A new study has identified a protein that nicotine-free vape fluid increases in the lung, causing damage including oxidative stress, inflammation and breakdown of the blood vessels.

The research, published in the journal Microvascular Research demonstrates a range of damaging pathways when an in vitro model of the human lung was exposed to a common brand of nicotine-free e-cigarette.

E-cigarettes have become increasingly popular in recent years and are often seen as harmless alternatives to cigarette smoking. It is estimated that there are almost five million ‘vapers’ in the UK, compared to around 700,000 in 2012.

I've been to shops that'll keep keep nicotine concentrate around mix into the liquid if you want. They can also mix the 0mg variant in to reduce nicotine concentration. It's possible something like that happened.

Hell I make my own juice, and I make 4mg, I know how solutions work, but if I were doing a scientific study I'd try to study with something you're likely to find in the real world, and more than one type of juice. And more than one flavor, for all we know this is caused by something in Flavor Art's watermelon flavor that could have been in all three watermelon juices, I'm still questioning their methodology.
