Apparently it's possible to get high from cane toads

[Antarctic Termite]

Boiled into a broth or licked, you can expect mild hallucinations for an hour or so in addition to severe poisoning and a decent chance of death.

I thought that was just the elation from exterminating them?

[ReonenMiruel]

This is one of the reasons why you kill them and not lick them.

And if you boil one and watch it with your friends, you can discuss whether or not it realized it was dying when you are high.
