And toad tripping dogs are just the beginning. 

Everywhere scientists have looked, they have found animals who love to party

 Bees stoned on orchid nectar, 

goats gobbling magic mushrooms, 

birds chomping marijuana seeds,

 rats on opium,

 also mice, lizards, flies, spiders and cockroaches 

on opium, 

elephants drunk on anything they can find, 

usually fermented fruit in a bog hole, 

but they're known to raid breweries in India as well

felines crazy for cat-nip, 

cows loco for loco grass,

 moths preferring the incredibly hallucinogenic datura flower,

 mandrills taking the even stronger iboga root.
