I wondered the same thing. I was a 17-year-old college freshman when my upset roommate asked me to get her a glass of water. I had no idea she was going to swallow a handful of pills. I called the cops, she got her stomach pumped and all was well.
But there was no care or counseling for her or me. She got kicked out of school, and I got to talk to adults who told me they couldn't get involved. I had enough sense to seek out psych services, where a single session cost my weekly food budget. I would question the value of any statistics gathered during that period of time (1968).
