Granted it’s been a bit since I’ve been in highschool but mine didn’t remotely have that level of security. We had a rent-a-cop show up maybe twice a week who did breathalyzer tests as people came into the school. There were two entrances though so people just went to whichever one they weren’t at. They also tried having a drug dog come in every so often but we revolted and all the students started putting open bags of poppy seeds and dog treats in our lockers so that didn’t last long lol
