I don't recall that young of kids, but I do recall a thread on the same situation, but it was high school kids. High school girl gave her boyfriend her inhaler, or vice-versa. Same thing; expelled, arrested while preventing a serious health crisis.
That particular case was at Caney Creek High School in Texas. Boyfriend loaning the inhaler was suspended, never went back to school - in fact was homeschooled after that. Boyfriend and girlfriend were on identical prescriptions of albuterol.

Article mentions the case as well as other zero tolerance/zero intelligence idiocies.
I got the ages wrong, the girl who loaned the inhaler was 12.
If I was one of the parents in these cases, I'd be going ballistic. This teaches kids that anyone on the goobermint payroll is a (censored) idiot. A clusterbleep.
