Treatment for hydrazine poisoning involves administration of
pyridoxamine.  If one is getting enough of this B vitamin, or taking
supplements, I would expect hydrazine to be less poisonous than for
someone whose pyridoxamine status is poor.  This may explain why some
hydrazine-containing species are known to sicken some, while others
eat them with apparent impugnity.
