I find it interesting that this substance is psychoactive in so many animals, from hornets to frogs to humans. Are there any other examples of something like this?
You find it interesting? Interesting enough to justify mentally torturing animals?

This is cruelty disguised as science.

> ... after administration of 15 micrograms of LSD per kilogram of body weight.

That's a huge amount. 15ug/kg would equate to 1200 ug for a 80kg human, which is a lot.

That goat was tripping balls, no wonder it was painting the infinity symbol (8) with its movement patterns :).

Also, the 7000 pound elephant who died, was injected with 297mg of LSD, which would amount to 297,000ug/3175,15kg = 93.5ug / kg, which is insane.

Did those "scientists" even know what they were testing ?

But anyway, interesting results. I'm curious if they tried dosing an animal and a human at the same time to see how human-animal interaction and communication is affected.

They thought they did. Check out the original paper. They found that many animals needed higher (relative) dosages to get affected, administered up to 1mg/kg to macaques (no death), and found that 6.5mg/kg was necessary to kill a cat.

Interesting read: It's quite surprising that they didn't start with a lower dose for Tusko the elephant.

:)

Now you know why it's illegal.
