“Combustible cigarettes are the most harmful form of nicotine delivery. In the pilot study published, funded by the National Institutes of Health, Carpenter evaluated e-cigarettes in terms of usage, product preference, changes in smoking behaviours and nicotine exposure. Sixty-eight smokers were evaluated: 46 were randomised to use e-cigarettes however they wished, and 22 were randomised to a control group. Results showed that when smokers were given e-cigarettes without any accompanying instructions or requirements for use, uptake was strong, and many participants went on to purchase their own e-cigarettes. Those who used e-cigarettes smoked less and were more likely to quit smoking, as compared to those in the control group.
