Featured there is Amanita Muscaria, which isn't really that poisonous. White Amanitas are lethal, never touch those, but with Muscaria you could have some fun.

Some even theorise that the reason Santa is red and white comes from Amanitas, basically a siberian shaman got fucked up on shrooms and climbed down the middle pole of the tent to give everyone else shrooms as well. Which is why Santa comes from the chimney and gives colorful presents. :) (Or so some people have theorised, I'm not asserting it as fact lol.)

edit and also reindeer love chomping on amanitas, and amanitas are associated with feelings of "flying". and the way these people would get high is that the shaman would eat a lot of shrooms, then after he got high he'd piss in a bowl and that piss would get people really high.)
