I also grew up in the days before “ADHD” was even a diagnosis for lack of attention in school - let alone the outpouring of Ritalin prescriptions to follow.
I graduated high school in the mid-90s - this was known as being “bored as shit” sitting in class... of course I had a deficit in my attention...
Not necessarily, Morris County seems to hang on to them for a long time. I've seen where they had them for 12 years after a case was closed. Passaic County on the other hand, will tell you that you have 60 days from the disposition of your case to get them back/sell them or they go to captain crunch.
