Frogs are pretty cool. Especially the exotically colored ones and the poisonous ones. What is the frog that people can get high from licking?
There are several toads whose venom contains tryptamines such as bufotenin, maybe DMT, 5-meo-DMT, 4-aco-DMT I'm not sure.
I have smoked DMT, it brings on an intense but short psychedelic experience.
In Australia we have Cane Toads, which were introduced in the 1950's I think. They were brought here to eat cane beetles, which damage the sugar cane crops.
The cane toads thrived in our conditions, with no apparent predators. They reached plague proportions, and are slowly but surely spreading from the cane fields of Queensland, west through the pristine national parks of the Northern Territory, and south into New South Wales.
Cane toads have poison glands above their ears, there is probably some kind of milking technique so as not to be squirted in the face.
