Electronic cigarettes (e-cigarettes) as potential tobacco ha rm reduction products: Results of an online survey of e- cigarette users


Abstract Electronic cigarettes (e-cigar ettes), which surged in popularity in 2008, may be the most promising product for tobacco harm reduction yet. E-cigarettes deliver a nicotine vapor without the combustion products that are responsible for nearly all of smoking’s health effects. Other than anecdotal accounts, there is little information about who uses e-cigarettes, and whether people who switch from cigarettes to e-cigare ttes experience changes in symptoms caused by smoking. This pilot online survey, conducted by a UK-based online e-cigarette merchant ( E Cigarette Direct ), investigated e-cigarette use for smoki ng cessation and changes in health status and smoking caused symptoms. A convenience sample (n=303) was enrolled by e-mail and links on various blogs and forums in May-June 2009. The data were analyzed by independent university researchers at the project. All respondents previously smoked and 91% ha d attempted to stop smoking before trying e- cigarettes. Most respondents re sided in the USA (72%) and 21% were in Europe. About half (55%) were 31-50, while 32% were >50 years ol d. Most (79%) of the respondents had been using e-cigarettes for <6 months and reported using them as a complete (79%) or partial (17%) replacement for, rather than in addition to (4%) , cigarettes. The majority of respondents reported that their general health (91%), smoker’s cough (97%), ability to exerci se (84%), and sense of smell (80%) and taste (73%) were better since us ing e-cigarettes and none reported that these were worse. Although people whose e-cigarette use completely replaced smoking were more likely to experience improvements in health and smoking caused symptoms, most people who substituted e-cigarettes for even some of their cigarettes experienced improvements. These are highly motivated and passionate e-cigare tte users who may have different experiences than average e-cigarette users or smokers, and thus the estimates cannot be extrapolated to all smokers or e-cigarette users. However, the resu lts still suggest that ve ry few e-cigarette users are not using them to replace cigarettes and th ere are many switchers and current smokers who could have the reported experience. Unfortuna tely e-cigarettes have been banned in some jurisdictions (e.g., Canada, Victoria (Australia)) where switching from cigarettes to e-cigarettes was documented. The lack of available and legal e-cigarettes may cause some users to resume smoking.

Can one puff really make an adolescent addicted to nicotine? A critical review of the literature.


In the past decade, there have been various attempts to understand the initiation and progression of tobacco smoking among adolescents. One line of research on these issues has made strong claims regarding the speed in which adolescents can become physically and mentally addicted to smoking. According to these claims, and in contrast to other models of smoking progression, adolescents can lose autonomy over their smoking behavior after having smoked one puff in their lifetime and never having smoked again, and can become mentally and physically "hooked on nicotine" even if they have never smoked a puff.
