tripping intensely without knowing you've been given acid (or even what acid is) could be a terrifying experience and deeply traumatic

I vaguely remember the MKUltra ones had bonkers high doses for long periods of time (like, a month). These guys, idk. It would be pretty distressing if you didn't know you were getting dosed but you still had to show up for your drill sergeant to yell at you to do push ups or something
