To me, vaping appears to be a significantly less harmful to the body than smoking: vaping is just inhaling steam infused with nicotine where as in smoking the fumes of combustion are being inhaled. I also think with vaping there also no risk of passive smoking. I am in amazement of WHO and other health bodies dragging their feet in declaring vaping almost harmless compared to smoking.

I’ve used the odd vape here and there to stop smoking and I 100% agree with you that it’s safer than cigarettes but it’s way to early to say that it’s wholly “safe”. The problem is that if you declare it safe then everyone and their dog will start vaping, (which then amplifies any outlier problems as there are more data sources. Aka teens). The unfortunate thing is we likely won’t see any declarations one way or another for a few years now. The only way to see the true costs associated with vaping is to let time take its course. 15 years from now we will have a better idea of what daily vaping does to the human body and how safe it really is.

I'm not aware of any common vape that uses pure water as the carrier fluid. They typically use glycerol or propylene glycol, so it's not just "steam".
