Efficacy of e-cigarettes as aids to cessation of combustible tobacco smoking: updated evidence review

Abstract

This systematic review and meta-analysis aims to summarise the current published peer-reviewed randomised control trial (RCT) evidence on the efficacy of e-cigarettes – nicotine and non-nicotine – for the sustained cessation of combustible tobacco cigarette smoking and for the cessation of ongoing exposure to nicotine. The review also considers the evidence in the light of potential competing interests.
