Are phone bans REALLY what we need to be focusing on right now?
I’m in Atlanta so maybe my area is just cooked, but even in middle school everybody either vaped, had tried it, smoked weed, or knew hella people who did. By high school it’s actually insane. I’d genuinely say like 30-40% of my school does some type of drug, vape, weed, alcohol, whatever.
And yea I get the phone ban. Kids are addicted to their phones and it probably does help in class. But banning them from even being in the school while drug use is this normal feels crazy to me.
Teachers will catch your phone out for 3 seconds and send you to the office, meanwhile the bathroom smells like Snoop Dogg’s living room and everybody just keeps moving 😭
I’m not saying ignore phones, I just feel like schools are putting WAY more effort into fighting phones than stopping kids from getting addicted to actual drugs.
