I'm glad to see this. Vaping is one of the great technological triumphs of the last few years: a way to eradicate most of the dangers of smoking without losing the pleasure of it. We should celebrate it. But instead nearly everything I read about it is critical. 
Is it completely safe? No. Is it much, much safer than smoking? Yes it is. And yet there is more critical coverage of it than cigarettes. That is insane and it will lead to more deaths.
For those who want more info on the health difference between vaping and cigarettes, this Public Health England video is very good indeed
