Professor Des Cox:

We would wholeheartedly agree with that stance as well. The Health Research Board, HRB, completed a review in 2020, which was a systematic analysis of a number of large studies. It concluded that there was no evidence that e-cigarettes were successful at helping people get off tobacco smoking compared to the standard nicotine replacement therapies. Therefore, we would completely agree that the evidence for e-cigarettes as a quitting tool is lacking.
