expert reaction to qualitative risk assessment on the carcinogenicity of e-cigarettes
A recent qualitative risk assessment examining the carcinogenic potential of e-cigarettes has sparked strong reactions among public health experts and researchers. While the study suggests possible links between vaping and cancer-related mechanisms, several scientists have criticised its methodology and interpretation of evidence. Experts highlight that the review does not directly compare vaping with smoking, which they argue is essential for understanding relative risk. They also point out that detecting trace levels of potentially harmful substances does not necessarily translate into meaningful health risk, particularly without considering dosage and real-world exposure. Concerns have been raised about selective use of evidence and the absence of clear criteria for assessing causality, leading some to question the reliability of the conclusions. At the same time, researchers emphasise that while vaping is not risk-free, current evidence indicates significantly lower exposure to carcinogens compared to smoking. The debate reflects broader tensions in interpreting emerging evidence and communicating risk, particularly in areas where long-term epidemiological data are still limited.
