I don't know if that's a private school or not, but that stuff happens at public schools too. My (public) high school is starting a program this fall where parents can sign up their kids to get pulled out of class and given a UA. Then the results of the UA are given to the parents (but not the police or school). I think its complete bullshit. I'll turn 18 a couple weeks after school starts so maybe I'd be able to get out of taking one if I'm an adult. I wouldn't be surprised if my parents signed me up for it since they found a bag in my room a couple weeks ago.
