How did people go to school high?

I used to pick up some people for school years ago and every single time they would smoke a bunch of weed before we got there. I tried it a couple times outside of school and I always had the thought of, how could you possibly enjoy being like this in school where there’s a threat everywhere. I’m now a regular user and even though I’m used to it now, I still can’t even go into a store without having a mild internal panic attack. (Currently stoned btw✌️❤️)
