Cochrane finds vaping better than NRT
Electronic cigarettes or vaping can increase quit rates compared to nicotine replacement therapy (NRT) according to an updated Cochrane Library review.
The review included 50 completed studies, involving 12 430 people, of which 26 were randomised controlled trials.
There was moderate‐certainty evidence that quit rates were higher in people randomised to e-cigarettes than in those randomised to NRT (risk ratio 1.69, 95% CI 1.25–2.27). E-cigarettes performed even better against behavioural intervention only.
According to the authors, in absolute terms their results show that for every 100 people using nicotine e‐cigarettes to stop smoking, 10 might successfully stop, compared with only six of 100 people using NRT, or four of 100 people having no support or behavioural support only.
None of the included studies detected serious adverse events considered possibly related to e-cigarette use. The most commonly‐reported adverse effects were throat/mouth irritation, headache, cough and nausea, which tended to dissipate over time.
