What is a good thing to do when you are high?

Depends if I'm with people or not and what time of day it is.
If I'm with people we usually just put music on and talk, or just watch some funny shit on TV. It's always fun to go exploring outside if it's nice out, too.
If I'm by myself I'll play music super loudly, play video games, make food, or maybe play an instrument.

One thing I'll REALLY recommend is to buy some LED strips and put them in your room. It's really nice to have LED's be the only thing illuminating your room in any color you want while you're playing video games or something.

For the most part I just do what I'm feeling at the time haha, there isn't really any sort of structure to what I do.
