Crimo was known at least locally in what’s called the lofi rap community - and there are enough pictures of him online from the last several years that anyone who cares to look can see the change in him. Not the tattoos, those are obvious, I mean the way his eyes go flat and dead and vacant.

THC in high doses is just slow-acting brain poison (not even particularly slow-acting if the doses are really high). People have known this for centuries, we just had a very sophisticated pressure campaign over the last 30 years that made us forget it.
