As an example:
In my home town of Los Alamos New Mexico in the mid 80’s it for some reason became a thing for a few weeks for my fellow middle schoolers to crush sweet tart candies and snort them. Why? I have no fricking clue, and am proud to admit that I never tried it. I suppose it may have been to shock the norms into thinking you were doing cocaine, or to look Gangsta in a town that was blindingly white with no real access to hard drugs, or just being so bored that even a shock of pain might seem fun. But it got bad enough that the nurse had to make specific announcements that this was not a good idea, would not get you high and could possibly mess up your sinuses.
Please someone tell me that my school wasn’t the only one where doing something weird or idiotic suddenly became fashionable?
Bonus points for those who are brave enough to admit that they themselves engaged in said activity.
ETA: For those parents/teachers out there, weird fads at your kid’s/student’s school are also welcome.
