Humans aren’t the only creatures that suffer from substance abuse problems. Horses eat hallucinogenic weeds, elephants get drunk on overripe fruit and big horn sheep love narcotic lichen. Monkeys’ attraction to sugar-rich and ethanol-containing fruit, in fact, may explain our own attraction to alcohol, some researchers think.
Footage from a new BBC documentary series, “Spy in the Pod,” reveals what appears to be dolphins getting high off of pufferfish. Pufferfish produce a potent defensive chemical, which they eject when threatened. In small enough doses, however, the toxin seems to induce “a trance-like state” in dolphins that come into contact with it.
