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 really wish these articles would be more clear about what kind of vaping they are talking about. Vaping weed, for example, likely has a different chemical composition but might pose similar or very different risks that the article never acknowledges.

Three vapes, all watermelon flavour, were purchased from an online retailer and contained different concentrations of nicotine: 0mg, 10mg and 20mg in a 2ml solution

Where the fuck can I buy 2ml of 20mg liquid? Standard these days since the dawn of mods is 3mg or 6mg, back around 2012ish you could get 3mg, 6mg, 12mg, 18mg, or 24mg, 10 or 20mg has never been a standard. On top of that the smallest bottle I've seen sold is 5ml testers, who the fuck sells 2ml?!

Even salt nic, it's usually 25-50mg. 20mg salt nic would make sense but where the dick do I buy a 2ml bottle? That's barely a bottle at that point it's a damn vial, nobody sells that shit. Salt nic bottles are usuall all 30ml, never seen a 5ml, 60ml, or 120ml.

I'm gonna need this study to link me to the online retailer, because frankly I'm not sure I believe them.

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.
