**“The comparison between mice breathing vapour and mice breathing air is not statistically significant. There is no sample size justification and no power calculation. There is no message to the public here – I suspect these results are just noise.” (Britton) | |||
**“The study has unclear relevance for human vapers. Rodents were exposed to what are for them huge concentrations of chemicals that bear no resemblance to human exposure from vaping. Several animals in fact died during these exposures. The authors assigned the effects they observed to a carcinogen NNK – but NNK has been measured before in human vapers, and it is known that exposure from vaping is either negligible or none.” (Hajek) | |||
