Ask HN: Any long term vapers here? Need advice

There is so much information and mis information about vaping that I just wanted to know from the source I trust about the harmful effects of it.

So far all I got is it's supposed to be 95% less harmful than smoking but what does that really mean? Is it safe or bad in general?

So wonderful if there are any long term vapers here and what are your experiences wrt to your health.
