There's a scene in the Mayans MC television show where there's a secret detox facility run by a veterinarian out of the back of an animal shelter. The doc says, "welcome to wonderland." All of the addicts were locked in animal cages. It was pretty weird and doesn't make much sense unless we're talking about the bite that has no cure. Then it makes sense.
