Australian researchers have issued one of the strongest warnings yet about vaping, saying a major review of evidence suggests e-cigarettes are likely to cause lung and oral cancer. The review found signs of DNA damage, inflammation and other pre-cancerous changes, and researchers urged regulators not to wait decades for perfect certainty before acting.\n\nWhile they stopped short of saying vaping is as harmful as smoking, the authors said it is not safe and should especially be kept away from children and non-smokers. Experts stressed that vaping may not be a harmless alternative, and called for tighter limits on access while the long-term risks continue to emerge\u00b7
