E-cigarettes aid quit attempts

Addiction (2014) doi: 10.1111/add.12623

Smokers who used e-cigarettes to quit without support from healthcare professionals are more likely to report continued abstinence than those who used nicotine replacement therapy (NRT) bought over-the-counter (OTC) and those who did not use any cessation aid.

Researchers enrolled adults who had made at least one attempt to quit smoking during the 12 months before the study using e-cigarettes only (n=464), OTC NRT only (n=1922) or no cessation aid in their most recent quit attempt (n=3477). Twenty per cent of those using e-cigarettes reported abstinence, a higher proportion than those using OTC NRT (10.1%, odds ratio [OR] 2.23) or no aid (15.4%, OR 1.38).

After adjusting for confounders, people using e-cigarettes were 63% more likely to quit than those using OTC NRT and 61% more likely to stop smoking than those who did use an aid. E-cigarettes' benefits persisted after adjusting for factors including time since the quit attempt started, age, sex, social grade, abrupt versus gradual quitting, previous quit attempts in the same year and nicotine dependence.
