Regulation of social media probably polls pretty well, I think polls have even found that most high schoolers want to reduce or end their usage of it
Makes no difference -- it's completely unenforced by the teachers. They're practically physically adults, teachers don't want to risk the confrontation, etc. And the kids suffer for it.
And my youngest uses no social media but their mind is still eaten by constant phone usage.
More than social media, the problem is the device. The form factor.
The "smartphone" is a malevolent technology.
Neither give a shit about their phone and we have to force them to take it if they are going out so we can call them if we need them.
