A new review by researchers at the University of New South Wales has raised fresh concerns about the safety of vaping, linking e-cigarettes to early signs associated with lung and oral cancer. The study analysed evidence from 2017 to 2025, highlighting DNA damage and inflammation as key warning indicators. While definitive long-term data remains limited, some cases of cancer in exclusive vapers have been reported. Animal studies also showed higher tumour risks. The World Health Organization warns that rising global use—especially among teenagers—could fuel a new wave of nicotine addiction, urging caution and stricter regulation.
