Unrelated to the hysteria but there was a long term study recently published. I didn’t read the whole study, only the article and abstract/conclusion that are linked in the article.
Quote:
They found that the vapour could trigger the death of healthy airway epithelial cells - even in products without nicotine.
They also showed, for the first time, that extracts of the vapour interfered with the immune system by altering the functioning of macrophages, the cells that lock away dead and dying cells in our bodies.
The researchers say the findings, published in journal Respirology, show e-cigarettes should not be considered harmless.

The only conclusion was that the vapour isn’t harmless, it doesn’t appear to comment on how damaging it can be or how much damage smoking cigarettes can do to the same cells. Might be minimal harm. Curious to see if we get any more actual studies. Much like marijuana it may be difficult to obtain proper grants and funding due to the demonization of the product.
