E-<strong>cigarettes</strong>: <strong>an</strong> <strong>evidence</strong> <strong>update</strong>7. Reasons for use <strong>an</strong>d discontinuationReasons for using e-<strong>cigarettes</strong>Reasons for using EC have been assessed for adult smokers <strong>an</strong>d ex-smokers in <strong>an</strong>umber of different ways. Across different populations, help to quit smoking <strong>an</strong>d harmreduction were the top reasons endorsed for using EC [44, 53-57].In the Internet Cohort GB survey, the list of possible reasons for using EC was extendedafter the first year (the survey was carried out in 2012, 2013 <strong>an</strong>d 2014). Nevertheless,the most frequently endorsed reasons were health, to cut down <strong>an</strong>d to quit smoking.These were endorsed <strong>by</strong> approximately 80% of current users at all three time points.The biggest ch<strong>an</strong>ge over time was recorded for ‘they are cheaper’ which appeared to bemore popular in 2014 th<strong>an</strong> 2013 (Table 3). Because of the way the question is phrased,a user endorsing a reason does not indicate that current use is for this particular reason,for example, 80% of current users agree that e-<strong>cigarettes</strong> may help you quit, but thisdoes not me<strong>an</strong> that 80% of all users were using them in a quit attempt.Table 3: Internet cohort GB survey, reasons for using e-<strong>cigarettes</strong> (in order of frequencyof endorsement in 2014)Which of the following were reasons for your usingelectronic <strong>cigarettes</strong>?
