so uhhhhh a couple minutes ago my math class had a K9 unit go through it
our entire class had to sit outside away from the class while the K9 unit went through.
1 student got pulled out and their backpack.
I'm gonna bet it is drugs as the student DOES vape.
we went back in afterwards after everything settled down.
Edit: that student also says he is high a lot, from what I recall.
