Yep, it's not just us humans who seem to have a tendency to get high on substances. Dolphins are doing it too! 900 hours of video footage which was recorded for a documentary, using hidden cameras concealed inside turtles, fish and squid, shows how dolphins have figured out how to get high by chewing on puffer fish. They chew on the puffer fish until it releases the exact right amount of a nerve toxin to get them high without running the risk of death. Amazingly, the dolphins then pass the puffer fish around to each other, just as humans do with marijuana joints, and then they hang around at the surface of the water in a trance-like state as though they are obsessed with their own reflections!
