Heart harm claims from study of just 17 vapers challenged by experts
Claims about vaping-related cardiovascular harm have been challenged following a study involving just 17 vapers, 19 smokers and 22 non-users.
Although researchers observed differences in blood vessel function and fitness, independent experts highlighted important limitations, including the small sample size, previous smoking history and the inability to establish causation.
The criticism reinforces the need for larger, longer-term studies and careful interpretation of findings. Accurate tobacco harm reduction research must distinguish potential health risks from demonstrated harm without overlooking the broader evidence on switching away from cigarettes.
