A species of mushroom that grows in the northern hemisphere can get people high, but some other chemicals in the mushroom also make you very ill. However if a reindeer eats the mushrooms, the illness producing toxins are filtered out but the hallucinogen survives in the reindeer urine. It’s called Amanita Muscaria, aka Fly Agaric and can be seen in most Alice in Wonderland pictures. Pretty red (and sometimes yellow) mushrooms with whiteish patches on the surface.

Legend also has it that the royalty in Siberia would eat them and the peasants would fight to get the noble’s night pot because he could get high on the piss but not have any of the toxins.
