Summary:
The use of electronic cigarettes by smokers is not associated with greater rates of quitting cigarettes or reduced cigarette consumption after one year, a study shows. More women, younger adults and people with less education used e-cigarettes. E-cigarette use at baseline was not associated with quitting one year later or with a change in cigarette consumption.

The use of electronic cigarettes (e-cigarettes) by smokers is not associated with greater rates of quitting cigarettes or reduced cigarette consumption after one year.

E-cigarettes are promoted as smoking cessation tools, but studies of their effectiveness have been unconvincing.

The authors analyzed self-reported data from 949 smokers (88 of the smokers used e-cigarettes at baseline) to determine if e-cigarettes were associated with more successful quitting or reduced cigarette consumption.

More women, younger adults and people with less education used e-cigarettes. E-cigarette use at baseline was not associated with quitting one year later or with a change in cigarette consumption. The authors acknowledge the low numbers of e-cigarette users in the study may have limited their ability to detect an association between e-cigarettes use and quitting.

"Nonetheless, our data add to the current evidence that e-cigarettes may not increase rates of smoking cessation. Regulations should prohibit advertising claiming or suggesting that e-cigarettes are effective smoking cessation devices until claims are supported by scientific evidence," the authors conclude.
