I know exactly what my children do.
Yes, my teenage daughter vapes, I gave her the mod and
tanks she uses. They do not leave the house. She had started smoking and this was the way to stop that. I also refill her bottles and check her
tanks every few days (randomly) to ensure nothing else is being put into the tanks.
My almost teen twins do not vape, don't have time for that type of stuff and are totally disinterested. I give them 2 years...
Thing is, I remember being 14 to 16 yo. I started smoking at 14 and didn't stop until 37 years later.
They are going to try! Take the mystery out of it as soon as possible, take away the restrictions (at least at home) on what they can and can not do and the danger aspect disappears.
I also know that most of my side of the family has smoked for generations. Nicotine does help a lot of folks in it's own way. I want to at least let my children be safer.
