E-cigarettes could help some smokers quit “E-cigarettes can help smokers quit or cut down heavily,” The Guardian reports. An international review of the evidence, carried out by the well-respected Cochrane Collaboration, found evidence that they can help some smokers quit.
However, the available body of evidence was slim – just two randomised controlled trials (RCTs), involving around 950 participants.
The two studies found that 9% of people using e-cigarettes with nicotine quit smoking for at least six months, compared to 4% of people using placebo e-cigarettes. However, the results on quitting were only significant when the trials were added together, because so few people managed to quit. The individual trials found no difference in the number of people who quit smoking by at least six months when using e-cigarettes with nicotine compared to placebo e-cigarettes or nicotine patches. The researchers say that the pooled results should therefore be treated with caution.
