When I went to CEDU, some of the kids may have experimented prior to attending, but few -- a handful-- were addicts. In fact, you had to detox before you went to CEDU. Of course, that didn't stop staff from labeling you an addict if you ever tried pot. This was their leverage against you.
As far as promiscuous? Normal, flirtatious teen behavior was deemed promiscuous. We ended up getting a more fucked up view of sexuality at that "school" than we had in the real world.
And funny how they loved to label the girls whores but had nary a thing to say about the boys' past sex lives. Unless it involved animals or homosexuals. Fuck feminism and any other ideology. It's just plain old run of the mill hypocrisy.
