“Human cells were submerged in nicotine and in off-the-shelf bought carcinogenic nitrosamines,” Professor Hajek said in a statement to the Science Media Centre. "It is not surprising of course that this damaged the cells, but this has no relationship to any effects of e-cigarettes on people who use them."

“In the other part of this study, animals were exposed to what for them are extremely large doses of nicotine and this also generated some damage, but this too has unclear relevance for effects of vaping."

Nevertheless, while the findings don’t necessarily say anything we don’t know, it’s promising to see that the research is coming together and seeming to suggest that vaping is not without health risks. So far, however, it appears to be notably less damaging than cigarettes. A comprehensive report from the US, published last week, also found that vaping was notably less harmful than cigarettes and maintained there's "substantial evidence" it could be a useful tool to quit smoking.

Dr Ed Stephens, from the University of St Andrews in Scotland, summarized the results by noting that this new research is "consistent with the widely-held view that vaping is not without risk of cancer and other diseases, but that risk is usually considerably lower than smoking."
