This document discusses e-cigarettes and their potential role in tobacco control. It notes that e-cigarettes have changed the landscape of tobacco control and could be an important tool for harm reduction. While more research is still needed, the current evidence suggests that the benefits of e-cigarettes for helping smokers quit may outweigh the potential harms, especially when compared to the proven harms of smoking tobacco. The document advocates for a public health approach that engages with e-cigarettes as a harm reduction strategy but continues monitoring the evidence for any risks.
