@Youhavetobejoking My youngest, also a DD, did far worse similar to yours at that age. It was utterly beyond the pale for me, as I was the most law-abiding teenager ever known (didn't drink, didn't smoke, didn't have 'unsuitable' friends, etc, etc). My other DC were more like me, but I've been on a right old rollercoaster with the last one.
Vaping: I have learned that this is not a hill upon which one should die. They grow out of it.
Social media: I cannot begin to describe how much I loathe social media. But it is how they communicate now.
I am basically opposed to drunkenness, vaping, smoking, casual sex etc etc etc, so my gut feeling is always to clamp down in the hope that it will make them go away. But it won't. I do have some absolute 'house rules', which amount to "no drugs anywhere near my house", "smoking/vaping outside only"; "don't you dare wake me up when you come home drunk"; and "no casual sex in the house".
With a DC of that age, punishments/confiscation etc won't do the job. If it has got to this stage, what matters is that they will still tell you when things have gone wrong, and will trust you not to blow your top (even if what they are telling you is completely alien to you). You have to let go of the reins at 16+, but do whatever you can to keep the lines of communication open. It's not easy, but it's actually the only way you can help to keep them safe.
If it's any consolation, this same DD is now at university and is now not that interested in going out/drinking/vaping, because she did it all when she was 16. She said that clubbing is really boring once you don't need to use fake ID.
