Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what recent research his Department has commissioned or conducted on the health effects of e-cigarettes.

The National Institute for Health Research is currently funding a randomised controlled trial to examine the efficacy of e-cigarettes compared with nicotine replacement therapy, when used within the United Kingdom stop smoking service. The report of the trial is expected to be published in 2018.

Public Health England commissioned a comprehensive independent review of the latest evidence on e-cigarettes from leading academics. Their report, published on 19 August 2015, included the latest evidence on the safety and health effects of e-cigarettes.
