Vaping likely to cause lung and oral cancer, Australian researchers find in new review of evidence

Australian researchers at UNSW Sydney conducted a comprehensive review of evidence from animal studies, human case reports, and laboratory research published between 2017 and 2025, concluding that vaping is likely to cause lung and oral cancer. The analysis examined cellular and tissue damage in the mouth and lungs caused by e-cigarette inhalation, representing one of the most detailed assessments of vaping's cancer risks to date. The researchers urged regulators to take action now rather than wait decades for conclusive risk levels to emerge. The findings add significant weight to growing concerns about vaping's long-term health effects, particularly as e-cigarette use has expanded globally among both adults and young people. The review underscores mounting pressure on policymakers to strengthen regulations around vaping products.
