I tried further searching for the lab results on more e liquid flavorings by this same laboratory in the UK without much success-(Matcha Gurevich e cigarette flavor testing)
EDIT- Probably because I have no idea how to correctly spell his name!
Maciej Goniewicz, PhD, PharmD
Assistant Professor of Oncology

Buffalo, NY 14263
I found his name doing a search for: toxicology research of e-liquid on human cells
His was first link (though not to the specific juice testing; I'm not sure that is published yet).
If you youtube search his name you can find a couple of older videos (2-3 years old) of him. You'll know immediately this is the same person by both voice and appearance.
Also, I would offer a quiet caution about his specific juice tests; unless you are using his exact flavor AND brand the results are not universal. If you have experience mixing your own juice you will know there is a vast selection of ingredients available to anyone making e-liquid.
Mfg "A" makes a pina colada with 7 ingredients and Mfg. "B" makes their pina colada with 13 entirely different ingredients. They will taste similar but that does not mean that the level of risk is automatically the same.
I am not saying that it is useless, just don't try to directly apply it to all flavors with the same name.
