No problem with the principle of the place she went to. Kids who have gone off the rails (and it sounds like this was about more than her wanting to be a hairstylist) can respond really well to those kinds of things and I personally think they can be character building and beneficial.
Having her kidnapped however? What in jesus fuck is that about? And DRUGGING her? I have no words. Surely it's illegal to drug your child? And to send them off with strangers when they're drugged too 
I'm glad it worked out but can you imagine how that could have backfired? Talk about risking your child never trusting you again.
The guardian are specialists at finding awful parents. Does anyone remember that tattoo mother?
