than traditional cigarettes or not knowing the harmfulness, were associated with a lower level of support. Our findings showed a strong public support for further regulation of e-cigarettes in Hong Kong. Current stringent measures on tobacco and e-cigarettes, and media reports on the harmfulness of e-cigarettes may underpin the strong support for the regulation.

However, a lower prevalence of current e-cigarette users was observed in Asia-Pacific countries ranging from 0.8 to 1.3% (Lee et al 2016;Tabuchi et al 2016;Li et al 2015). In Malaysia, e-cigarette made its debut about 10 years ago.…”

E-cigarettes have rapidly gained worldwide popularity. Since its use still poses a health risk to the users, it is important to assess their intention to quit this habit. This study aimed to determine the characteristics of e-cigarette use, its effect on cigarette smoking and users' intention to quit vaping and smoking. A total of 377 e-cigarette users were recruited from three vape retail stores in Bandar Baru Bangi, Selangor. E-cigarette usage pattern, tobacco cigarette consumption and their intention to quit were assessed using a self-administered questionnaire. Most (70%) participants were e-cigarettes only users while 30% were dual users. The median duration of e-cigarette use was 2 (IQR 2) years. Almost all (98.4%) participants used third-generation devices and majority (63.7%) preferred liquid containing 6mg nicotine. About 92% participants, especially heavy smokers, smoked fewer tobacco cigarettes after initiating e-cigarette. Majority (79.6%) of dual users also had reduction in tobacco cigarette consumption with a median current consumption of 5 (IQR 5.0) cigarettes per day. Most (87%) e-cigarette users intend to quit the habit someday. However, many (63.1%) were in the pre-contemplation stage. E-cigarette users of less than 2 years duration tend to have the intention to quit compared to users of more than 2 years (p=0.005). In conclusion, there was more e-cigarette only users than the dual users. E-cigarette use could significantly reduce tobacco smoking, especially among heavy smokers. Most e-cigarette users had the intention to quit vaping but not in the near future and longer e-cigarette use may deter their intention to quit.

Electronic cigarette use among Korean adults

Abstract: E-cigarette use was strongly associated with conventional cigarette use and with frequent heavy drinking. Dual use e-cigarettes and conventional cigarette use as well as the association between heavy alcohol use and e-cigarettes need further exploration.
