Can poison from toads harm frogs?

A guy at work told me that toads secrete a poison from their glands if they feel threatened by a predator and that he was holding one and felt the wetness of it, well that got me thinkingà. If IÆve got a bucket of frogs and toads together could the toad poison get on the frogs and hurt them?

Well yeah, I told the guy it was probably just piss cos I get pissed on all the time but he wouldnÆt believe me. Never knew it was just water though, I thought it was proper pee. Some teenage lads helped me frogging once and they were putting toads in their pockets and up their sleeves, I told them it wasnÆt wise but boys are boys and they didnÆt mind getting mucky. DonÆt think IÆm up for drinking it ever though, not even to see if it does taste like water.

Hopefully toads I catch ainÆt too stressed in the bucket though IÆd better remember that if I add in a squashed alive one ever. At the end of the night I grab the injured ones and take them down the road to the bridge to be run over properly, if I find a healthy frog or toad on the way that gets added in aswell before I release them again. Does toad poison only affect frogs? Could the poison from one toad hurt another toad or are all toads immune to toad poison?
