Is it safe for my husband to vape in his office?

Husband vapes all the time. It is very frustrating and annoying. I told him no around the kids in the car around me, so he does while we are outside or while he is in his office room in the house with the door shut… Is that safe? I’m super worried about it being in the house at all.

No ma’am, vaping should not be done inside whatsoever
