I am sure you know that vaping has been around for 20 years, this year. If not, you know now. So all this „we don’t know enough yet“ is getting a bit boring.Funnily you don’t apply this anthology to other things in you profession like drugs, vaccines, operation methods, etc. if there is any chance that it could save a life you will use them.That vaping is safer than smoking is an undisputed fact and it could save smokers lives.But as an obstetrician it is clearly not your field of expertise.
