The trial consisted of a 6-week randomized, placebo-controlled clinical trial of nicotine gum, consisting of 255 adult ITS (131 nicotine gum, 124 placebo) seeking help for smoking cessation. The researchers looked into the outcome of temptation episodes where gum was or was not used.
The participants reported a total of 2,713 temptation episodes, 46.0% (1,248) of which resulted in smoking (lapsing). The compiled data indicated that using nicotine gum decreased the odds of lapsing by 55% compared with using placebo (OR=0.45, 0.22-0.94).
E-Cigs twice as effective as other NRTs
The researchers followed nearly 900 smokers through their quit attempts. All adults attending NHS smoking cessation clinics were randomly divided into two groups. Members of one group were given a conventional Nicotine Replacement Therapy (NRT) of their choice such as nicotine gum or patch (including combinations of products if they wanted it) while the other group were given e-cigarettes. In addition, both groups were also offered behavioural support.
After one year the participants were assessed for smoking status, including biochemical tests to ensure that those who claimed to have quit smoking, really had. At the one year mark, the NRT group had a 9.9% abstinence rate at one year, this was considered surprisingly high, given that previous studies had found NRT to be only 5-7% effective. However, the e-cigarette group were almost twice as successful, with an abstinence rate of 18%.
