Passive (And Active) Vaping Causes No Harm Say Two More Studies

Last week we wrote about a very positive study on passive vaping which showed using an e-cigarette had no effect on the blood of users and non-users .

Now an All Voices articles discusses two more studies which show there is no reason for concern about passive vaping – or direct use of e-cigarettes!


An All Voices article (link since removed) announced that the ClearStream study has found noting in the vapour of e-cigarettes that could cause harm to non-users or users.

The final study stated that: “…the quality and quantity of chemicals released to the environment are by far less harmful for the human health compared to regular tobacco cigarettes.”

German Study

Meanwhile a German study also set out to investigate the vapour released by e-cigarettes.

When measuring vapour on exhaled breath they found:

  • 5 of the compounds measured were non-toxic
  • 4 other chemicals measured were within the safety exposure range with a margin of 90%

A detailed analysis of the study can be found on the All Voices article. 

Watch Out for the Spin

Despite the positive results, expect spin from people whose interests are threatened by e-cigarettes.

As before, this will probably take the form of highlighting chemicals found without pointing they are within safety limits.
