Koalas in Australia eat eucalyptus leaves. A chemical in the leaves produces a mild euphoria and the Aboriginals have used it in various way for thousands of years.
Koalas eat only eucalyptus and due to the chemicals in the leaves, remain in a constant, mild euphoria. Doesn't this guy look high to you?
And while I'm on it, another interesting thing about eucalyptus leaves is the high oil content. This oil is very flammable. Wild fires in eucalyptus forests can be quite intense. I always wondered--and have never had answered--what happens to koalas in these fires? They're doped up and can't exactly run away very fast, plus they're full of oil from the leaves they eat. They're like little oil lamps. I'd expect to see small explosions all along the treetops from the exploding, oil-filled koalas.
