I did something like this once…except I laced a joint with datura which is a drug that makes you see spiders and people and shit, gave it to a friend but he had about 10 or so kids pass it around in the bathrooms…I swear to god within 10 mins everyone was talking straight gibberish and screaming, vomiting, it was an absolute catastrophe. A teacher had to call the ambulance and round up all the kids who were tripping and get them sent to the hospital, fights broke out and stuff, and we all had to go home early. Also one of them literally became a paranoid schizophrenic after this and it was all my fault :/
