"Although many smokers have confirmed that they have successfully quit smoking with the help of electronic cigarettes, health professionals do not want to recommend use for lack of clear evidence of randomized clinical trials. It's likely to change from now on, "said Peter Hike, a researcher at Queen Mary University in London, who led the research.

In the clinical trial 886 smokers participated who went to health centers in search of help to give up. Doctors distributed them randomly in two groups. In the first group, they were replaced with nicotine at their own choice, such as patches, chewing gum, tablets or inhalers, which should last up to three months. In the second group, smokers received an electronic cigarette pack with accessories and were encouraged to buy the flavors they liked most. Additionally, all participants received support sessions with healthcare staff for four weeks.
