Cell studies on e-cigarettes: don’t waste your time reading (at least most of) them


By Dr Farsalinos

I have repeatedly mentioned that there is no need for vapers to waste your time and brain activity reading cell studies. In the majority of cases, the protocols and experimental procedures are irrelevant to human effects. However, over the past few days I have been repeatedly contacted by vapers asking me to comment on a new study published by the American Journal of Physiology: Lung Cellular and Molecular Physiology. The study has an equally to the journal impressive title: “Endothelial disruptive pro-inflammatory effects of nicotine and e-cigarette vapor exposures”.

There is no need for in-depth analysis. I will just show you part of a figure from the paper, together with some notes I added.

Although cell studies have some value, presenting them with press statements making ridiculous claims about supposed findings and interpretations makes the whole issue look more like a joke. This is directly discrediting the value of cell research, just because e-cigarettes are a hot topic which can generate a lot of publicity. Expect to see more coming out, but please understand that I will stop commenting on such studies because the publicity accompanying them is politics and not science.
