Caught DD (17) vaping last night vaping. She says she's been doing it for a while is going to keep on vaping no matter what. I want to put a stop to it and stop her vaping. DH thinks there is nothing we can do stop her and she'll just keep vaping no matter what we say or do. Caught her vaping when I walked into her room last night, she knew I was coming in as she had asked me to bring a bottle of water up for her when I come up. DD described it as "just a vape" but I'm not happy about how laid back she is about this. What would you do? Would you just let her vape or would you try to stop her vaping? How do I stop her vaping?
