I'm guessing the OP's daughter is probably a teen. When I was a teen, my mom never kept any medication locked away from me, it was all kept in our easily accessible medicine cabinets. She trusted me though, and I was responsible, she knew I wouldn't touch it, especially if it wasn't mine or something I didn't use. Maybe the OP thought the same thing, she trusted her daughter not to touch the sleeping meds, much less drug her with them. That trust would definitely be gone now though.

I was also never assumed to be a danger to my parents. I had free access to any medication in the house at the age where I was old enough to have a phone because I could be trusted not to drug other family members when they upset me.

As someone that is a teachers assistant while in school to be a teacher, I've seen this happen to teachers too over phones being turned off, turned in for being used in class, or required to put the phones in a box during class. It's actually terrifying.

Why is everyone who replied with military school being down voted? I didn't go to a military school and I wish I did, they teach discipline and respect for others especially authority figures. Which by the sound of it, OP's daughter needs it. That and a psychiatrist/counselor, girl is crazy.

It's because the military isn't really known for psychogical care, which she clearly needs more than being screamed at for years. Respect for authority is important, but someone like this needs actual medical help which military school wouldn't really help with. This is the type of thing that serial killers start out with, hurting people they "love".

Not all authority deserves respect though. And I feel like they teach fear more than respect. "Respect" me or be punished. That is not a way to teach someone.
