Clearing the air: protocol for a systematic meta-narrative review on the harms and benefits of e-cigarettes and vapour devices

Discussion Meta-narrative synthesis has the unique capacity to expose the debates that are influencing the interpretation of empirical studies on vapour devices. We seek to “clear the air” with an even-handed review of the evidence and an understanding of the tensions within public health so that we can offer clear-headed recommendations for policy, regulation, and future research.
