How to get overdoses from pills instead of highly controllable doses from vape pens.

At least in the United States, most schools are not a place of privacy as the schools have a certain right to authority over their pupils. Consider Tinker v. Des Moines and what it meant for freedom of speech in schools. That case won students the right to freedom of expression. It's important, but in certain cases it becomes limited by Morse v. Frederick, a case that ultimately meant that such expression must not disrupt the learning environment. All of this is to say that students have certain freedoms until expressing those freedoms is disruptive to the learning experience, and I don't think there's any solid argument that would not consider vaping disruptive to the learning environment. Considering this as an invasion of privacy is a moot point when you consider that students don't really have the same rights as adults, especially in public school situations.

(In response to the OOP, not the OP here)

Fuck off snitch mind your own goddamn business!

The funny thing is: This is very likely just a VOC detector with a fancy API. I can't imagine that they spent too much on actual hardware development, especially as they are afaik not a real hardware company.

So it will be triggered by VOC.

You know what else does cause a lot of VOC to be distributed in a environment?

Yeah. Taking a proper shit.

This has very likely never been tested on an actual toilet.
