Do e-cigarettes help people quit smoking? A plea to focus on the evidence

Cochrane is a global non-profit, known for producing unbiased and high-quality reviews of healthcare evidence. The Cochrane review of e-cigarettes for smoking cessation was first published in 2014 and has been updated four times since then. Every update brings more evidence showing that e-cigarettes can help people quit smoking, but disagreements persist on interpretation of this evidence base. Perceptions of uncertainty regarding the effectiveness of e-cigarettes for smoking cessation can have wide reaching consequences.
