More than 2000 unknown substances have been found in vaping mixtures
Experts from Johns Hopkins University (USA) conducted the first large-scale comprehensive study of vaping mixtures and compositions for electronic cigarettes. They were not looking for something specific and did not set out to prove anything, it was a typical search for all the chemicals present in the samples. To simplify the task, we took only products with imitation of the taste and smell of tobacco, without other flavors, and the study itself was carried out using high-resolution mass spectrometry and liquid chromatography.
As a result, scientists counted more than 2,000 different chemical compounds, most of which could not be identified. In particular, six dangerous substances were found: three industrial chemicals, a pair of flavors with proven harm to the human body and one pesticide. But most of all, scientists were surprised by the presence of caffeine – nowhere in the description of vapes does it indicate that this potent psychostimulant is used there.
Another mystery was the traces of hydrocarbon-like compounds in vape aerosols, already in the form of condensate. Usually such substances are formed during gorenje, but it cannot be excluded that they could have been obtained during vaporization. And this raises a new question – what is really going on inside the vape, what processes are going on in it? If we consider that earlier Australian scientists found nicotine, benzaldehyde, and even immunosuppressants in these liquids, a natural question arises – what is the true composition of this “product”?
The researchers emphasize that they do not yet have the right to call vapes and similar devices dangerous to health, there is too little information for this. But this is certainly not a “safe” alternative to classic cigarettes. Most likely, manufacturers mislead both consumers and regulatory authorities by adding unknown components to liquids at their discretion.
