capuchin monkeys like to eat millipedes which venom has cyanide. copied Of course the risk of agonizing death has never stopped anyone from getting high, so the capuchins (one of mankind's closest relatives) gather in huge groups and swap hits of 'pede. It's like a frat party, but with slightly more flinging of feces.
Reindeer love to eat shrooms and apparently alaskan people drink the reindeer's pee in order to get the effects as well, since it doesn't metabolize in the body and get excreted through the urine. Oh, and big horn sheep suck on rocks for a special type of lichen that gives a narcotic effect.
My obvious answer is cats AND CATNIP. They go out of their minds over it, and there appears to be some evidence that they get some sort of "high."
How much would it take to get a whale stoned? And what kind of ballads would they write in their heads under the influence? https://www.youtube.com/watch?v=elw-459P8kE
How in hell do Alaskans collect caribou urine? They herd reindeer in Alaska? I'm a doubter on this one.
