I'm from QLD where these toads are abundant.
My poor arse rat friend spueezed some 30 poison glands onto some glass to get a big ball of the yellowy sticky shit that dried brownish black.
He laced some leaf with it and gave it to my rat without telling him. my rat started having colourful hallucinations that lasted about 25 minutes.
My rat has licked a cane toad for a bet but this numbs his WHOLE mouth and throat, but no hallucinations probably not enough poison. Smoking it make my rat's lungs feel a little numb. The experience is pretty crappy, or so my rat tells me.
