My brother lives in Albuquerque, town of his birth, where the air is too dry to cause any asthma flare-ups, and where he can say "I ate at that diner!" for every diner in Breaking Bad and Better Call Saul.
He knows many meth addicts, because yes, they do have a lot of meth there in New Mexico, and he's always giving me little peeks into the world of addiction. Most recently, he told me about "Treeple."
Per Dave, and that link to Urban Dictionary, Treeple are the shadowy people who live in the trees and follow paranoid meth addicts.
It's odd to think that a drug causes reliable, specific hallucinations. I know I've read that people who take ketamine share a hallucination in which they see tiles and then fall down a hole and meet God. Like, "Have some K, say hi to God for me."
I have questions. If you take Ketamine and Meth at the same time, which hallucination do you have? Or do you have both? Do the tree people follow you down the hole where you all have lunch with God, until they start whispering to God and He turns on you? Does the ketamine trigger the hippocampus, hence religion, hence God, and if so where is the part of the brain in charge of tiles? And where is the paranoid lobe, or the tree neurons?
All of this sounds a little like the urban legends about people on LSD trying to fly. I don't know how much to believe. Let me know if you've seen God or Treeple, or if you have a friend who has.
